Precision light tube knowledge (What is a precision light tube)
Precision bright tube is a kind of high-precision steel tube material after finishing or cold rolling. Due to the fact that the inner and outer walls of precision bright tubes have no oxide layer, withstand high pressure, no leakage, high precision, high smoothness, no deformation due to cold bending, no flaring, no flat cracks, etc., they are mainly used for the production of pneumatic or hydraulic components such as cylinders or The cylinder can be seamless or welded. The chemical composition of the precision bright tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
The inner and outer walls of the steel pipe have high precision and high finish. After the heat treatment, the steel pipe has no oxide layer, the cleanliness of the inner wall is high, the steel pipe withstands high pressure, the cold bend does not deform, and the flaring and flattening are free of cracks. The precision steel pipe provided by Tianjin Century Zhonglian can be used for various purposes. Complex deformation and mechanical processing. Steel color: bright in white, with high metallic luster.
The main standards: GB/T3639, DIN2391-94/C, DIN2445, EN10305, DIN1630, DIN1629, ASTM A106, ASTM A179, JIS G3445
Main material: 10#, 20#, 35, 45, 40Cr, 25Mn.37Mn5, St35(E235), St37.4, St45(E255), St52(E355)
Main delivery status: NBK(+N), GBK(+A), BK(+C), BKW(+LC), BKS(+SR
Precision light tube main use:
Automobiles, machinery parts, and other machinery that have high requirements for the accuracy and finish of steel pipes. Precise steel pipe users are not only users with high requirements for precision and finish. Due to the precision of precision light pipes, the tolerances can be kept at 2--8 wire, so many machining users will save the work, material, and time losses. Seamless steel tubes or round steel are slowly turning into precision bright tubes.
