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.

"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.

Malleable iron, commonly known as malleable cast iron, is first cast into white cast iron castings, and then decomposed into flocculent graphite through malleable annealing to obtain malleable cast iron castings.

The fire valve is composed of three parts: the valve body, the opening and closing mechanism, and the valve cover. It is an important accessory for the control of industrial and construction pipelines. Mainly divided into butterfly valve, gate valve, alarm valve and so on.

Fire-fighting equipment refers to the automatic fire alarm system, indoor fire hydrant, outdoor fire hydrant, and other fixed facilities in the building. The categories of fire fighting equipment include automatic facilities, building facilities and sprinkler systems. It mainly includes sprinklers, reels, hoses, fire hydrants, etc.
