The main characteristics, mechanical properties, and main uses of precision bright tubes in Fengye Precision Bright Seamless Steel Tube is a kind of high-precision steel tube material after finishing or cold rolling. As the precision bright tube inner and outer walls without oxide layer, withstand high pressure and no leakage, high precision, high finish, cold bending deformation, flaring, flattening and no cracks, can make a variety of complex deformation and mechanical processing. Steel color: bright in white, with high metallic luster.
The chemical composition of the precision bright tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. Precision bright tube process description: high-quality carbon steel, finish rolling, non-oxidation bright heat treatment (NBK state), non-destructive testing, steel pipe wall scrubbed with special equipment and after high-pressure flushing, antirust oil on steel pipe for rust prevention, both ends cover For dust treatment.
Precision light tube main purposes: mainly used to produce pneumatic or hydraulic components of the product, such as air cylinders or cylinders, can be seamless, but also welded pipe. Automobiles, machinery parts and other machinery with high requirements for the accuracy and finish of steel pipes.
Nowadays, precision steel pipe users are not only users with high requirements for precision and finish. Because of the precision of precision bright seamless steel pipes, the tolerances can be kept at 2--8 wire, so many machining users need to save labor, material, and time. The loss, the seamless steel pipe or round steel is slowly transformed into a precision bright seamless steel pipe.

Seamless light tube to withstand the pressure calculation formula one: to know the seamless bright tube outer diameter specifications wall thickness can withstand pressure calculation method (precision bright seamless steel pipe different materials different tensile strength) pressure = (wall thickness * 2 * steel pipe material Tensile Strength)/(Outer Diameter* Coefficient) II: Known Precision Bright Seamless Steel Tube OD and Under Pressure to Calculate Wall Thickness Calculation Method: Wall Thickness=(Pressure*Outer Diameter*Factor)/(2*Steel Pipe Material Tensile Strength (Intensity) III: Pressure coefficient of precision bright seamless steel pipe. Representation method: pressure P<7Mpa coefficient S=87<steel pipe pressure P<17.5 coefficient S=6 pressure P>17.5 coefficient S=4.
