SS 317 / 317L High-Pressure Pipe Fittings are one of the ranges of austenitic stainless steel alloy that is commonly designated from UNS- S31700/ S31703 pressure pipe fittings. These high-pressure pipe fittings are mainly used in piping systems to attach straight sections of pipes. This high pressure pipe retains high pressures, temperatures and high flow of solutions.

The type 317 grade these are austenitic nickel-chromium stainless steel alloy adding up with molybdenum content that offers superior phenomenal corrosion resistance and higher strength at elevated temperature. These alloys of fittings are exhibited superior resistance to oxidation in intermittent services up to 1600 degree F whereas in continuous services up to 1700 degree F. However these improved the localized and general corrosion and features superior weldability and formability. While on the other hand, the grade 317 L is similar to grade 317, therefore, this alloy of the fitting is the low carbon austenitic stainless steel alloy. The low carbon content offers superior resistance to sensitization during thermal and welding processes. This grade exhibits superior resistance to corrosion over a wide range of chemicals, especially in acidic chlorides environments.

Both the grades of pipe fittings assures outstanding resistant to general and chloride pitting corrosion. Furthermore, it offers excellent creep, tensile and stress to rupture strength at elevated temperatures as compared to other grades. The common hot working process is done at range of 2100 -2300 degree F whereas cold working is successfully performed through stamping, heading and shearing. Therefore these alloys of pipe fittings are not heat treated thus the cold working process possess superior strength and hardness.

Testing of product
To offer superior quality and zero defect product to the customers we test and check the product on various stage of production at our premises on behalf of our quality auditors. These tests are like chemical analysis, tensile strength, flaring test, macro/micro test, mechanical test, ultrasonic test, PMI test, and flattening test. Furthermore, the test is the IGC test, pitting resistance test, radiography test, and hardness test.

Packing details
To make a safe delivery of products these are packed in wooden pallets, wooden cases and in boxes.
