Metal pipes are processed by high -quality pipes. Double -sided galvanized protection is used for pipe tube connection.There is a rolled positioning groove in the middle of the pipe joint. The cone forming it can make the catheter inserted and located. The sealing is good. When the gem and even the water is not easy to enter the catheter, the depth of the groove is flat and the inner wall is flat after the catheter inserts.Smooth, not affecting the thread.
Metal tube is an important component of modern industrial equipment connection pipelines. Due to its excellent performance and relatively economical costs, it is widely used in pipeline systems such as drainage, ventilation, and heating of high -rise buildings to protect wires, cables and automatic automaticThe wire and cable protection tube of the meter signal and civil shower.
Characteristic
(1) High connector strength: According to the principle of hardening the cold steel, the intensity of the straight thread rolled rolled on the pipeline increases significantly, so that the tensile strength of the straight thread connector is higher than the tensile strength of the pipes mother material.
(2) Stable performance: The connection process is not affected by the quality of the workers, so the performance is stable.
(3) Fast connection speed: Because the prefabricated prefabrication is used, the on -site assembly connection is carried out. Therefore, the pipeline of the prefabricated silk head can be stacked in a large number of prefabricated reserves in the pipeline.When the construction period is relatively tight, you only need to add assembly workers at the construction site.
(4) Wide application scope: There are basically no restrictions in the application model, and it is more suitable for the fields that cannot be rotated by turning in pipelines such as bending pipes, fixed pipes, and pipeline cages.
(5) Convenient management: There will be no phenomenon of incompatibility with pipelines, and testing is more convenient.The operation is simple, and ordinary workers can become skilled workers after several hours of study.
(6) Significant economic benefits and social benefits: shorten the construction cycle, improve the quality of engineering, reduce energy consumption, conducive to environmental protection, reduce equipment investment, have a low additional cost, and have obvious economic and social benefits.
(7) Low labor intensity: It takes only one step to process a silk head on a dedicated wire roller.
