♦ ANSI Standards Stainless Steel Pipe

In the building and engineering industries, stainless steel pipe is one of the more standardised materials. The thickness of the pipe walls, the diameter of the pipe, and even chemical composition are all written down as part of the American National Standards Institute standards, which are just one of many available. A hollow steel bar is a large number of pipes used for conveying fluids such as oil, gas, water, gas, steam, heat exchanger, and mechanical machine. Furthermore, they are lighter, have a higher torsional strength, and are widely used in the manufacture of mechanical parts and engineering structures. Because it is more resistant to saltwater corrosion than type 304, it is also known as "marine grade" stainless steel. SS316 is frequently used in the construction of nuclear reprocessing plants. Steel pipes are long, hollow tubes that are used for several purposes. They are made in two ways, resulting in a welded or a seamless pipe. Stainless-steel pipe is widely available with Renaissance Metal Craft Pvt. Ltd.

Wall Thickness

The term schedule refers to the wall thickness of stainless-steel pipe as classified by the American National Standards Institute. Despite this standardisation, the wall thickness of each pipe diameter is not the same. Instead, the schedule refers to the pipe's overall strength. As a result, the wall thickness of a schedule 40S stainless pipe is around 1.73mm for a 10.3mm outer diameter pipe but climbs to 9.53mm for a 323.9mm diameter pipe of the same schedule. There are four general schedules for stainless pipe: 5S, 10S, 40S, and 80S.


ANSI-standard stainless-steel pipe diameters are available within each pipe schedule. The sizes range from 10.3mm (or.405 inches) to 323.9mm (or 12.75 inches). It should be noted that not all diameters are available in every schedule. For example, the smallest diameters are not available in schedule 5S, and many diameters are difficult to find or very expensive if they are available in some schedules.


Although ANSI standardises stainless steel pipe, there are numerous stainless-steel formulas available. ANSI 304 stainless steel and ANSI 316 stainless steel are the two primary sheets of steel used in the production of stainless steel pipe. Both sheets of steel have similar chemistry and differ only slightly in chromium content.

Stainless Steel Pipe Applications

Stainless steel pipe has a wide range of applications, the most common of which are:

  • Food preparation :
  • Textile production
  • Breweries
  • Plants for water treatment
  • Processing of oil and gas
  • Pesticides and fertilisers
  • Chemical applications
  • Construction
  • Textile Machinery

Heat treatment technology of stainless-steel pipe surface

Non-oxidation continuous heat treatment furnaces with protective gas are commonly used abroad for intermediate heat treatment and final heat treatment of finished products in the heat treatment technology of the surface of stainless steel pipes. Because a bright, oxidation-free surface can be obtained, the traditional pickling process is avoided. This heat treatment process not only improves the surface of stainless steel pipes but also eliminates the pollution caused by pickling.

Bright annealing continuous heat treatment furnaces are divided into two types, according to the manufacturer of stainless steel pipes, based on the current global development trend:

(1) Bright annealing heat treatment furnace with rollers.

With an hourly output of more than 1.0 Tons, this bright annealing furnace type is suitable for heat treatment of large-size and large-volume special-shaped stainless-steel pipes. Protective gases that can be used include high-purity hydrogen, decomposed ammonia, and others. It can be outfitted with a convection cooling system to quickly cool the specially shaped stainless-steel tube.

(2) Bright annealing heat treatment furnace with mesh belt.

This type of bright annealing furnace is appropriate for small-diameter thin-walled precision special-shaped stainless-steel pipes. The hourly output ranges between 0.3 and 1.0 Tons. The steel pipe can be up to 40m long. It is also capable of processing capillary tubes in coils. For quick cooling, a convection cooling system is installed. Various protective gases can be used when heating with gas or electricity. After this furnace-type heat treatment, the stainless-steel pipe has no scratches and a bright surface.

♦ Stainless Steel Tube

The outside diameter of stainless steel tube is commonly measured, and it may be utilised in a range of applications, including several structural applications.

A hollow steel bar is a large number of pipes used for conveying fluids such as oil, gas, water, gas, steam, and heat exchanger mechanical equipment. Furthermore, they are lighter, have a higher torsional strength, and are frequently employed in the fabrication of mechanical components and engineering structures. Also utilised in the manufacture of conventional weaponry like barrels, artillery projectiles, and so forth.

Because it is more resistant to seawater corrosion than type 304, it is often known as "marine grade" stainless steel. SS316 is often used in the construction of nuclear reprocessing reactors.

Cold-finished stainless steel tube technology

Our sophisticated procedure for creating seamless tubing starts with either an extruded hollow tube or a solid bar that has been drilled to our stringent requirements. The material is subsequently reduced in size several times using various cold working processes until it meets our customer's exact size, tolerances, and temper. The tubes are cut, cleaned, and heat treated after each cold working cycle in preparation for the next cold working process.


The size of the tube is reduced in three dimensions: outward diameter (OD), internal diameter (ID), and wall thickness. We roll a taper-matched, hardened steel mandrel around the exterior of the tube while supporting the interior diameter with a die fitted with a tapered groove.

We can accomplish a large decrease in cross-sectional area in a single cold working step while reducing material loss and, most significantly, enhancing the material's microstructure. The bulk of the volume treated by tube reduction or pilgering is made up of seamless tubes.

Cold Rolling

Tube rolling, like pilgering, employs compression to minimise the size of seamless tubes. Unlike pilgering, which uses a pair of grooved, tapered dies to move the metal over a tapered mandrel, tube rolling employs one or two sets of rollers with constant cross-section grooves around the circumference of the tube.

Cold rolling is a precise way of decreasing very thin walled and/or smaller diameter tubes that are frequently employed as the final cold working phase. At Renaissance Metal Craft Pvt. Ltd we can obtain outstanding control over dimensional tolerances and surface polish while reducing material loss and enhancing the metal's microstructure through rolling.

Tube rolling is particularly suited to treating rare metals such as titanium and zirconium alloys because it involves compression.

Our cold rolling capabilities include both traditional two-roll (single roll set) tube rollers and a sophisticated three-roll technique.

Cold Drawing

Cold drawing, which is typically employed as the initial technique of size reduction for seamless tubes, decreases the diameter by dragging the tube through a die that is smaller than the tube. To fit the tube into the die, one end is swaged or 'tagged,' decreasing the diameter of the leading end before drawing. The narrower end of the tube is then pushed through the die and secured to a drawing trolley, which pushes the tube through the die. Before cleaning, the 'tag' is chopped off the tube end after drawing. In rare circumstances, the appropriate size may not be available straight from the mill of a stainless steel pipe manufacturer. The cold operation procedure can then be employed to get the appropriate size. The tubes or pipes are covered with oxalic and soap solution during the cold drawing process stainless steel pipe manufacturer. This solution works as a lubricant, reducing friction during the cold drawing process. The tube or stainless steel pipe is dragged over the bench utilising die plugs during the cold drawing operation.

As a stainless steel pipe manufacturer, we know that different types of pipes are suitable for distinct purposes, stainless steel has established itself as a widely used material for its reliability regardless of the conditions. Stainless steel is a steel alloy comprising iron and chromium. Buyers of steel pipes must be familiar with stainless steel specifications. As a stainless steel pipe manufacturer all our stainless steel grades include at least 10% chromium. The metal's tenacity and strength. Mostly due of the chromium concentration. It also contains varying quantities of carbon, manganese, and silicon. Nickel and molybdenum are added to various grades based on projected consumption. As a stainless steel pipe manufacturer stainless steel has the following advantages.


As stainless steel pipe manufacturer we can say that though stainless steel pipes are not inexpensive, but they provide the best value for money when compared to several others. Stainless steel is a long-lasting material. It is simple to install and maintain, and because it is corrosion resistant, it is unlikely to take long to replace or repair. As a stainless steel pipe manufacturer this implies that you will save money in the long run.


As a stainless steel pipe manufacturer, we know for fact that most pipe materials suffer from staining and corrosion, as the pipe is exposed to both external and internal corrosive elements, which can cause it to wear down over time. This can progressively reduce the visibility of components in iron, steel, and even concrete pipelines. All of these factors contribute to soil degradation, including sunshine, rust, and abrasion. As a stainless steel pipe manufacturer, we can confidently tell you that stainless steel, on the other hand, is extremely tough and corrosion-resistant. As a stainless steel pipe manufacturer our stainless steel's corrosion resistance is attributed to its chromium content. Each steel has at least 10% chromium. When steel is exposed to oxygen, a process known as passivation occurs. This produces a thin water and air-resistant coating on the steel's surface, which aids in corrosion prevention for many years.


As a stainless steel pipe manufacturer, we can tell you that in nature, stainless steel is a very sturdy material as a matter of fact. Alloys with greater amounts of nickel, molybdenum, or nitrogen are stronger than others. As a stainless steel pipe manufacturer, we can guarantee that the mechanically solid inox steel can withstand severe impacts and stress levels.


As a stainless steel pipe manufacturer some of our stainless steel grades are designed to withstand high temperatures. That is important in plumbing. Pipes can be put in hot climates or in areas where temperatures frequently dip below freezing. Stainless Steels withstand both extremes.

Stainless Steel Pipes are used in Equipment like

  • Instrumentation
  • Automobiles
  • Heat Exchangers
  • Surface Condensers
  • Digesters
  • Fluid Piping
  • LP/HP Heaters
  • Evaporators

As a stainless steel pipe manufacturer stainless steels are the go to choice when minimal maintenance and corrosion resistance are required, and they are utilised in a wide range of industrial applications and equipment.

Stainless Steel Pipe and Tube Manufacturing Process

Rolling mill technology was the sole method utilised by stainless steel pipe manufacturers to create stainless tubes and pipes for industrial usage in the nineteenth century. Long processes are required for this rolling method. With the use of funnel rolls, the rolled sheet strips were shaped into a circular cross section. The forge welding procedure was then used to lap weld these rolled strips. Thankfully, with the advancement of science and technology, many procedures for making stainless tubes and pipes have emerged. Being among the advanced stainless steel pipe manufacturer our steel pipes and tubes are now made utilising a continuous tube mill and multitorch tungsten inert gas. This approach does not employ the filler metal or forge welding processes.

Tube mill Process description

Rolling and welding: To begin, the stainless steel strips are subjected to many quality tests and are cut at the edges. Stainless steel pipe manufacturers then feed them to the tubes factory. The strips are routed through the appropriate number of rollers based on their size. The strip is progressively changed into a tubular shape in the tubes-mill. The fitted welding equipment is then used to weld the strip's trim edges using the TIG welding procedure. Then the stainless steel pipe manufacturer make use of the Tibo machine which removes the debris and interior weld bead in an instant. Rolled stainless steel pipes and tubes are made in this manner.

Cleaning and heating phase: Depending on the industrial requirement, the rolled stainless steel pipes are cut to the desired lengths by the stainless steel pipe manufacturer. The stainless pipes and tubes are then cleaned to eliminate the grime. Furthermore, these rolled pipes and tubes are heat treated to eliminate tensions caused by welding and forming procedures. The constantly rolling hearth furnace is used for heat treatment by the stainless steel pipe manufacturer. Temperature recorders and controls are installed in the furnace. Following the heat treatment procedure, the SS tubes and pipes are straightened and pickled to remove surface scales by the stainless steel pipe manufacturer.

Finishing process: The drawn-out tube or ss pipe is next cleaned, heat treated, pickled, and straightened. The final pipes or tubes are marked using a computerised ink jet marking equipment by the stainless steel pipe manufacturer. Before being sent on to stainless steel pipe exporters, the pipe or tube is labelled with the grade of material, size, heat number, and the stamp of third-party inspection. The resulting stainless steel tubes or pipes will be subjected to rigorous testing and quality control by the stainless steel pipe manufacturer. This is followed by proper packing and shipping. There are several stainless steel pipe applications for which these pipes and tubes are employed. Renaissance Steel is a prominent stainless steel pipe manufacturer.
