The spacing and location of the pipeline support piers are improper, and even the form of dry bricks is used. Consequences: The pipeline suffered damage during the process of backfilling and tamping due to unstable support, causing rework and repair. Measures: The pipeline shall not be buried in frozen soil and untreated loose soil. The spacing of the buttresses must meet the requirements of the construction specification, and the support pads must be firm, especially the pipe joints, and should not bear shearing force. Brick buttresses should be built with cement mortar to ensure integrity and firmness. DIN F5 Gate Valve Taboo 2: The material of the expansion bolts for fixing the pipe bracket is poor, the hole diameter of the expansion bolts is too large, or the expansion bolts are installed on the brick wall or even the light wall. Consequences: The pipe ...

  As a   Butterfly Valve Supplier , share with you. The butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy and fast to operate, but also has good flow regulation and closing and sealing characteristics at the same time. It has been developed in the past ten years. One of the fastest valve varieties. The use of butterfly valves is very extensive. The variety and quantity of its use continues to expand, and is developing towards high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level. Butterfly Valve With the application of chemically resistant s...

  As a   Butterfly Valve Supplier , share with you. Common error The rubber elastomer in the butterfly valve will tear, wear, aging, perforate or even fall off during continuous use. The traditional thermal vulcanization process is difficult to meet the needs of on-site repair. Special equipment must be used for repair, which consumes a lot of heat and electricity, which is time-consuming and labor-intensive. Nowadays, the method of polymer composite materials is gradually used to replace the traditional methods, and the most applied one is the Fuschlan technology system. The superior adhesion and excellent anti-wear and tear-resistant properties of its products ensure that the service life of the new component is reached or exceeded after repair, and the downtime is greatly reduced. Butterfly Valve Installation and maintenance 1. During installation, the valve disc should be stopped in the closed position. 2. The opening position should be determined according to the rotation...
