Double locks type clamps are composed of two separate pieces of casing and lock part at each end. They have better tightening and wider clamping range. It is eassy to install even at large diameter pipes.

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.
