For the straight welded steel pipe which gradually rolls the steel strip into a loop and welds the joint into a steel pipe, it can be divided into continuous furnace welding (forged welding) steel...
304 stainless steel welded pipe welding, the first use of arc welding to live fixed to prevent deformation of welding, resulting in other positions of the size deviation, and then the welding sequence...
Thirty years of playing a finger. Whether it is the development of erw steel pipe or seamless steel pipe, we have made great achievements. We are proud of the development of the whole steel pipe...
Hot-rolled seamless steel pipes are mainly used for the most underground pipeline transportation, groundwater extraction, boiler hot water transportation, mechanical processing, bearing sleeves...
Seamless steel pipe and erw steel pipe due to the differences in the level of craftsmanship and quality control capabilities of the manufacturers, there is a slight difference in the shape and size of...
The trend of pipeline development is large diameter and high strength. As the diameter of the steel pipe increases and the steel grade used increases, the tendency of the ductile fracture to expand...
Pipes are diversifying and comprehensive with the development of society. More industries are using different pipes, which requires pipes to meet more performance needs. Single pipes are constantly...
In this case, we first take safety measures: open all the underground vent pipe and electric blower, quickly immediately ventilation, if the pipeline is the case of gasoline, then it is particularly...
SSAW steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction and so on. For liquid transport: water...
Conventional barrel-shaped (or MAN) perforators are widely used in the production of hot-rolled seamless steel tubes. However, since the double-supported conical piercing machine appeared in 1980, the...
1. Elimination of work hardening to obtain a satisfactory metallographic arrangementLight annealing furnace is mainly used for stainless steel products in the maintenance atmosphere of heat treatment...
The oil casing is a steel pipe that supports the oil and gas well walls. Each well requires several layers of casing based on different drilling depths and geology. After the casing is drilled, the...
Stainless steel pipes are mainly divided into stainless steel seamless pipes and stainless steel welded pipes. The welded joints of welded pipes are often damaged by corrosion and leakage, and most of...
According to the anatomical analysis of the carbon steel seamless pipe after rolling in the automatic tube mill, it is considered that after the perforated capillary tube is rolled by the automatic...
The geological pipe and the seamless steel pipe are long-length pipes having a hollow section and no joints at the periphery, and the specifications are expressed by the outer diameter x the wall...
