Q:What is PPS steel plastic composite pipe?
The product has the following advantages.1, retains the traditional metal pipe steel and strength, far better than plastic pipes, aluminum pipe;2. The utility model has the advantages of smooth inner wall, small frictional resistance and no fouling, and the outer wall is more beautiful and luxurious;3, light weight, toughness, impact resistance, high compressive strength, applicable temperature is wider, -30 DEG C to 100 DEG c;4, and the pipe can be connected by means of wire cutter, socket, flange, welding groove, etc., a variety of ways, and labor;5, and the pipe fittings connecting parts, thermal expansion coefficient is small, more safe and reliable;6, the price performance ratio is reasonable, comprehensive cost is low, more economical than copper tube and stainless steel tube.
Q:Ceramic composite tube and bimetal composite pipe
Double metal complex steel pipe lined with wear-resistant cast iron, corrosion characteristic of the product has not only high alloy cast iron (wear resistance, wear resistance and corrosion resistance than 16Mn seamless steel pipe is improved more than 30 times), and the impact properties of high mechanical strength and high, double metal composite is metallurgical combination, the use of safe and reliable.
Q:What are the main applications of bimetal composite pipes?
Industrial fields: oil and gas gathering pipelines, oil and gas well casings, sewage reinjection pipelines, chemical heat exchanger tubes, electric desalting water, desulfurization pipelines and so on. Metallurgy, desalination, pharmaceutical, chemical, wastewater treatment, new energy, food processing and other industries.
Q:What is the KPS composite pipe?
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:Plastic lined steel pipe is not plastic steel composite pipe?
Lining plastic pipe is a steel plastic composite pipe composite pipe, steel plastic composite pipe is a general term, divided into plastic lined steel pipe, plastic pipe, steel plastic composite pipe, PSP double wall corrugated pipe, steel wire mesh, steel plastic composite pipe can be called
Q:When will the PSP steel plastic composite pipe be of type G connection?
Internal expansion (G type) applies to DN25--DN110 specifications of plastic steel composite pressure pipe, exposed, buried and buried water pipe system, nominal pressure is not greater than 1.6Mpa, the transmission medium temperature is less than 40 degrees Celsius occasions
Q:PE pipe and steel plastic composite pipe how connected together
Electric melting sleeve, PE connection part of PE pipe and the steel tube with PE
Q:The difference between various kinds of steel plastic composite pipes
Steel plastic composite pipe generally refers to the plastic material in the inside tube, steel profiles, the main emphasis on the appearance or environmental requirements (such as static) high places, but for the strength and have certain requirements.
Q:PSP plastic steel composite pipe and lining plastic pipe are not the same kind of pipe?
PSP steel plastic composite pipe: P is PE or PPR and PERT S is referred to as material, steel pipe is referred to as PSP, inside and outside the plastic intermediate steel composite, PSP steel plastic composite pressure pipe, steel wire mesh, and PE coated steel mesh steel plastic pipe, steel plastic pipe,
Q:What is the difference between the PPR aluminium plastic composite pipe and the steady pipe?,
Aluminum plastic composite pipe has good insulation properties, both inside and outside the wall is not easy to corrosion, because the inner wall smooth, fluid resistance is small; and because can be bent, so to facilitate the installation of construction. As the water supply pipe, aluminum-plastic composite pipe has sufficient strength, but if too much lateral force, will affect the strength, so appropriate for tube or buried in the wall construction, but should not be buried underground. (aluminum-plastic composite pipe can also be buried in the ground, such as a pipe for one, aluminum-plastic composite pipe) aluminum-plastic composite pipe connection is card sleeve (also card type), so the construction is going through a stringent test pressure, test connection is solid. The two is to prevent the regular vibration, the card sets loose. The three is the length of the installation should be sufficient, so as not to pull off.
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.
