In the production process of spiral steel pipe, if the production process is unreasonable and the machine parameters are not properly set, there will be deviations, especially for large-diameter spiral steel pipes, which is often referred to as the wrong side phenomenon. During the production of spiral steel pipe, the wrong side occurs from time to time, and there…
Read MoreBecause oil and gas pipelines are buried underground for a long time, they are very prone to corrosion problems due to soil, moisture and other factors. At present, pipeline corrosion in the petrochemical industry is mainly divided into two types: 1) External corrosion, the so-called external corrosion specifically refers to the corrosion caused by the connection between the metal…
Read MoreAlloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr,…
Read MoreStraightening is an important process in the production of LSAW steel pipes. Especially for oil casing and oil and gas pipes of API standard with high quality requirements, special pipes for machinery and equipment.These kinds of steel pipes not only have strict requirements on the steel grade and weld quality, but also have high requirements on the straightness of…
Read MoreThe anti-corrosion coating of seamless steel pipe refers to the use of paint to uniformly and densely coat the surface of the rust-removed steel pipe to isolate it from various corrosive media. It is one of the most basic methods for anti-corrosion of seamless pipes. There are many kinds of anti-corrosion coatings, and their properties and uses are different….
Read MoreClassification by steel pipe material: Steel pipes can be divided into: carbon steel pipes, alloy steel pipes, stainless steel pipes, etc. Carbon pipes can be divided into ordinary carbon steel pipes and high-quality carbon structural pipes. Alloy tubes can be divided into: low alloy tubes, composite tubes, financial tubes, high-strength tubes, precision alloys (such as Kovar) tubes, and high-temperature…
Read MorePipeline transportation is a method of transporting liquid and gas materials over a long distance using pipelines as a means of transportation. special components. Sometimes a pneumatic tube can do a similar job, transporting solid tanks with compressed gas while the cargo is inside. In recent years, the pipelines used for fluid transportation are mainly seamless pipes, and gas…
Read MoreIn the hot and hot weather in summer, there is a lot of rain, and the weather is more hot and humid after the rain. In this state, the surface of galvanized products is prone to anti-alkali (commonly known as white rust) phenomenon. If the plated goods are not picked up in time, if they are not unpacked and…
