The production technology of LSAW steel pipe determines its performance

　　Talking about LSAW steel pipe, it is mainly used in oil, gas, liquid coal on land and offshore. Of course, its original material and production process have decided its special characters. Today, our topic would be its features for its function.

　　First of all, internal stress for LSAW steel pipe would be smaller than seamless steel pipe. And it would be uniformly distributed after the full length expansion.

　　Secondly, due to the inside and outside of the welding is made after the tack welding, thus, we should know that this welding process would be stable for customers’ good transportation.

　　In addition, compared with non-longitudinal seamless steel pipe, the length of LSAW steel pipe would be shorter than the seamless one. Thus, the probability of defects occurrence is very low.

　　What’s more, the pipe can be either in very large diameter with thick wall or in very small diameter with thick wall.

The difference between high-quality seamless steel tubes and inferior seamless steel tubes

　　In daily steel procurement, the most irritating and irritating thing is the purchase of inferior seamless steel tubes, which affects product quality. How to identify inferior seamless steel pipe? Here we identify through the following methods: 　　1, poor quality seamless steel pipe surface is prone to scarring. 　　Mainly due to two reasons: 　　(1) There are many impurities in the inferior seamless steel tubes and the materials are not uniform. 　　(2) Inadequate guide equipment for poor quality pipe manufacturers is particularly prone to sticking steel. Contaminated pipes tend to produce scars when they bite into the roll. 　　2, poor quality seamless steel pipe is prone to tube folding. 　　The so-called folding is a variety of fold lines formed on the surface of the seamless steel pipe, and this defect often runs through the entire product. The reason for the folding is that the manufacturer is pursuing high efficiency in order to increase the output. In the production process, ...

GCr15 tube heat treatment process parameters

　　GCr15 Pipe is a high carbon chromium bearing steel with less alloy content, good performance and wide application. After quenching and tempering, it has high and uniform hardness, good wear resistance and high contact fatigue performance. The cold working of the steel is medium in plasticity, the cutting performance is general, the welding performance is poor, the sensitivity to white spots is large, and the temper brittleness is obtained. 　　Chemical composition / element content (%) 　　C: 0.95-1.05 Mn: 0.20-0.40 Si: 0.15-0.35 S: <=0.020 P: <=0.027 Cr: 1.30-1.65 　　The heat treatment system is: steel bar annealing, annealing or oil quenching at 830-840 °C. 　　Heat treatment process parameters: 　　1. Ordinary annealing: heating at 790-810 °C, after the furnace is cooled to 650 °C, air cooling - HB170-207 　　2. Isothermal annealing: 790-810 ° C heating, 710-720 ° C isothermal, air cooling - HB207-229 　　3. Normal fire: 900-920 ° C heating, air cooling - HB270-390 　　4. H...
