HDPE Lower-pressure Condenser Cylinder Pipe Fittings
***Gas condensate tank:
The use of a condensate tank: laying of gas pipelines, the lowest point in the pipeline slope of not less than three thousandths of a gas condensate tank set up so that the water flows in the gas pipeline cylinder.
Two condensate tank advantages: The utility model is widely used in medium pressure gas pipeline, which
can save a lot of manpower, material resources, and the simple structure, low cost, high reliability,
self-draining, do not leak, safe.
Three condensate tank installation: 1, the product before installation, according to the design requirements have been pumping fluid and the external surface of the tube with the level of corrosion. 2, gas condensate tank according to the actual situation must be installed at the lowest point where the pipe segment. 3, cylinder head gas condensate wells should be installed in a central location condensate tank, the outlet valve installation position should be reasonable and should have sufficient space for operation and maintenance.

***HDPE Electro fusion condenser cylinder pipe fittings features:
1 applies to the same material of the pipe connections;
2 reliable connectivity, high seam strength, air tightness, weldability and stable;
3 injection molding, perfect structure, more secure, reliable, and inexpensive;
4 less susceptible to temperature changes and the impact of human factors;
5 welding process is simple to operate and easy to control, easy construction;
6. Investment in equipment, maintenance costs low.
***HDPE electrofusion condenser cylinder pipe fittings function:
Flange connections are the two pipes, fittings or pipes, the first one on each flange is fixed
between two flanges, with flange gasket, bolted together to complete the connection. Some fittings
and equipment have been built flange, also belong to the flange connection. Apply greater pressure
piping systems, with a steel flange fastened outside.
