Bolt inserting type: MJH 15~600A / MJHL 25~300A
Bolt rotating type: MJHT 20~600A


The hinge at the opposite side of the lock part enables you to open the clamp and cover up the leaking part of pipes easily and quickly.
MJHT is the improved version of MJH. The process is very simple and shortens working time compared to MJH or other types. ① swiveling bolt one end of which is already inserted into bar nut, ②fitting into bar washer, and ③bolting up.

Application
- Industries:
water / oil & gas / shipbuilding / civil engineering & construction / general industry / machinery & equipment/maintenance of pipeline
- Pipe Materials: steel / stainless steel / cast iron / ductile iron / copper / concrete / Cu-Ni / aluminum / PVC / PPR / PE / GRE / GRP, etc.

Product Characteristics
* Assembly-type saves work time.
* Applicable to various pipe materials. Even connects pipe of a different material. (e.g. steel pipe + PVC pipe)
* Using a (torque) wrench to install eliminates worry about fire.
* No preprocessing is required at pipe ends.
* Rubber gasket accommodates vibration, impact, noise, angular deflection, and distance between pipe ends. This makes couplings seismic design.
* Installation is done on one side. It enables products to be stored or work to be done in a narrow area.
* Stainless steel design is much lighter than cast iron product and reduces the load on pipes.
* Grip-type couplings resist axial movement.
* Slip (flexible) type couplings allow pipe expansion and contraction.
* Repair clamps provide semi-permanent repair with speed and no downtime.
* Couplings can be assembled and disassembled several times.
