1\The composition of P-LOC:
High pressure self-energized flange, also called clamp connector or P-LOC, is new connection way of high pressure pipelines. P-LOC contains 4 parts: 2 HUBs, 1 metal seal ring, 1 pair clamps, 4 sets of bolts and nuts.
2\Seal ring’s function:
P-LOC seal ring looks small, but it is the key element of a clamp connector. The design and making of seal ring counts much for clamp connector’s sealing. The seal ring is a “T” in cross section.
The leg of the “T” forms a rib that is held by the hub faces as the connection is made.
The two arms form lip seals that create an area of sealing surface with the inner surface of the hub.
The clamp fits over the two hubs and forces them against the seal ring rib.
3\Seal ring material:
As the seal ring is the most important part of a clamp connector, we are strict and discreet in choosing seal ring material. We learn about customers’ working conditions, such as: Temperature, pressure, pipe size, pipe material and medium. Usually, we have 35CrMoA, A564-630, A638, 4140, A182-F55, etc. In a word, we design and making according to customers’ working condition. Anything we do is for customers’ requirement.
