Greenline Pipe and Fitting is one of the largest producers and suppliers of the SS 321, 321H Pipe and Tubing We designed the SS 321 and its all grades of pipe and tube at all dimensions of size, thickness, and shape. We provide it in both the international and national markets. SS 321 Pipe is the basic austenitic in additions with Niobium and Titanium. SS 321 Pipe has many features like excellent dimensional accuracy, weldability, machinability, and crevice corrosion resistance, stress corrosion cracking resistance, oxidation resistance, pitting resistance, rugged construction and withstanding heavy loads.
The specification of SS 321H Pipe & Tubes is ASME A312, ASME SA 358 and ASTM A358. The dimensions of it are API, ASTM, and ASME. The schedule is SCH 20, 40, 30, 60, 80, 120, 160 and 140, XXS, XS and STD. The form is rectangle, round, square, hydraulic, etc. The type of Pipes is seamless, fabricated, ERW, LSAW, and welded.
Austenitic Stainless Steel 321, 321H Pipes and Tubes have excellent features and outstanding chemical and mechanical properties. SS 321HTubes common applications are sugar and pharmaceutical, chemical, engineering, chemical process heat exchangers, petrochemicals refineries, pharmaceutical equipment, chemical equipment, pressure vessels, industrial boilers, and oil refinery equipment.
DIN 1, 4878 stainless steel 321H seamless tubes, SS 321H seamless tubing, SS UNS S32109 Seamless Tubing, AISI SS TP 321H Tubing, SS TP 321H Tubing, SS TP 321H cold drawn tubes, DIN 1,4511 SS 321 Seamless Tubing, ASTM A213 stainless steel 321 seamless tubing, SS321 cold drawn tubes, SS 321 UNS S32100 Tubes, Stainless steel 321 tubes, SS 321H seamless tubes are the types of 321/321h tubes.
For making 321/321H alloy following metals are mixed together like titanium, sulfur, silicon, phosphorus, nitrogen, nickel, magnesium, iron, chromium, and carbon. There are many benefits of SS 321H pipe and tubes like high corrosion resistance and welding properties. Also when heated within the carbide precipitation range it is immune to intergranular corrosion.
Various tests are performed like a mechanical test, chemical test, hardness test, heat resistance test, etc. The packing is done in the wooden pallets and boxes after covering with environmental polybag. Several required documents are also provided with the delivery of the product.
