 How to distinguish the positive and negative wire coupler s of straight threaded couplers, how to distinguish the positive and negative wire couplers of straight threaded couplers? There are two ways to distinguish the positive wire and the reverse wire in the conventional straight thread connection coupler , as follows. You can hold the threaded connection coupler with your right hand. If the helix angle of the thread is in the direction of the thumb, it is a positive thread; if it is the opposite, it is a reverse thread. If you hold it in your hand and rotate clockwise, it can be screwed in, and if it is rotated counterclockwise, it is a positive wire; It can also be seen with the naked eye that each coupler of the coupler has a corresponding steel stamp.

Rebar sleeve   connection is  mechanical connection, which is divided into grades I, II , III. The grade I is that the tensile strength of the joint is not less than the actual tensile strength of the connected steel bar or 1.10 times the standard value of the tensile strength of the steel bar, and has high ductility and repeated tension and compression. The grade II is that the tensile strength of the street is not less than the standard value of the tensile strength of the connected steel bar, and has high ductility and repeated tension and compression properties. The grade III is that the tensile strength of the street is not less than 1.35 times the standard value of the yield strength of the connected steel bars, and has certain ductility and repeated tension and compression properties. The primary rebar sleeve is tensile strength of the first-level sleeve reaches or exceeds 596Mpa. In another word, the primary sleeve is a steel bar connection sleeve that reaches or exceeds 1.1 t

Rebar coupler  is applied to rebar mechanical splicing in reinforced concrete structure and is designed to connect threaded rebar with diameter from 12mm-50mm. Rebar coupler is applied to reinforced concrete construction in various kinds of construction projects. It is regarded as an innovated construction material and connection, with characteristics of energy-saving, environment friendly and high efficiency. Here DLADTO will talk about some technical advantages of it then we can know why it been highly pushed by national and district construction department. Excellent anti-fatigue nature Having passed 2 million times' fatigue experiments. Wide range of application Applicable to the same or different diameter rebars'(12-50mm) connection in any directions and positions. Energy saving The rated power of the equipment is 3-4Kw only,no need to use special electric power facilities. High-speed construction The screw thread head can be made before constructing to ensure the rebars

What determine the price of   rebar coupler ? It is determined by the specification, steel market, quality and manufacturer of couplers. 1. The specifications of rebar coupler. According to the (JGT163-2013) standard, the specification of straight threaded rebar couplers are available in Φ16, Φ18, Φ20, Φ22, Φ25, Φ28, Φ32. The price of the small specification is cheap, and the price of the large specification is high. 2. The market price of steel products. The price of coupler is fluctuates up and down with the market price of steel products. 3. The quality of the steel coupler. The quality of the processing is good, and there are many inspection procedures, so the cost is high and the price is high. 4. The manufacturer. Qualified manufacturer has complete qualification , fast delivery, and good service, the price of sleeves should be higher than the unquality supplier.
