First, the advantages of threaded joint
1, high strength of threaded joint: according to the principle of cold working hardening of steel, the strength of rolling straight thread on steel bar is greatly improved, which makes the tensile strength of straight thread joint higher than that of steel 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: Due to off-site prefabrication and on-site assembly and connection, the steel bars of prefabricated wire heads can be prefabricated in large quantities in the steel yard. When the construction period is tight, you only need to increase it at the construction site? Assembly workers can do it.
4. Wide scope of application: there is basically no restriction on the application, and it is more suitable for the fields where bending steel bars, fixed steel bars, steel cages and other steel bars cannot rotate.
5, easy to manage: there will be no mismatch between the sleeve and the steel bar, and the inspection is more convenient. The operation is simple, and ordinary workers can become skilled workers after several hours of study.
6. Significant economic and social benefits: shortening the construction period, improving the project quality, reducing energy consumption, being beneficial to environmental protection, reducing equipment investment, and having low additional cost, which has obvious economic and social benefits.
7. Low labor intensity: it only takes one step to process a thread head on a special rolling machine.
Two. Specifications and dimensions of threaded joints
Specifications and dimensions: 3/8 inch×1/2 inch–4 inch× 2 inch
Connection mode: BSP external thread ×BSP internal thread
