PE steel belt reinforced spiral corrugated pipe should be paid attention to when connecting with inspection well
PE steel belt reinforced spiral corrugated pipe is made of high-density polyethylene (PE). The steel strip with surface coated with adhesive resin is formed into a waveform as the main support structure, and the polyethylene material is wound into a whole double-wall spiral corrugated pipe. It has the characteristics of high ring stiffness, light weight, strong corrosion resistance, simple and reliable installation, good sealing performance, etc. It can be widely used in gravity self-flow transportation of various corrosive and non-corrosive media, and has broad market prospects.
PE steel belt reinforced spiral bellows can be connected by means of hot melt extrusion welding, heat shrinkable tube (belt) connection, clamp connection and fused tape connection. If necessary, you can combine the two connection methods.
PE steel belt reinforced spiral corrugated pipe should pay attention to the following points when connecting with the inspection well:
1. When the PE steel belt reinforced spiral bellows pipe and the inspection well are directly connected by brick or concrete, an interposer may be used. The intermediate layer of the pipe and the inspection well shall be preliminarily made of the same plastic binder and coarse sand as the pipe, and then cement mortar shall be built into the well wall of the inspection well.
2. PE steel belt reinforced spiral corrugated pipe connection with inspection well, need to use flexible interface, can also be connected with socket pipe fittings, according to the specific situation, it is determined by planning, check the bottom of the well bottom, should be steep with the bottom layer of the pipeline Pick up.
3. PE steel belt reinforced spiral corrugated pipe should be connected with the inspection well by means of short pipe connection when it is in soft soil foundation or low sloping, moor and high groundwater level.
The above points are the key issues in the connection process of PE steel belt reinforced spiral corrugated pipe. I hope users will pay attention to it.
