Plastic-lined composite pipe, also known as steel-plastic composite pipe, embedded steel-plastic composite pipe with inner reinforcement, is divided into cold water pipe and hot water pipe. Because of its oxygen barrier effect, it can be directly used in direct drinking water projects, and its inner and outer layers are made of plastic material, which has very good corrosion resistance. Widely used in oil and natural gas transportation, industrial and mining pipes, drinking water pipes, drainage pipes and other fields.

Galvanized steel pipe, also known as hot-dip galvanized steel pipe, is a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the surface, which can enhance the corrosion resistance of the steel pipe and improve the reuse rate of the steel pipe. Galvanized steel pipes can be used as line pipes for general low-pressure fluids such as water and gas, petroleum industry, trestle pipe piles, support pipes for mine tunnels, etc.

Grooved pipe fittings are also called clamp connections, which can be either exposed or buried, that is, steel joints and flexible joints. Grooved pipe fittings include two categories: one is the pipe fittings that play the role of connection and sealing, including rigid joints, flexible joints, mechanical tee and grooved flanges; the other is that the pipe fittings that play the role of connection transition include elbows, three pass, cross, reducer, blind plate, etc.

Plastic-coated composite pipe: also known as plastic-coated pipe, plastic-coated steel pipe, and steel-plastic composite pipe, it is a new type of pipe material. It is based on welded steel pipe and seamless steel pipe, and the inner and outer walls are coated with epoxy resin or polyethylene. Powder, with anti-corrosion and corrosion resistance, is a non-toxic, non-radiation green and environmental protection pipe, which is widely used in various fluid transportation.

Fire-fighting metal hose is an important component in the connection pipeline of modern industrial equipment. Metal hoses are used as wires, cables, wire and cable protection tubes for automated instrumentation signals and civilian shower hoses, with specifications ranging from 3mm to 150mm. Mainly used for sensing circuit protection of precision optical ruler and industrial sensor circuit protection.

Pipeline prefabrication, pipeline design, prefabrication management, pipeline cutting, pipeline groove processing, welding, logistics and anti-corrosion paint, pipeline flaw detection and other work in a fixed area. Pipeline engineering is divided into pipeline prefabrication, on-site prefabrication and on-site installation. Advantages of pipeline prefabrication: It is convenient to coordinate and control quality, progress and management in a fixed area, reduce the workload of on-site prefabrication and on-site installation, and greatly improve the installation, quality and progress of the entire project.

"Pressure" pipeline series products are widely used in fire sprinkler, central air conditioning, drinking water, gas, electric wire and other pipeline industries. Compared with traditional products, it can greatly improve the pressure resistance and durability, and can reduce costs and reduce the consumption of raw materials. consumption, leading the industry in energy conservation, emission reduction and technological innovation. It truly conforms to the development direction of "energy saving, low carbon and environmental protection" advocated by the state.

Stainless steel pipe is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

The seismic support is composed of anchors, reinforced hangers, seismic connecting components and seismic diagonal braces. It is a seismic support facility that is firmly connected to the building structure and takes seismic force as the main load. The function is to reduce the degree of earthquake damage, reduce and prevent the occurrence of secondary disasters as much as possible, so as to achieve the purpose of reducing casualties and property losses.

The wire trough, also known as the row wire trough, or the bridge, is an electrical appliance used to regulate the arrangement of wires such as power cords and data cables, and fix them on the ceiling or wall. The main types of metal trunking are: galvanized trunking, stainless steel trunking, stepped trunking, aluminum alloy trunking, etc.
