What role does Sino French play in the waterproof casing pipe?
With different thickness and the use of different bolt pumps and valves, and pipeline connection, these equipment locally, also made the corresponding flange shape, also known as the flange connection. In two planes in the surrounding the use of bolts with closed connecting parts, generally referred to as "flange".
Such as ventilation pipeline connection, the parts can be called "flange parts." but this is only a partial connection of a device, such as a connecting flange and a water pump, the pump is not called "flange type parts" relatively small. Such as valves, etc., can be called flange parts
In the waterproof casing pipe engineering, mainly used for pipeline flange connection. The need to connect the pipe, flange mounted with a low-pressure pipe can use wire connecting flange, the use of more than 4 kilograms of pressure welding flange. Between the two flange and seal, and then fastened by a bolt flange with different pressure.
