Hard Saw, Low Alloy Steel Seamless Butt-welding Pipe Fittings are the design recommendations approved by the Ministry of Chemical Industry for promulgation and implementation. The contents of this standard include: general principles, tees, joints, concentric reducers, braided pipes with different diameters, pipe widths, pipe fittings connection specifications, technical accessories
This standard is proposed by the Process Piping Design Technology Center of the Ministry of Chemical Industry, and compiled by China Global Chemical Engineering Corporation. The compilers are Zuo Chouhua, Yang Zichan, Zheng Tiansu, etc., and the reviewers are Feng Yuan, Bian Maoji, Zhan Tuxuan, etc. 1 General
This standard is applicable to seamless butt-welding pipe fittings made of carbon steel and low alloy, including three (equal diameter and reduced diameter), 90 elbows (long radius and short radius), reducers (concentric and eccentric) and pipe caps, divided into two series of metric and imperial. According to the current domestic production and usage conditions, the true diameter range of these four pipe fittings is as follows: equal-diameter tee, reducing tee main pipe: 90* elbow: the nominal diameter of the large-end pipe cap of the concentric reducer and eccentric reducer is 50~600mm (24~24\), and the minimum nominal diameter of the branch pipe of the reducing tee is half of the nominal diameter of the large end. The nominal pressure of metric pipe fittings is divided into four grades: P25, 40, 64, and 100kgf/cm (i.e. 2.5MPa, 4.0MPa, 6.4MPa, and 10MPa). The whole is calculated based on the allowable stress of the material [o] = 1310kgf/cm, and the medium corrosion margin is calculated as 1.5mm. The British pipe fittings are divided into three types according to the pipe number (Schedule Number is abbreviated as Schxx): Sch40, Se80, and Seh160. The units used in this standard are: length is m (except where cm is specified), inch; pressure is kgf/cm2 (kgf/cm2*ao.1MPa); weight is kg.
For the thickness of the pipe joints of all pipe fittings, please refer to the pipe fitting connection regulations. If the orderer has special requirements, please make an additional request. 2.3 Returns
