FAQ: Buying Guide for 304 Stainless Steel Seamless Pipes
When should I choose 304 seamless pipe over welded pipe?
You should choose seamless pipes for applications involving high pressure, critical temperatures, or highly corrosive media. Seamless pipes have a more uniform structure and are generally rated for 20% higher working pressures than welded pipes of the same material and size.
Does Huaxiao provide Sch 40 and Sch 80 304 stainless steel pipes?
Yes, we stock a wide range of schedules including Sch 10S, 40S, and 80S according to ASME B36.19. We also offer heavy-wall seamless pipes for specialized mechanical and structural engineering.
Is there a price difference between 304 and 304L seamless pipes?
The price difference is usually minimal, but 304L is often preferred for piping systems that require extensive welding to ensure the joints remain as corrosion-resistant as the base metal.
How do you ensure the quality of 304 seamless pipes?
Every pipe undergoes rigorous non-destructive testing (NDT). We provide a complete Mill Test Certificate (MTC) confirming the chemical analysis (Cr, Ni, C) and mechanical tests (Yield, Tensile, Elongation, Hardness) as per EN 10204 3.1.
Is 304 seamless pipe suitable for high pressure?
Yes. Due to its seamless structure, it provides better pressure resistance compared to welded pipes
What is the difference between ASTM A312 and A213?
A312: For general service piping
A213: For boiler / heat exchanger tubing
What is the difference between 304 and 304H?
304H contains higher carbon for high-temperature strength
What is the price of 304 seamless pipe per ton?
Pricing depends on size, thickness, order quantity, and delivery destination. Please contact us for a customized quotation.
