Common problems, causes and solutions of high frequency welding
⑴ Weak welding, desoldering, cold folding; Reason: The output power and pressure are too small. Solution: 1 adjust the power; 2 adjust the extrusion force. ⑵ There are ripples on both sides of the weld; Reason: The opening angle is too large. Solution: 1 adjust the position of the guide roller; 2...Read more -
Knowledge of rolling surface processing of stainless steel pipe
Knowledge of rolling surface processing of stainless steel pipe: 1. After hot rolling, annealing, pickling, and descaling, the surface of the treated stainless steel plate is a dull surface and a bit rough; 2. It is a better process than the general surface, and it is also a dull surface. After c...Read more -
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
