Krah pipe is a new type of polymer material pipes, its main material is polyethylene, which has strong chemical properties. Krah pipe has been widely used in every occasions, but do you know the working principle of it? This passage will introduce the working method of krah pipe for you briefly.
The krah tube is a pipe formed by winding high-density polyethylene. In the manufacturing process, a hot winding forming process and a synchronous PE extrusion welding process are employed. The main material of the krah tube, polyethylene, has stable chemical properties, can be corroded when transporting materials, and has external pressure resistance. It is a pipe with special structure.
The specific production process of the krah pipe is: extruding the flat belt and the U-shaped belt in a molten state from the die of the extruder, uniformly winding on the heated drum mold at a predetermined position, and welding the flat belt in the structural design. The seam is covered by the U-shaped strip, which improves the overall resistance of the product to external pressure.
The krah pipe is pre-embedded with the same material in the Interface, and the pipe is connected by socket electrofusion technology. In essence, the interface material, the structure and the identity of the pipe body are ensured, and the integration of the joint and the pipe material is realized. Now the krah pipe connection technology is very mature, and it can be 100% leak-free during use.
Compared with the rubber ring type or other mechanical joints, the krah tube does not have the risk of leakage caused by the twisting of the joint, and the sealing performance is very good. This not only ensures the long service time of the pipeline system, but also ensures the safety of the pipeline operation.
Due to the same conditions of use, the krah tube has the characteristics of light weight, convenient transportation and construction compared with other pipes. Therefore, the transportation and installation costs can be effectively reduced, and the installation of the krah tube can effectively shorten the construction period.
Since the corrugated pipe can be directly applied without the concrete cushion and the concrete pipe foundation groove, the excavation and the lower pipe can be performed. Back-filling is done at the same time, which simplifies the construction process.
The whole krah pipe has good flexibility, and its partial pipe section also has strong resistance to external pressure. Therefore, it can be safely applied to roads with heavy loads, and safety can be guaranteed. Due to the flexibility of the pipe, the loss of pipeline damage can be minimized in the event of earthquakes, ground subsidence and other geological activities, improving the ability of earthquake resistance and disaster reduction.
Krah tubes are mainly used in municipal underground drainage, sewage, rainwater collection, water delivery, ventilation, etc. It can also be used as a seepage and drain pipe for railways, highways, golf courses, football fields, etc. Because polyethylene materials have excellent acid, alkali and corrosion resistance.
Krah tubes are also widely used in nuclear power, steel plants, power plants, petrochemicals, terminals, stations, etc., especially in tidal flats, saline-alkali land, submarine riverbeds, soft foundations. In the harsh environment such as expansive soil and seismic belt, the krah tube has outstanding advantages.
