Description
Technical field
The present invention is specifically related to a kind of fuel gas polyethylene tube material.
Technical background
Plastic pipe is the chemical building material that high-tech is composited, and chemical building material is after steel, timber, cement, the 4th big class New Building Materials that the present age is emerging. Chemical building material achieves rapid progress fast development in China, especially the widely using of novel environment friendly plastics tubing, and has started the revolution that a sound substitutes traditional construction material. Plastic pipe, because having the advantages such as current loss little, energy-conservation, material-saving, protecting ecology, completion is convenient, is widely used in the fields such as building water supply and drainage, cities and towns plumbing and gas line, becoming the main force of new millennium urban construction pipe network.
Plastic pipe is compared with the pipelines such as traditional cast iron pipe, galvanized steel pipe, cement pipe, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance simplicity, long service life, it is widely used in construction industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and optical cable sheath, industrial fluids conveying, agricultural irrigation.
Plastics are different with traditional material, technical progress paces faster, the new technology that constantly occurs, novel material, novel process make plastics tubing more and more outstanding relative to the advantage of traditional material. Plastic pipe is compared with cement pipe with traditional metal tube, there is weight light, the 1/6-1/10 being generally only metal tube, has good erosion resistance, shock resistance and tensile strength, plastics tubing internal surface more smooth than cast iron pipe many, frictional coefficient is little, fluid resistance is little, can reduce water delivery energy consumption more than 5%, synthesis energy saving is good, manufactures the right reduction by 75% of energy consumption, convenient transportation, install simple, it may also be useful to the life-span reaches 30-50. Plastic pipe is very fast in countries in the world development, and developed country has accounted for absolute advantage plastic pipe and has not only been used in a large number replacing traditional steel pipe, cast iron pipe etc. in feedwater field and gas burning field application, and reason is just technological innovation. Material has great progress on the one hand; On the other hand utilisation technology has new development, makes traditional piping material not have competitive capacity being applicable to the occasion adopted in this way at all. Also have a lot of novel material, new technology to study, or found out on probation examine to, it is possible to certainly, the technical progress of 10 years plastics tubings from now on will impel plastics tubing to develop more rapidly, more extensively.
China's plastic conduit development is very fast, and quality is improving constantly. At present, begun to take shape with the plastics tubing industry of polyvinyl chloride (PVC-U) pipe, polyethylene (PE) pipe and polypropylene (PP-R) Guan Weizhu.Wherein polyethylene (PE) pipe is widely used in building water supply, construction drainage, buried drain pipe, building and heating, gas transmission and distribution, pneumatic tube, electrician and telecommunication protective casing, industrial pipe, agricultural pipe etc. due to the advantage of himself uniqueness. It is mainly used in Urban water supply, city gas supply and field irrigation. PE is polyethylene (english abbreviation of Polyethyleneofraisedtemperatureresistance), and the range of application of general PE tubing feedwater piping is the temperature lower than 40 DEG C, cannot be used for delivery pipeline. PE tubing is a kind of degree of crystallinity height, nonpolar thermoplastic resin. The milky appearance of former state HDPE, translucent in a certain degree in meagre cross section. PE has excellent resistance to great majority life and the characteristic of industrial chemical.
The production technology of China's type material falls behind, and most equipment all needs import, adds the impact of external enterprise so that manufacturing enterprise of China faces severe market test. But along with various novel material, new installation and novel process are constantly emerged in large numbers, towards diversification of varieties, customizations by impelling the plastic pipe of China and possess multi-functional plastic pipe direction and develop. Along with the further expansion of urban construction, polyethylene gas pipe also will be applied in more severe environment by further, the low temperature that such as continues, in acid or alkali environment, so needing the performance of further lifting PE gas line. Therefore carry out modification on its basis, exploitation high-performance, and meet the product of international standard, its use field can be expanded to a great extent.
