Dia. 12-50mm threads rebar mechanical couplers Forging rebar coupler
The steel straight thread sleeves produced by our company have been widely used in the connection of straight thread steel bars in housing construction, bridges, railways, highways, airports, subways, hydropower and nuclear power projects, replacing welding and welding of various performance indicators. It has been unanimously praised by the users. The surface is treated with anti-embroidery, without rust, oil, cracks, black skin and other defects.
Rebar connection sleeve features
1. The use of steel connecting sleeves can greatly reduce the use
of materials, and the operation is simple and not limited by the
types of steel components.
2. The steel connecting sleeve can be prefabricated in advance,
which does not occupy the construction period and has high
processing efficiency.
3. The connection is convenient, fast and simple, no electricity is
required for construction, and it can be constructed in all
weather.
4. It can connect horizontal, vertical and oblique HRB335, HRB400,
HRB500 steel bars of the same diameter or different diameter.

| Note 1: The minimum size in the table means that the sleeve raw
material adopts the mechanical properties index of No. 45 steel in
GB/T699 (the measured yield strength and ultimate strength should
not be less than 355Mpa and 600Mpa respectively), and the sleeve
manufacturer has a good quality control level. The minimum size
that can be selected. Note 2: For the sleeve without cutting the outer surface, when the outer diameter of the sleeve is less than or equal to 50mm, the increase should not be less than 0.4mm on the basis of the minimum outer diameter listed in the table; when the outer diameter of the sleeve is greater than 50mm , should be added to the minimum outer diameter size listed in the table should not be less than 0.8mm. Note 3: The minimum size of the measured sleeve shall be measured in at least two directions, and the smallest value shall be used for judgment. | |||||||||||||||
