1. What standard does this seamless stainless steel pipe comply with?
The pipe is manufactured according to ASTM A312 and dimensional requirements of ASME B36.19M.
2. What is the OD of a 2-inch stainless steel pipe?
The standard Outside Diameter (OD) of an NPS 2 stainless steel pipe is 60.33 mm (2.375 inches).
3. What are the available wall thickness options?
Common Wall Thickness options include Schedule 10S, Schedule 40S, Schedule 80S, and heavier schedules upon request.
4. What is the difference between Schedule 10S and Schedule 40S?
Schedule 10S has a thinner wall, making it lighter and more economical for low- to medium-pressure systems. Schedule 40S has a thicker wall and is better suited for higher-pressure applications.
5. Why choose TP316L instead of TP304?
TP316L contains molybdenum, providing superior resistance to chlorides, seawater, and aggressive chemicals, making it ideal for marine and chemical processing environments.
6. Can TP316L seamless stainless steel pipe be welded?
Yes. TP316L offers excellent weldability due to its low carbon content, reducing the risk of intergranular corrosion after welding.
7. Do you provide customized sizes?
Yes. We offer customized OD, Wall Thickness, length, end preparation, and surface finishes according to customer requirements.
8. What inspection and testing are available?
We can provide PMI testing, hydrostatic testing, ultrasonic testing (UT), eddy current testing (ET), dimensional inspection, and EN 10204 3.1 material certificates.
9. Which industries commonly use ASTM A312 TP316L seamless pipe?
It is widely used in chemical processing, offshore engineering, marine equipment, food processing, desalination, pulp & paper, and power generation.
10. Are free samples available?
Yes. Sample pieces can be supplied for quality evaluation before bulk orders, subject to stock availability.
