Parallel Threaded Coupler

We are offering parallel threaded coupler.
the company has designed parallel threaded couplers for reinforcing bars; as they produce full strength to the joint rebar connection. Jointed reinforcing bars are cut square and enlarged using cold forging process so that their diameter can be increased and make the joint stronger. We make available parallel threaded couplers attached with reinforcing bars for efficient performance.

cutting : the end of the reinforcement bars is sawn square.cold forging : with the help of cold forging, the sawn end of the reinforcing bar is then enlarged. With this the core diameter of the bar is increased to pre determined diameter. Threading : an iso standard metric thread is then cut.

installation of nct re- bar couplers
good quality shear cut bars with sharp perpendicular cutting or saw cutting may be used. The threading is provided on bar ends with proprietary branded threading equipment and thread cutting toolsthreading of reinforcement bars must be carried out as per nct re-bar couplers by trained operator. The thread checking gauge is used for checking the threads. The threads shall be covered by thread protection plastic cap while storingthe bent bars may be threaded on threading machine provided straight length of the bent bar-end to be threaded is more than 0.5 m. If not so, the bars may be threaded in straight lengths, connected thoroughly and bar bending is carried out subsequently. The bent must be minimum 100mm apart from thread bar endthe bar is connected to coupler sleeve initially by hand tightening and then with pipe wrenchthe nct re- bar couplers full strength threaded butt joining that achieves strength with fully engaged threading of coupler and reinforcement bars. Therefore, it is essential to ensure adequate tightening of joining connection for effective load transfer

the bar or re-bar threading machine is used for cutting external thread on bars by chasing method. Hss tangential chasers are used as cutters. Bar remains stationery and die head rotates. Matric, bsp, bspt, npt, unf,unc, bsw, acme threads b.s.f etc. Threads can be cut on this machine depending upon the type of chasers. The machine mainly consists the following:
