Stainless steel hydraulic fittings using flat mouth articulation of the pipe quality requirements, the drainage of cast iron pipe oval degree of outer diameter, wall thickness and rubber stainless steel hydraulic fittings installation considerations of the physical function of the rubber ring have high requirements, due to the flat mouth of the watertight function of the premise of the poor, and therefore, in addition to the strict control of the pipe and fittings and so on the quality of the body outside, the high-pressure flange should also pay special attention to the maintenance of the port of the pipe and the fittings, butt-welded elbows to wrap the pipe The oval degree and flatness of the port. In the installation of the construction should be strictly in accordance with the operating procedures. Stamping elbow special in the straight pipe installation of each pipe interface with the riser card to be fixed in the construction of the load-bearing wall; cross-pipe at each interface should be added hangers, in the connection of sanitary appliances more concentrated toilet and bathroom, if the cross-branch pipe connecting sanitary ware on the two interfaces at intervals of not more than 600mm, you can set up a hanger in the centre.
