Large diameter coated steel pipe
Coated steel pipe is manufactured by coating plastic based on large-diameter spiral welded pipe and high-frequency welded pipe. The maximum pipe diameter is 1200mm. Polyvinyl chloride (PVC), polyethylene (PE), epoxy can be coated depending on different needs. Resin (EPOZY) and other plastic coati...Read more -
Advantages of casing drilling
1. Reduce the time of tripping and drilling. It is about 5-10 times faster to use a wire rope to lift and change the drill bit than a traditional drill rod; 2. Save the cost of procurement, transportation, inspection, maintenance, and replacement related to drill pipes and drill collars; 3. Becau...Read more -
Matters needing attention in use of thick-walled steel pipe
The wall thickness can be called a thick-walled steel pipe. There are some doubts about this. It depends on the ratio of the outer diameter of the steel pipe to the wall thickness of the steel pipe. For example, a steel pipe with a diameter of 50 mm, 10 mm can be regarded as a thick-walled steel ...Read more -
Production process of large-diameter straight seam steel pipe
A large-diameter longitudinally welded pipe is a general term. It is produced by a steel strip. The pipes that are welded by high-frequency welding equipment are called longitudinally welded pipes. (The name is given because the welds of the steel pipe are in a straight line). Among them, accordi...Read more -
Length dimension of galvanized seamless steel pipe
1. Indefinite length (usual length) Galvanized seamless steel pipes generally vary in length, which is called indefinite length within the scope of the standard. Indefinite length is also called normal length (through ruler). For example, the length of 159*4.5 galvanized seamless steel pipe is us...Read more -
High-frequency welding technology of submerged arc steel pipe
1. Control of the weld gap: After rolling by multiple rollers, the strip steel is sent to the welded pipe unit. The strip steel is gradually rolled up to form a round tube blank with a tooth gap. Adjust the pressing amount of the squeeze roller to control the weld gap between 1 and 3 mm and make ...Read more
