Stainless Steel Duplex s31803 s32750 317L 347H Reducers

MTSCO stainless steel reducers are available in materials like Duplex s31803, s32750, 317L, and 347H. These high - quality reducers are designed to meet various industrial needs. The duplex materials offer excellent corrosion resistance and high strength, making them suitable for harsh environments. The 317L and 347H materials also provide good resistance to oxidation and pitting. They can effectively change the pipe diameter, ensuring smooth fluid flow in pipelines. Whether it's for chemical, oil, or other industries, our stainless steel reducers are reliable components for your piping systems.

3 quality inspection processes！

1. Secondary inspection of raw materials

Our raw materials come from large factories such as Baosteel, TSINGSHAN, Yongxin...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.

2. Traceability of the production process

Hongdi is equipped with CNC lathe, automatic laser cutting machine, 1,000tons hydraunlic press, elbow mandrel machine and other major productionequ equipment.

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.

3. 100% inspection before shipment

MTSCO has professional QC team to conduct a series of inspections and experiments on the fittings, including routine appearance, PMI, size, quantity, NDT and other inspections. At the same time, we also conducts mechanical testing, chemical composition analysis, intergranular corrosion and other laboratory tests. For welded pipe fittings we carry out 100% ultrasonic or radiographic testing of the raw material and pipe fittings.

In addition, we also accept third-party inspection, such as SGS, TUV, and BV. And the factory has obtained ISO 9001, PED, CRN, M650 and TS certificates.
