Characteristics and advantages of threaded joint

1 、 high strength and good ductility, can give full play to the strength and ductility of reinforced base metal. The joint performance reaches I grade JGJ107-2003 joint standard and can be broken from base metal.

2 、 convenient connection, quick and easy operation.

3, convenient and intuitive detection.

4, steel processing straight thread can be prefabricated, sleeve can be factory production, does not account for the duration of the project, high processing efficiency.

5, construction connection without electricity, no gas, no fire operation, no oil leakage, no pollution, all-weather construction.

6, applicability, in small venues, steel reinforcement arrangement can flexibly operate.

7, can connect horizontal, vertical, oblique to the HRB335, HRB400 class with the same diameter or different diameter reinforcement.


1 、 joint strength is high: according to the principle of cold work hardening of steel, the strength of the straight thread rolled on the steel bar is greatly improved, so that the tensile strength of the straight thread joint is higher than the tensile strength of the reinforced base metal.

2, stable performance: the connection process is not affected by the quality of workers, so the performance is stable.

3, the connection speed: because of off-site prefabricated, on-site assembly connection way, so, prefabricated wire head reinforcement can be in the steel pile yard massive prefabricated storage. When the construction period is tight, only the assembly workers can be added to the construction site.

4 、 wide range of applications: there is no limit in the application of fan, more suitable for bending steel bars, fixed steel bars, steel cage and other reinforcement can not rotate the field.

5, easy to manage: will not appear sleeve and steel does not match the phenomenon, inspection is also more convenient. The operation is simple, and ordinary workers can become skilled workers after several hours of study.

6, significant social and economic benefit, shorten the construction period, improve project quality, reduce energy consumption, environmental protection, reduce equipment investment, low additional cost, has obvious economic benefits and social benefits.

7, labor intensity is low: processing a silk head only need a step, in a special rolling machine can be completed.
