DIN 2391 St52 Seamless Pipe Tube comes under the DIN 2391 specification. There are different grades and the ST52 is a stronger grade.Our company is a leading manufacturer and supplier of the carbon steel DIN 2391 St52 pipes. The pipes can range from 1/8 inches to 48 inches in outer diameters. There are different schedules of the pipes according to the wall thickness and the outer diameter. There are sch10 through XXS and 1.73mm to 59.54mm wall thicknesses.The length of the pipes ranges from single random, double random and cut to length sizes. As the leading St52 Carbon Steel Pipe Suppliers we supply the pipes in seamless and welded conditions with cold drawn and ERW techniques. There are welded and fabricated types of the St52 DIN 2391 Carbon Steel Seamless Tubes as well. Depending on the application type, there are plain ends, beveled end and threaded ends to the pipes and the lengths can vary up to 18m as well. The St52 Seamless Tube is a large diameter pipe specification. The material is made up of carbon, silicon, manganese, phosphorus and sulfur. This composition gives the material with high tolerance and strength. The DIN 2391 St52 ERW pipe has 520MPa minimum yield strength and 600MPa minimum tensile strength. The applications include oil and gas industries, power plants, heat exchangers, boilers and in general engineering services.
