FAQ
Q: What is the difference between ASME SA312 SCH 40 Stainless Steel Pipe and SCH 10/SCH 80?
A: The main difference lies in the wall thickness. SCH 40 is the most commonly used industrial wall thickness grade, balancing strength and cost; SCH 10 has a thinner wall thickness, suitable for low-pressure applications; SCH 80 has a thicker wall thickness, suitable for high-pressure and heavy-duty applications.
Q: What is the difference between TP316 and TP316L materials?
A: TP316L has a lower carbon content, resulting in stronger resistance to intergranular corrosion after welding, making it suitable for projects with high welding requirements; TP316 has good overall mechanical properties, meeting the needs of most industrial applications.
Q: Is this product a seamless or welded pipe?
A: Both types are available. Seamless pipe is suitable for high-pressure and critical applications; welded pipe offers cost advantages and is suitable for general industrial conveying systems. Custom supply is available upon request.
Q: Which international standards does the product comply with?
A: Products are manufactured according to ASTM A312 / ASME SA312 standards. We can provide corresponding products and testing documents for EN, DIN, or other international standards upon customer request.
Q: Can you provide MTC material certification?
A: Yes. Each batch of products can be provided with an EN 10204 3.1 Material Test Certificate (MTC), chemical composition report, and mechanical property test report.
Q: Is the product suitable for seawater or highly corrosive environments?
A: Yes. TP316/316L contains molybdenum, exhibiting excellent resistance to chloride ion corrosion, and is widely used in marine engineering, seawater treatment, and the chemical industry.
Q: What surface treatments are available?
A: We offer pickling, passivation, polishing, and wire drawing surface treatments, and can also provide customized processing according to project requirements.
Q: Can you customize sizes and lengths?
A: Yes. We support customized outer diameter, wall thickness, length, cutting, chamfering, and special processing services to meet different project needs.
Q:What quality checks are performed before shipment?
A: Before products leave the factory, they undergo dimensional checks, chemical composition analysis, mechanical property testing, hydrostatic testing, and non-destructive testing to ensure compliance with relevant standards.
Q: What is the Minimum Order Quantity (MOQ)?
A: MOQ is negotiable based on specifications and order requirements. For standard sizes, we typically support wholesale purchases and project orders.
