For the purpose of fast and easy mounting of the metal pipelines for any purpose, muff couplings are used. They are a system of a case, a sealing cuff, and a locking device. All these elements except the seal are made of stainless steel.
The couplings are set on the fixed pipes, at tightening the locking device due to threaded parts screwing together, case diameter reducing, and the sealing element pressing to the pipe surface take place.
Such systems are also getting widely spread at repairing pipelines, what sealing the damaged areas that have appeared in process of operating the parts.
The muff couplings effectively substitute flanged joints and weld connections not giving way to them on operational reliability.
In process of the locking device tightening, a great deal of scores is forming on the studs thread turns made of stainless steel. This happens because of seizure of the parts surfaces in process of tightening.
In order to provide simple and quality mounting of the muff coupling, MODENGY 1001 anti-friction solid-film coating is applied onto the locking device studs.
It fits great for treating the parts made of stainless steel. A thin layer of the product insulates thread turns surfaces excluding their direct contact and seizure.
Due to this, scuffing forming is excluded, the issue of parts seizure in process of tightening is solved, mounting process gets easier, and possibility of multiple assemblies and disassembles of the muff coupling is provided.
MODENGY 1001 coating is easy to be applied out of an aerosol can, and it get cured at room temperature withing just 15 minutes what enables to use this product in the field.
Use of the anti-friction solid-film coating contributes to cutting down the time expenses for mounting and dismantling the couplings, to improving quality of assembly, and to extending service lifetime of the threaded connections made of stainless steel.
