1.The Introduction Of HDPE Carat Pipe
Introduction: The carat tube is a hot-wound high-density polyethylene (HDPE) wound structure wall pipe. The wall pipe is made of high-density polyethylene resin as the main raw material, and it is made of hot-wound pop-type process with polypropylene (PP) single wall. The bellows is made of a support structure and is made of a special structural wall pipe having a high resistance to external pressure. Carat tube products can be divided into PR, OP, SQ, VW three series.
- The usage of Carat tube
Municipal water supply and drainage: At present, the internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is an ideal pipe for replacing the original drainage cast iron pipe and cement pipe of the city; it is used for municipal underground drainage and sewage discharge. Rainwater collection, water delivery, ventilation, etc.; used to discharge liquid and gaseous substances into rivers or seas.
Large-scale water conservancy projects: long-distance water transportation, farmland irrigation, siltation in the reservoir area, use of water source pipes, irrigation pipes and hydropower stations;
Environmental protection projects: Deep sea sewage, sewage treatment, garbage dumps, detoxification pipelines. Various structural wall structures and pipes of hot-structured wall-wound tubes, inspection wells, and pipe fittings can be used in advanced shallow drainage systems due to their reliable connection properties.
Oil industry: oil and gas pipelines.
Coal industry: coal transportation project and various ventilation systems.
Chemical Engineering: Chemical containers, especially corrosive fluid delivery pipes.
Power engineering: circulating water pipelines.
Road engineering: Crossing water culverts and crosswalks with large traffic loads such as roads and railways; used as seepage and drainage pipes for railways and highways; and methods for refinishing damaged pipelines by means of "pipe liners" more and more important.
Agricultural engineering: farmland, orchard, tea garden and forest belt drainage and so on.
Large airport ports and docks: Drainage, sewage pipes, etc. for large airport ports and dock projects.
Construction: rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
Communication tube: railway, highway communication, communication cable, cable protection tube.
Water storage system: a water storage system for intercepting slow water flow.
Special application: The hot-wound wall-wound tube can also be used for special purposes such as ventilation, passage, desert, marsh, fluid transportation in the lake area, etc.
