Greenline Pipe and Fitting is a known name in manufacturing and supplying the SS 430, 439, 441 Pipe & Tubes all over the globe. We are on the top list as we provide the pipes which are made from the best quality raw material. We always maintain a huge stock to avoid the problem of shortage.
The Austenitic Stainless Steel 430, 439, 441 pipe is made from grade 441 which is a dual stabilized ferritic which contains 18 percent of the chromium and has a very low content of carbon. This grade makes it exhibit the high-temperature strength, good corrosion resistance at every temperature and also shows good oxidation at elevated temperature. The SS 441 Tubes also show many features like excellent forming, mild stretch bending, and also many users in many drawing operations. These SS 441 tubes are used in many applications like in the making of the heat exchangers, in making the parts of the exhaust, in making the elevator panels, doors and also in making the kitchen types of equipment like sinks, shelves, and shelving surfaces, etc.
These Stainless Steel 430, 439, 441 pipe have features like oxidation resistance and corrosion resistance which makes it more superior as compared to another grade of this steel. These pipes have features which make it extensively used in the automotive exhaust applications. These SS 439 Tubes are used in the applications of the sugar industry applications, in making the parts like mufflers, pipes, catalytic converters in the automotive exhaust industry. And it is also used in the paper and pulp industry, condensers, heat exchangers, etc.
This SS 430 Pipe has excellent resistance against oxidation, shows good workability, ductility, and also shows long functional life. These SS 430 Tubes are used in the industry like the marine industry, food processing industry, oil and gas industry, petrochemical industry, etc.
All these pipes and tubes are delivered after performing several tests. This test is necessary to prove that these pipes and tubes are ready to be used in a different industry. These pipes and tubes are packed in the wooden boxes and at the time of the traveling from the ship they are wrapped under the waterproof sheets.
