metal drain pipe-short

1) High joint strength: According to the principle of cold hardening of steel, the strength of the straight thread rolled out on the pipe is greatly increased, so that the tensile strength of the straight thread joint is higher than the tensile strength of the pipe base material.
(2) Stable performance: The connection process is not affected by the quality of workers, so the performance is stable.
(3) Fast connection speed: Because of the off-site prefabrication and on-site assembly connection, the prefabricated pipe with good wire head can be stored in a large amount of prefabrication in the pipeline storage yard. When the construction period is tight, just add assembly workers at the construction site.
(4) A wide range of applications: there are basically no restrictions on the application, and it is more suitable for bending pipelines, fixed pipelines, pipeline cages and other pipelines that cannot be rotated.
(5) Easy to manage: there will be no mismatch between the sleeve and the pipe, and the inspection is more convenient. The operation is simple, ordinary workers can become skilled workers after a few hours of learning.
(6) Significant economic and social benefits: shorten the construction period, improve the quality of the project, reduce energy consumption, conducive to environmental protection, reduce equipment investment, low additional costs, with obvious economic and social benefits.
(7) Low labor intensity: processing a wire head only requires one step of the process in a special wire rolling machine can be completed. [2]
