Water Supply Pipe Series
The double-flat wall steel-plastic composite winding drainage pipe developed and produced recently by Jingzhou Liangcheng Science and Technology Co., Ltd. is prefabricated into "T" type plate belt with high density polyethylene (HDPE) as the main raw material. The plate belt is wound on the pipe forming machine and welded into a pipe. At the same time, the W-type steel belt bound by galvanized steel belt is embedded in the groove between the two plates, and PE is coated on the steel belt to become the third generation of new steel-plastic drainage pipe on the outer wall of the pipe.
Liangcheng steel-plastic composite pipe, which is based on seamless steel pipe and welded steel pipe, is coated with polyethylene powder coating or epoxy resin coating with high adhesion, anti-corrosion and food-grade sanitation on the inner wall. The water supply galvanized and plastic-coated composite steel pipe made by pre-treatment, preheating, internal coating, leveling and post-treatment process is an upgraded product of the traditional galvanized pipe, and the steel-plastic composite pipe is generally connected with threads.
PPR cold water pipe is formed by injection molding of random copolymerized polypropylene. PP-R is a new generation of pipe material, which is made by random and uniform polymerization (random copolymerization) in the molecular chain of about 5% of PP through the gas phase copolymerization process in the late 1980s. With its non-toxic, durable, easy installation and other characteristics, Liangcheng PPR pipe is widely used in cold water pipes in engineering, water conservancy, industry and other fields.
Cold-formed metal corrugated culvert pipes include hot-dip galvanized spiral corrugated steel pipes and plastic-coated hot-dip galvanized spiral corrugated pipes, which are referred to as "threaded steel pipes" for short. The scope of application and engineering field are in accordance with CJ/T431-2013 Threaded Steel Pipes for Drainage. This standard is applicable to the plastic-coated threaded steel pipes used in non-pressure buried urban drainage, industrial drainage and other projects with the transmission medium temperature below 45 ℃, as well as the drainage and collection of urban rainwater Galvanized threaded steel pipe used in farmland water transmission and other projects.
PPR pipe is a new generation of environmental protection products. In addition to the advantages of general plastic pipe quality, corrosion resistance, non-scaling and long service life, PPR pipe also has good sanitary performance, good heat resistance, low thermal conductivity, thermal insulation and energy conservation. It adopts hot-melt connection, easy installation, reliable connection, and recyclable materials. It is a veritable green environmental protection building material.
PE double-layer composite pipe for water supply is produced by our company using polymer co-extrusion technology and fully fusing the two materials in the composite pipe production line. It has the property of climbing PE pipe and better sanitary performance. The color and appearance are the same as PE water supply pipe, except that the inner wall of PE water supply double-layer composite pipe is pure white.
Product features: Long service life: under normal conditions, the service life is more than 50 years; Good hygiene: PE pipes are non-toxic, free of heavy metal additives, free from scaling and bacteria, and solve the secondary pollution of drinking water; Comply with GB/T17219 safety evaluation regulations: resistant to corrosion of various chemical media; No electrochemical corrosion; The inner wall is smooth, and the friction coefficient is very low. Compared with the steel pipe with the same inner diameter, the flow rate can be increased by "30%"; It has excellent wear resistance, which is 4 times of that of steel pipe; Good flexibility, high impact strength, strong shock resistance and distortion resistance; Light weight, convenient transportation and installation; The unique electric fusion welding, hot fusion butt welding and hot fusion insertion technology make the strength of the interface higher than that of the pipe body, ensuring the safety and reliability of the interface; The welding process is simple, the construction is convenient, and the comprehensive cost of the project is low.
