  DIN2391   E235 ST37.5 precision steel tube   is produced by   seamless cold drawn , and bright annealed in a controlled atmosphere furnace to keep the surface quality bright and smooth, then galvanized coating the surface. E235 grade or as referred to as EN 1.0308 steel is a non-alloy carbon steel grade. Essentially, E235 is the chemical designation for the English standard. The EN 10294-1 Grade E235 is an unalloyed steel that is well suited for machining without the use of a heat treatment.  E235 ST37.5 precision steel tube is used in a variety of industries, including oil and gas, waterjet cutting, food processing, petrochemical/chemical, and many others for fluid handling.   Oil and gas:  The oil and gas industry has many uses for high pressure stainless steel tubing. In the field, high-pressure tubing is used for down-hole control systems,  hydraulic cylinder  and pneumatic piping, chemical injection modules, vacuum systems, and mu...

  DOM steel tube is a welded mechanical round steel tube with the internal weld seam removed creating a smooth internal surface. DOM steel tube has been drawn over a mandrel to produce a tube having more exact dimensional accuracy and tolerances, and a very smooth inside and outside finish. DOM Round Steel Tube is ideal for more stressful applications requiring higher quality, increased mechanical properties, uniformity, strength, and soundness.   DOM Steel tube (Drawn over Mandrel) is an electric welded tube with all weld flash removed. Tested for weld soundness, drawn over a mandrel and retested. DOM Steel Tubing has a superior finish and wall uniformity to  seamless tubing .DOM Steel Tube is a good candidate in applications that require high stress or applications that need a mechanical tube with increased mechanical properties. DOM Steel tubing is produced from 1020/1026 steel strip then formed over a mandrel welded and flash removed to produce a dimensionally so...

  ST52.4 Hydraulic Steel Tube   is used in   hydraulic cylinder   applications without further Inner Diameter processing. It is also used in applications where precision tolerances and surface finish are required. ST52.4 High pressure hydraulic tubing is used in a variety of industries, including oil and gas, waterjet cutting, food processing, petrochemical/chemical, and many others for fluid handling.   Oil and gas:  The oil and gas industry has many uses for high pressure  hydraulic steel tubing . In the field, high-pressure tubing is used for down-hole control systems, hydraulic and pneumatic piping, chemical injection modules, vacuum systems, and much more. Chemical/petrochemical:   High pressure hydraulic steel tubing in the petrochemical industry regularly carries chemicals and other hazardous fluids that could harm equipment and personnel if improperly handled. High-pressure stainless-steel coned and threaded tubing is used to make saf...
