S32205 Capillary Tube：

S32205 capillary is a high-performance precision pipe made of duplex stainless steel. It combines the advantages of austenitic and ferritic stainless steels, with excellent corrosion resistance, resistance to chloride stress corrosion cracking, and high strength. Its PREN value can reach above 34, which is suitable for harsh environments such as seawater, high chloride ions, and acid. It is especially suitable for use as control pipelines, chemical injection pipes, and subsea equipment capillaries in the oil and gas industry. It is also widely used in chemical equipment, heat exchange systems, and precision instruments. It is suitable for fluid transmission scenarios that require corrosion resistance, high strength, and dimensional stability. Compared with traditional 316L stainless steel, S32205 provides higher mechanical properties while ensuring corrosion resistance, and is an ideal capillary material choice for demanding industrial environments.

Quality Control Method:

First, secondary inspection of raw materials. Our raw materials come from large factories such as POSCO，JISCO, ANSTEEL, ATI, NYK, Outokumpu, TSINGSHAN, Baosteel, WALSIN, ... Each batch of raw materials requires MTC and PMI. After the raw materials arrive, we conduct PMI and other inspections again to ensure that they meet the requirements. Second, traceability of the production process. The mainly production process includes welding, cold drawing, bright annealing and plastic wrapping. Each process is supervised by experienced engineers and technicians. Each link is supervised by professional qc inspectors and photographed for archiving. The entire process uses process cards to ensure accuracy and traceability. Third, 100% inspection before shipment. Siri Tubing has professional QC team to conduct a series of inspections and experiments on the tubes, including routine appearance, PMI, size, quantity, and other inspections. At the same time, we also conducts mechanical testing, hardness testing, airtightness,UT, ET, HT and other tests. All welded coiled tubing have passed 100% high-pressure testing,with a conventional testing pressure of 40MPa and a maximum of 100MPa. In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
