FAQ
Q: Why choose 316L seamless stainless steel tube for chemical plants?
A: 316L seamless stainless steel tube contains molybdenum and low carbon content, which provides excellent resistance to pitting corrosion, crevice corrosion and intergranular corrosion. It performs very well in harsh environments such as acid, alkali, chloride and high humidity. The seamless structure ensures higher pressure resistance, air tightness and structural stability, effectively reducing the risk of leakage and failure, making it the first choice for chemical plant pipelines.
Q: What standards does your high corrosion resistant 316L seamless tube comply with?
A: Our products are manufactured and inspected in strict accordance with international common standards, including ASTM A312, ASTM A269, ASTM A213, ASME B31.3 and other specifications. Each batch of products is provided with a complete factory test certificate (MTC) to ensure that the chemical composition, mechanical properties and dimensional accuracy meet the standard requirements.
Q: Can you provide customized size and surface treatment for chemical industry applications?
A: Yes, we support customized services. According to the actual needs of chemical projects, we can customize the outer diameter, wall thickness, length, end processing (flat end, bevel end), surface treatment (pickling passivation, bright annealing, polishing) and other parameters to fully adapt to different working conditions and installation methods.
Q: What corrosion resistance tests have been performed on the product?
A: In order to ensure the performance in chemical media, we have carried out a number of professional tests, including intergranular corrosion test, pitting corrosion test, hydrostatic pressure test, ultrasonic flaw detection, eddy current flaw detection, etc., to ensure that the product has stable and reliable corrosion resistance and safety performance.
Q: What is the applicable temperature range of 316L seamless tube in chemical plants?
A: The product has excellent high and low temperature resistance, and the applicable working temperature range is from -196°C to 650°C. It can maintain stable performance in cryogenic transportation, medium temperature reaction and high temperature transmission systems, and is suitable for most chemical process working conditions.
