MJD 13~1000A / MJDL 15~1000A / MJDF, MJDFL 65~1000A

MJT, MJTL, MJTF, MJTFL 1100~1500A

MJF, MJFL, MJFF, MJFFL 1600~4000A

These are composed of two, three, or four separate pieces of the casing and lock part at each end. They have better tightening and a wider coupling range. It is easy to install even at large diameter pipes. Pipes need to be fixed properly to avoid fall-out caused by axial force if used for the connection.

MJDF, MJDFL / MJTF, MJTFL / MJFF, MJFFL 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 the same outside diameter

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.
