The price of the double-wall bellows has been Shared with you. Today, I will share the interface connection problem of the double-wall bellows with you. I hope it will be helpful to the friends in need.
The double wall bellows is a new kind of light tube made of high density polyethylene. The price of double wall bellows is characterized by light weight, high pressure resistance, good toughness, fast construction and long service life. Its excellent wall structure design, compared with other structures of the pipe, the cost is greatly reduced. And because of its convenient and reliable connection, it has been widely used at home and abroad. Large number of replacements for concrete pipes and cast iron pipes. So how do you connect the HDPE double wall bellows?
The socket tube shall be installed with the socket along the flow direction, and the double wall corrugated tube tube shall be installed from upstream to upstream along the downstream direction. Pipelines shall be in a straight line, and the allowable rotation Angle of the two adjacent pipelines' axes shall generally be no more than 2 degrees. In order to prevent the position movement of the pipe axis arranged when the joint is closed, pipeline stabilization measures must be taken. The bag can be filled with sand, sealed and pressed at the top of the pipe, depending on the diameter of the pipe. After the pipe is connected, the depth and axis at the bottom of the pipe should be checked to make it conform to the requirements. If there is displacement, suspension or pull out, rework is required.
The rubber mounting position of the double wall bellows shall be in the groove between the second and third waves of the socket. The price of double walled bellows depends on the design requirements. When using two sealing rings, it is recommended to separate the rings into one ripple. Clean the inner and outer surfaces of the socket before connecting, place a sealing ring on the socket, and apply lubricant (usually soapy water) on the working surface of the socket and the surface of the rubber ring. The insertion direction is the direction of the water flow. For the centerline of a quasi socket, use manual labor or a wooden baffle to slowly insert the installed pipe into the socket at the bottom. Upon completion of the connection, immediately fill the double wall bellows with the same soil quality to fill the reserved slots.
