ST 52 Pipe

Products We Offer

ST 52 Pipe

A variety of metals and alloys are used in manufacturing pipes and tubes that are used in our day to day life. One such pipe is the DIN 2391 ST 52 Seamless Pipe. It is a low carbon manganese steel that has good impact resistance. They are mainly used in untreated or normalized conditions. DIN 17100 st52-3n is well known for its accurate dimensions, and high performance along with durability. These pipes and tubes are said to be a cost effective solution. ST52 Steel Tube is used in machinery, irrigation, and distribution of very high, cold, and high temperature gases.

St 52 steel pipe is said to have good weldability and great cold forming characteristics. They are demanded in construction and welded components for regular engineering. Apart from this, the DIN 2391 ST52 Welded Pipe is also used in oil and gas pipelines, conveyance of gas, air steam, and other fluids. These pipes are available in the size range of ⅛ inches to 48 inches. The length of these Carbon Steel Grade ST 52 Pipe can range up to 18 m and they can be plain, beveled, and threaded. They are mostly cold drawn and have a larger diameter.

ST 52 Pipe manufacturers in India widely recommend these pipes for bridge structure, marine structure, engineering, and the petrochemical industry. DIN 2391 ST52 ERW pipe produced by us is used in all these industries and many more. They are made using fine quality raw material and pass these pipes through various tests to ensure that St 52.3 DIN 17100 Tube produced by us has retained the highest mechanical properties. Our affordable prices and timely delivery has made us one of the well-known names among st52 pipe suppliers in Mumbai.
