High-frequency welded pipe
Key words:
Raw materials: coil - leveling - end cutting and welding - forming - welding - removal of internal and external weld beads - pre-correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydrostatic test - pickling - final inspection (strict quality control) - packaging - shipment. Features: Straight seam welded pipes have a simple production process, high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrower slabs can be used to produce welded pipes with larger diameters, and welded pipes with different diameters can be produced using slabs of the same width. However, compared with straight seam pipes of the same length, the weld length increases by 30~100%, and the production process is more complex.

Analysis of the Advantages and Application Scenarios of Steel Pipes
High Strength and Pressure Resistance: Steel pipes are made of high-strength steel and have a compressive strength of over 300 MPa, which is 5 to 10 times that of ordinary plastic pipes.
Key words:
Advantages lie not only in its fundamental properties such as high strength, light weight, and corrosion resistance, but also in its wide range of Applications and flexible processing capabilities.
Key words:
Steel-plastic composite pipes utilize double-layer co-extrusion technology, boasting a 60% improvement in corrosion resistance compared to traditional galvanized pipes. Demand for these pipes in municipal pipeline renovation projects has shown significant growth.
Key words:
Tianjin Lida Steel Pipe Group was established in 1993. After more than 30 years of development, it has formed a production capacity of nearly 1 million tons of high-frequency welded steel pipes and 400,000 tons of hot-dip galvanized steel pipes annually.
Key words:
Thanks to the intelligent temperature control system, the zinc layer adhesion uniformity reaches 98.5%, 2.3 percentage points higher than the industry average.
