DIN EN 1628-2 Tube manufacturer, check DIN 1628 ST37.4 Welded Steel Tubes Specification and Equivalent here
DIN 1628 Tube is made up of carbon, silicon, manganese, phosphorus and sulfur in the composition with nitrogen fixing elements such as aluminum. Multi Metals (India) is a leading manufacturer and supplier of the DIN EN 1628-2 Tube in different shapes and sizes. The material is capable of operating under high temperatures and pressures but the operating temperature is limited to 300 degrees Celsius.
The DIN ISO 1628-1 Tubing comes in different diameters ranging from 3.35mm to 152mm and the wall thicknesses range from 0.5mm to 20mm. The DIN EN ISO 1628-1 & DIN 1628 Welded Circular Tube, round tube, hollow tube and rectangular tube are some of the forms of the tubes. The material is strong and it has different standards such as St 37.4, 44.4 and 52.4.
The 37.4 grade has the lowest strength values with 235MPa minimum yield strength and up to 480MPa minimum tensile strength. The DIN 1628 ST37.4 Welded Steel Tubes can be used in petroleum, oil and gas, petrochemical, agricultural and in fertilizer industries along with heat exchangers and boiler tubes. The 52.4 grade has the highest yield strength with 355MPa and 650MPa minimum tensile strength. The DIN 1628 St44.4 Welded Steel Tubes have medium strength values. The material can be welded with most conventional methods as well. Please feel free to contact us for more information on the products and pricing.
