Attention points for purchasing   rebar coupler : 1. Random sampling for testing should be conducted. 5% of each batch should be tested, and the acceptance rate should be higher than 95%. If the qualification rate is lower than 95%, a second sampling should be carried out with the same number of new samples. After two rounds of testing, if the average qualification rate is still above 95%, then the batch of sleeves is considered qualified. If it is still below 95%, each sleeve in that batch should be individually tested. 2. The manufacturer of the rebar coupler should have a certificate of conformity and material specification. 3. The couplers should be tested for their ability to be screwed in. 4. Both ends of the couplers should have plastic protective caps. 5. The plastic protective caps should be marked with the same specifications as the rebar coupler.

Workers may encounter the problem that the  rebar sleeve  cannot be screwed on the wire head during the construction. Why the threaded steel sleeve cannot be tightened? Here let's talk about the reason: 1. The threaded pitch of rebar sleeve is different from that of the wire head. The pitch of Φ16, Φ18, Φ20, Φ22 rebar sleeve is 2.5mm, and Φ25, Φ28, Φ32, Φ36 rebar sleeve is 3.0mm. The pitches of Φ40 steel sleeves are 3.0mm and 3.5mm. 2. The tooth angle of the rebar sleeve of the steel bar is different from the tooth angle of the steel wire head. There are two types of rebar sleeve with tooth angles of 75° and 60°. 3. The wire hood is too big. Due to the insufficient adjustment accuracy of the rolling mill during the threading process, there will be deviations. The wire head cover is too large, or the gear plate of the steel bar rolling machine is not compressed, and the eccentric shaft of the rolling machine has moved. Above are reasons may cause the threaded rebar sleeve fail ...
