Generally, manufacturers have the following requirements for their quality when producing seamless pipes. 1. Ingredients. It clearly stipulates the components of hazardous chemical molecules As, Sn, Sb, Bi, Pb and vapor N, H, O, etc., in order to improve the uniformity of the components in the steel and the purity of the steel, and reduce the non-metallic material parameters…
Read MoreWhat are the factors that affect the quality of American Standard seamless tubes? 1. Temperature Temperature is the main factor affecting the quality of American Standard seamless steel tubes. First of all, the uniformity of the heating temperature of the tube blank directly affects the wall thickness uniformity and inner surface quality of the perforated capillary, which in turn…
Read MoreThere are many reasons for longitudinal cracking of seamless pipes, both material and process reasons. Taking the thick-walled seamless steel pipe as an example, if the thick-walled seamless steel pipe has poor plasticity or poor annealing, the probability of longitudinal cracking will increase, but the fundamental reason is that the residual stress of the cold-drawn thick-walled seamless steel pipe…
Read MoreWhat is carbon steel pipe? Carbon steel pipe is also called CS pipe. Carbon steel pipes are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country’s steel pipe industry. Types of carbon steel pipes: Carbon steel pipes are…
Read MoreSeamless steel pipe (SMLS) is an important type of steel. For seamless steel pipes, seamless steel pipes should also be numbered in the process of production and use. Only when the numbering is properly marked will the performance of the seamless steel pipe be better brought into play. There are also many problems to be paid attention to in…
Read More1. Pipe for pipeline. Such as seamless pipes for water, gas and steam pipelines, oil transmission pipes and pipes for oil and gas trunk lines. Faucet with pipe for agricultural irrigation and pipe for sprinkler irrigation, etc. 2. Pipes for thermal equipment. Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes, large smoke pipes,…
Read MoreThe main reasons for the lack of hardness of seamless steel pipes (smls) are the following five points: 1. The heat treatment temperature is too high This is mainly caused by the poor temperature setting of the processing technology or the error of the temperature control system. The temperature of the processing technology should be adjusted, and the temperature…
Read More1. The thickness of capillary wall shall be uniform and there shall be few internal and external surface defects; External surface polishing and internal hole defect cleaning equipment shall be equipped. 2. Compared with the ordinary cold drawn steel pipe, the cold drawn precision seamless pipe production increases the pickling and re inspection process of hot-rolled capillary, which is…
