Steel boards are widely used in the construction industry, power industry, especially shipbuilding industry. When using hot-dip galvanized steel boards for construction, the number of steel pipes used for scaffolding is appropriately reduced, which not only saves materials for the construction party, but also improves construction efficiency. Steel boards are actually new boards that adapt to the market. They…
Read More1. Spiral submerged arc welded steel pipe (SSAW) and longitudinal submerged arc welded steel pipe (LSAW) In the 1950s and 1960s, spiral steel pipes were widely used in oil and gas pipelines. In the 1970s and 1980s, they were severely challenged by longitudinal submerged arc welded steel pipes (LSAW steel pipe) and ERW steel pipes. So far, spiral steel…
Read MorePerformance comparison of carbon ERW steel pipe and spiral steel pipe: 1. Overview The welding of ERW steel pipe is the skin effect and proximity effect of high-frequency current. The process of using high-frequency current and induced high-frequency current (rising at the end of the 20th century) resistance to heat and melt the edge of the tube blank, and…
Read More3PE anticorrosive steel pipe base materials include seamless steel pipe, spiral steel pipe and straight seam steel pipe. Anti-corrosion pipelines can be divided into two categories, lined with anti-corrosion steel pipes and outer-wall anti-corrosion steel pipes. The lining anti-corrosion mainly includes cement mortar-lined anti-corrosion steel pipe, which has more applications and lower cost. The cement mortar-lined anti-corrosion steel pipe…
Read MoreElbows are used to change the direction of the pipe. The bending angles of commonly used elbows are 90 °, 45 ° and 180 °. The 180 ° elbow is also called a U-shaped elbow. There are also elbows with special angles, but the number is very few. 1. Cast iron elbow Malleable cast iron elbow is the most…
Read MoreIn our life, no matter what product is used, some precautions are needed during use. Today I will share with you the points that need to be paid attention to when using seamless steel pipes. The use area of steel pipes is relatively large, and it is indirectly destined to be rigorous in use and cannot be used at…
Read More1.Main types of anti-corrosion spiral steel pipe: Common forms of anti-corrosion spiral steel pipes are mainly 3PE anti-corrosion, epoxy resin anti-corrosion, cement mortar anti-corrosion and epoxy coal asphalt anti-corrosion. 2.Main features of anti-corrosion spiral steel pipe: 3PE anticorrosion is mainly for oil and natural gas pipelines, because oil and natural gas pipelines require high price comparison, 3PE anticorrosion can…
