SMLSCO Product Advantages
SMLSCO has a stock of 2000 tons of 304/316 series seamless pipes, including full specification 6-meter TP316L heavy wall pipes, which can be shipped within two weeks. Bulk raw material procurement reduces overall costs, PED compliance combined with complete quality inspection records enables inventory suppliers to easily achieve fast turnover and controllable risks.

Quality Control of SMLSCO 316L Seamless Pipe
Each TP316L pipe is subjected to PMI spectral analysis, 100% eddy current and ultrasonic testing. Before shipment, the size and appearance are rechecked and photographed one by one for filing; Support SGS/TUV sampling reports. The entire process data can be traced to ensure that every batch of goods received by customers has consistent quality and stable performance.

Production Process of SMLSCO Seamless Pipe

This product adopts a seven step process of perforation → multi pass cold drawing → solution annealing → acid pickling and passivation → eddy current testing → straightening → finished product inspection. Each step is precisely controlled by CNC equipment to ensure dimensional consistency, wall thickness uniformity, and inner wall cleanliness, meeting the requirements of distributors for high compliance and high turnover inventory.

Multi pass cold drawing finishing: Through continuous cold drawing and intermediate annealing, the grain size of the pipe is refined, and the strength is increased by more than 15%; The final dimensional tolerance can be controlled within   ± 0.05   mm, with an inner surface roughness of ≤ 0.8   µ m, fully ensuring the reliability of heavy wall pipes in high-pressure sealing situations and providing more competitive spot selection for inventory suppliers.

Application of Seamlss Pipe

TP316L thick walled seamless pipe has excellent resistance to chloride pitting and medium high temperature mechanical strength, and is widely used in oil and gas gathering and transportation pipelines, chemical medium transportation, seawater treatment systems, and energy equipment heat exchange lines. Its stable corrosion resistance and reliable delivery time help global industrial product distributors provide low maintenance, long-life pipeline solutions for end customers.
