ASTM A312 Stainless Steel Pipe
Stainless Steel Seamless Pipe is a broad area of piping material in different compositions, shapes and types. We are manufacturer and supplier of stainless steel pipes of all types. Darshil Trading is in the business for several years now and we also produce Stainless Steel Pipe types. There are different types and sizes available in ss pipes. The Stainless Steel ERW Pipe is electric resistance welded whereas the other types such as electric fusion welded and cold drawn pipes are also available. There are different standards such as the ASME B36.19 Stainless Steel Pipe. The B36.19 is for wrought stainless steel pipes ranging from 14 inches to 22 inches. There are other standardizations such as schedules which denote the diameter to wall thickness proportions. The Stainless Steel Schedule 40 Pipe is a medium thickness schedule.
Check Stainless Steel Seamless Pipe pressure rating and dimensions, ANSI / ASME B36.19 SS Pipes available in Round, Oval and Rectangular shape in Schedule 10/40/60 thickness
The schedules are useful in calculating the pressure containment of each pipe types. The higher the schedule, the higher the pressure containment is. The ASME SA312 Stainless Steel Pipe is used in applications where strength is the foremost concern. The Stainless Steel Schedule 10 Pipe has relatively low pressure classes. We produce different grades as well. Our ASTM A312 Stainless Steel Pipe such as A312 TP304 is applicable for high temperature services. We also produce Ansi B36.19 Stainless Steel Pipe in all grades. Although the SS Round Pipe is the most commonly used, we also manufacture SS Oval Pipe for special purposes. Our SS Rectangular Pipe could be used in structural applications as well. We supply stainless steel pipes for different industries such as domestic and low cost applications to aeronautics, chemical, marine and petrochemical industries as well.

What is stainless steel pipe allowable working pressure?
Stainless steel pipes are made up of different materials with different composition. All of the material grades have a yield and tensile strength values. The yield strength is what the material could withstand before changing shape permanently while the tensile strength is at which the pipe will rip apart when pulled from opposite directions.
Similar to the yield and tensile strength, there are working pressure and bursting pressures for pipes. The pipes have to operate under various temperatures and pressures. The maximum allowable working pressure indicates the pressure at which the pipe can operate without starting to change. The bursting pressure is at which pressure the pipe will begin to burst. There are different values of allowable working pressures for different materials, diameters, wall thicknesses and schedules. For example, the standard wrought steel pipes at schedule 40 would have 1080PSI of allowable working pressure for ¾ inches diameter.
With the increment of diameter, the allowable working pressure decreases. The 1 inch pipes have 1010PSI and the 1 ¼ inch pipes have 840PSI. The working pressure is calculated with Barlow’s formula. The yield strength of the pipe is multiplied by the design factor of the pipe to derive the allowable working pressure.

General queries of our customers about Stainless Steel Seamless Pipes
- What is the minimum diameter and maximum size in seamless pipe?
Ans:
Minimum OD: 16 inch, 406.4 mm
Maximum OD: 20 inch, 508 mm - What is the price difference between Seamless & Welded Pipe in India?
Ans: Seamless steel pipe cost is almost 40-50% higher compared to the welded pipes due to manufacturing process & raw material, click here to view the updated Stainless Steel Seamless Pipe Price List. - What is the maximum pressure of SCH40 Seamless Pipes?
Ans: Pressure rating depends upon sizes, wall thickness & temperature. For example:
1″ SCH40 WT 0.133, 100°F = 2205 PSi
10″ SCH40 WT 0.365, 100°F = 699 Psi - Why in high pressure applications SS Seamless Pipe is prefered?
Ans: Welded pipe can be cracked on high pressure while Seamless Pipes can withstand extremely high pressure without cracking. So seamless pipe can take 20% higher pressure compared to welded. - What is the weight difference between Welded and Seamless Pipe?
Ans: The welded pipe is 30% heavier compared to seamless pipe because of welding of HR coil, don’t forget to check SS Pipe Weight Chart.
SS Seamless Pipe Chemical Composition
Engineers Info
- Moly. spot test can be done to identify ss grade if it is a 304 or 316 type
- Stainless-steel pipe doesn’t look all new and also glossy straight off the welding line. In fact, it looks type of charred.
