MJS 15~600A / MJL 20~600A

MJSF, MJSFL 65~600A

Slip type couplings, without grip rings, are axially non restrained.

They allow thermal expansion and contraction of pipes.

Pipes need to be fixed properly in order to avoid fall-out caused by axial force.

MJSF and MJSFL with thicker casing are for higher pressure.

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.
* pipes of different material can be connected by coupling as long as they have same outside diameter

Product Characteristics

* Assembly type saves work time.
* Applicable to various pipe materials. Even connects pipe of 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 at one side. It enables products to be stored or work to be done at a narrow area.
* Stainless steel design is much lighter than cast iron product and reduces load on pipes.
* Grip type couplings resist against axial movement.
* Slip (flexible) type couplings allow pipe expansion and contraction.
* Repair clamps provide semi-permanent repair with speed and no down time.
* Couplings can be assembled and disassembled several times.
