BAIJIAN - Third party testing organization
Steel sleeve、 also known as steel joint、 is a steel sleeve used for mechanical connection of steel bars that can transmit axial tension or pressure of the steel bars. Using a connecting sleeve to connect steel bars has the advantages of high strength、 easy operation、 fast construction speed、 and being unaffected by climate compared to overlapping welding of steel bars
According to the type of mechanical connection joint for steel bars、 steel bar sleeves can be divided into straight threaded sleeves、 tapered threaded sleeves、 and extruded sleeves
Requirements for raw materials
The raw materials for threaded sleeves should be round steel with a grade of 45、 seamless steel pipes for structural purposes、 or other steels that have been proven to meet the joint performance requirements in relevant standards through joint type inspection.
; The raw materials for the extrusion sleeve should be selected based on the grade of the connected steel bars、 which are suitable for rolling processing. It is recommended to choose high-quality carbon structural steel with grades 10 and 20、 or carbon structural steel with grades Q235 and Q275
