1. Galvanized steel pipe: it is welded with hot dip coating or electrogalvanized coating on the surface. Cheap price, high mechanical strength, but easy to rust, tube wall easy to scale and bacteria, short service life. Galvanized steel pipe is widely used in electric power, railway vehicles, automobile industry, highway, construction, machinery, coal mine, chemical industry, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries. Common connection modes are threaded connection and flange connection.
2. Stainless steel pipe: this is a kind of more common pipe, divided into seam steel pipe and seamless steel pipe, its main characteristics are: corrosion resistance, impermeability, good air tightness, smooth wall, light weight, easy installation, high pressure resistance, but expensive. Mainly widely used in food, light industry, petroleum, chemical, medical, mechanical instruments and other industrial pipeline and mechanical structure components. The commonly used connection modes include compression type, flexible connection type, push type, push thread type, socket welded type, flexible flange connection type, threaded pipe connector connection type, welded type and the derived series of welding and traditional connection type.
3. Lined with stainless steel pipe: with thin-walled stainless steel lining, on the inner wall of the steel pipe, composite thin-walled stainless steel tube, with the base pipe lined with stainless steel tube tight knot, that is lined with stainless steel clad pipe, its advantages can be welded, scaling, nodules, corrosion resistance, high temperature resistant, faults for high prices, high technical requirements, material strength is hard. Widely used in cold and hot water pipe, industry, food chemical plant stock liquid, fluid transport and other fields. There are many types of main connections, such as welding, flanged, grooved, threaded and pipe connector connections.
4. Copper pipe: also known as copper pipe, metal pipe with color, is pressed and drawn seamless pipe, copper pipe has corrosion resistance, bacteria, light weight, good thermal conductivity, the disadvantage is high cost, high construction requirements, thin wall, easy to touch. Copper pipe is widely used in the field of heat transfer, such as hot water pipe, condenser and so on. The main connection of copper pipe is threaded connection, welding, flange connection, special pipe fitting connection and so on.
5. Fiberglass Reinforced Plastic Pipe: Fiberglass Reinforced Plastic Pipe is also known as glass fiber wound sand pipe (RPM pipe). It mainly uses glass fiber and its products as reinforcement materials, unsaturated polyester resin and epoxy resin with high molecular components as basic materials, and inorganic non-metallic particle materials such as quartz sand and calcium carbonate as fillers as main raw materials. Its advantages are good corrosion resistance, aging resistance, heat resistance, frost resistance, light weight, high strength, good wear resistance, shortcomings for brittle, poor wear resistance. Commonly used in hardware tools, garden tools, alkali resistance and corrosion engineering, machinery, chemical industry and other fields. The main connection modes are double socket casing joint, flexible rigid joint, socket and socket joint, flange and so on.
6. PVC pipe: PVC is also known as polyvinyl chloride, PVC can be divided into soft PVC and hard PVC, soft PVC is generally used in the floor, ceiling and leather surface, but because soft PVC contains plasticizer, poor physical properties (such as water pipe need to bear a certain pressure, soft PVC is not suitable for use), so its range of use is limited. Hard PVC does not contain plasticizer, so it is easy to form and has good physical properties, so it has great development and application value. Used in all kinds of panel surface layer of packaging, so also known as decorative film, with film, widely used in building materials, packaging, pharmaceutical and other industries, its characteristic is green environmental protection, reduce water, acid and alkali erosion, inner diameter is smooth, easy construction, disadvantages for should not be used for hot water pipe, low-quality counterfeit have pollution, impact brittle crack. The main connection modes are flange connection, welding, socket bonding, thread connection, non-metallic pipe connector connection.
7. HDPE pipe: HDPE is a kind of high crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. HDPE tube must bear a certain pressure, usually choose a large molecular weight, good mechanical properties of PE resin, such as HDPE resin. The strength is 9 times that of ordinary polyethylene pipe (PE pipe); HDPE pipeline is mainly used for: municipal engineering water supply system, building indoor water supply system, outdoor buried water supply system and residential area, factory buried water supply system, old pipeline repair, water treatment engineering pipeline system, garden, irrigation and other fields of industrial water pipe. Medium density polyethylene pipe is only suitable for conveying gaseous artificial gas, natural gas, liquefied petroleum gas. Low-density polyethylene tubing is a hose.
8. PP-R pipe：PP-R pipe and three type polypropylene pipe, is currently the Z applied in domestic outfit project is much of a water supply pipe, a heat preservation and energy saving, health, non-toxic, light weight, corrosion resistance, fouling, long life and other advantages, its disadvantages in connection of randomness, there is a risk of cracking, good low temperature resistance is poor, expansion coefficient is larger, aging resistance is poor. PP-R pipe is widely used in urban gas, building water supply and drainage, industrial fluid transport, urban and rural water supply and drainage, agricultural irrigation and other construction, power and cable sheath, municipal, industrial and agricultural fields. The common connection mode is hot melt connection, wire connection, special flange connection
9. Aluminum-plastic composite pipe: aluminum-plastic composite pipe is the earliest replacement of cast iron pipe supply pipe, its basic composition should be five layers, namely from the inside out, plastic, hot melt glue, aluminum alloy, hot melt glue, plastic. Aluminum-plastic composite pipe has better thermal insulation performance, the inner and outer wall is not easy to corrosion, because the inner wall is smooth, the resistance to fluid is small; And because it can be bent at will, it is convenient to install and construct. As a water supply pipeline, long-term thermal expansion and contraction are easy to leak, will harden maintenance inconvenience. It is used in hot and cold water piping system, indoor gas piping system, solar air conditioning piping system.
