Q:What's the difference between the steel wire mesh composite pipe and the steel skeleton plastic composite pipe?
Steel skeleton plastic composite pipe: steel mesh welding and plastic extrusion simultaneously, the pipe wall inside and outside the plastic layer through the metal mesh tube wall in the middle of the connection as a whole, no obvious interface between steel and plastic, the overall structure is similar to that of reinforced concrete, two kinds of composite material completely as a whole, stable and uniform quality, each part of the pipe. There is no delamination hazard.
Q:Is the PSP plastic steel composite pipe high in pressure?
Shenzhen Hainiu steel plastic composite pipe is a new type of metal and plastic composite pipe, welded steel pipe for the middle layer, the inner layer and the outer layer of polyethylene plastic, using special hot melt extrusion molding method, through the integrated pipe.
Q:Fire special steel plastic composite pipe is lined with plastic or plastic
Steel and plastic composite steel pipe, the product is seamless steel pipe, welded steel pipe as the base pipe, painted with high adhesion, corrosion protection, food grade sanitary powder coating or epoxy resin coating. By pretreatment, preheating, internal coating, leveling, postprocessing technology made in water supply galvanized plastic composite pipe, is the upgrading of traditional galvanized pipe. Product implementation of the Ministry of construction CJT120-2000 industry standards. Caliber range DN15--DN1200 with flange and pressure trough, coating length 6m, 9m, 12m and variable length, coating wall thickness of 100 microns to 500 microns, usually 350 microns.
Q:What is the actual current direction of the composite tube?
Composite tube: in a shell of an electron tube, there are more than two electrode systems, each electrode system independently through the electronic flow to achieve their respective functions, this tube is called a composite tube. A composite tube is a combination of two or more transistors in accordance with a certain law, which is equivalent to a triode, and the compound tube is also called a Darlington tube
Q:What is the thermal fuse sleeve of the wire mesh plastic composite pipe?
Hot melt connection quota of plastic pipe.
Q:What are the advantages and disadvantages of PE composite pipes for water supply?
PE composite pipes have a wide range of standards.Simply put: CJ/T 123124, water supply steel skeleton, polyethylene plastic composite pipeAdvantage:1, pipes, pipe fittings have reinforced skeleton. Pipe is welded steel wire, pipe is punched steel plate. (other standard pipe fittings are made of pure PE pipe fittings)2, and PE ratio, good anti cracking performance. It includes: slow crack growth and rapid crack cracking.3 and CJ/T 123, the standard is nominal internal diameter. With the valve, instrument, through the national standard flange matching, convenient and quick.The advantages and disadvantages of other equivalent PE pipe line.
Q:PP-R is it a steel pipe, a plastic composite pipe, or a cast iron pipe?
The formal name is the random polypropylene pipe, which is made of random copolymerized polypropylene, so it is a plastic pipe
Q:Aluminum alloy lining plastic PPR composite pipe performance advantages?
Aluminum alloy lined plastic PPR composite tube pressure resistance, anti-aging: not only gorgeous appearance, but more importantly, it can effectively resist ultraviolet radiation in the sun, anti-aging, enhanced pipe service life, suitable for Ming zhuang. 2. linear expansion coefficient, longitudinal shrinkage rate low 3. excellent oxygen impermeable performance of 4. easy to install 5. scope: powerful functions used in the building hot and cold water supply piping system suitable for heating and air-conditioning supply and return water pipe system is applicable to all kinds of food hygiene, drinking water and medicine preparation pipeline system is applicable to all kinds of chemical agents, the air pressure pipeline system... 6.... Free maintenance: stable flow - the inner wall is smooth, no scaling, small transmission resistance and stable flow. Heat preservation and energy saving - low heat transfer rate, heat insulation, energy saving effect 7., applicable to domestic hot and cold water, natural gas pipeline, air conditioning pipe
Q:Plastic steel composite pipe buried pipe how to connect?
Steel plastic composite pipe, seamless steel pipe, welded steel pipe as the base pipe, painted with high adhesion, corrosion protection, food grade hygiene type polyethylene powder coating or epoxy resin coating. By pretreatment, preheating, internal coating, leveling, postprocessing technology made in water supply galvanized plastic composite pipe, is the upgrading of traditional galvanized pipe.
Q:Construction technology of PE steel plastic composite pipe
1. before installation, check the groove to meet the installation requirements, and then check the appearance of the pipe there is no obvious sag, cracks, scratches, scratches, found quality problems, timely replacement.In 2., three links, elbow, reducer etc. fire hydrant with C20 concrete concrete pier, brick pier reinforcement flange valve.3. PE water supply pipe and metal pipe, valve, fire hydrant connection, must use plastic steel transition joint or special flange connection.4. the exhaust valve shall be installed at the uplift part of the pipeline or on the uphill side to reduce the impact of the water pressure on the pipe. The ratio of the pipe and exhaust valve is designed to be 1:8.5. because the PE pipe itself has good flexibility and flexibility, all pipe installation has not considered the installation of expansion joint.
The company products are strictly produced as the standard of international, country and industry etc. And has already passed the test of national, provincial, municipal and other authority departments testing. Since the products put on the market, we own a good name in china and abroad.The products range has been changed from single into series. Now the company has become a high-tech modern enterprise of scientific research, development, production, marketing, trade and services.
