It is Shanghai Yuanzhou Youmai PVC-C fire pipe, which many people are accustomed to calling CPVC pipe for fire protection, which is allowed to be used by national fire regulations. CPVC is a general term for chlorinated polyvinyl chloride plastic pipes, which were mainly used for civil water supply and power casing in the past. After 2018, CPVC can be applied to fire sprinkler, but because it is higher than the requirements of ordinary CPVC pressure resistance and fire resistance, the specification is clearly defined as PVC-C, and it needs to pass the type approval of relevant national departments.

1. Ductile ink water supply cast iron pipe:
The pipe made by using cast iron above No. 18 after adding nodularizing agent and centrifugal casting at high speed by centrifugal ductile iron machine is called "ductile iron pipe", referred to as ball tube, ductile iron pipe and ductile cast pipe.
2. Copper tube: Copper tube is also known as copper tube. A type of non-ferrous metal pipe, which is a seamless pipe that is pressed and drawn. Copper pipes are strong and corrosion-resistant, and have become the basis for modern contractors in the installation of water, heating and cooling pipes in residential commercial buildings.
3. Alloy pipe:
Alloy pipe is a kind of seamless steel pipe, and its performance is much higher than that of general seamless steel pipe, because this kind of steel pipe contains more CR, and its high temperature resistance, low temperature resistance, and corrosion resistance are not comparable to other seamless steel pipes, so alloy pipes are widely used in petroleum, aerospace, chemical industry, electric power, boilers, military and other industries.
4. Composite pipes:
Composite pipe is a pipe composed of two or more materials, which is based on metal pipe, and is formed by welding polyethylene, cross-linked polyethylene and other non-metallic materials inside and outside, which has the advantages of metal pipe and non-metallic pipe.
5. Plastic pipes:
As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection and low consumption, mainly including UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene (PE) water supply pipes.

Fire pipe fittings refer to the metal link port on the fire pipe belt, as a special material made of products, its connection operation is very simple, without special professional skills, ordinary workers can operate through a brief training. On the other hand, the performance of fire pipe fittings in many aspects such as connection sealing and compression resistance is relatively good.
1. At present, the fire trench pipe fittings produced in China can be divided into two categories:
1. The pipe fittings that play the role of connection and sealing include rigid joints, flexible joints, mechanical tees and grooved flanges;
2. The pipe fittings that play the role of connection transition include elbows, tees, crosses, reducers, blind plates, etc.
PS: There are three main parts of the fire trench pipe fittings that play the role of connecting the dense liquid seal: sealing rubber ring, clamp and locking bolt.
The rubber sealing ring located in the inner layer is placed on the outside of the connected pipe, and coincides with the pre-rolled groove, and then the clamp is fastened on the outside of the rubber ring, and then the object can be fastened with two bolts. Due to the unique sealable structure design of its rubber sealing ring and clamp, the groove connection has good sealing, and its sealing performance is correspondingly enhanced with the increase of fluid pressure in the pipe.
2. Introduction to several common fire pipe fittings:
1. Drainage and fire pipe fittings: ordinary drainage cast iron socket pipe and pipe fittings. Flexible anti-seismic interface drainage cast iron straight pipes, such cast iron pipes are sealed with rubber rings and bolted, and have excellent flexibility and elasticity under internal water pressure.
It can adapt to large axial displacement and transverse deflection deformation, and is suitable for indoor drainage pipes in high-rise buildings, which is very suitable for ground dynamic areas.
2. Cast iron pipe for water supply: mild, high-wall, thin-walled, pressure-resistant, impact-resistant, slag-resistant, corrosion-resistant, earthquake-resistant, etc. The pipe interface adopts a flexible interface, and there is also a certain elongation and deflection angle.
It has the advantages of pig iron pipe and steel pipe material, avoids the shortcomings of iron and steel, and has a high pressure bearing force for water cast iron pipe, which is suitable for the transportation of pressure fluids such as water and gas.
3. Sand centrifugal fire straight pipe: The raw material of sand centrifugal cast iron straight pipe is gray cast iron, which is suitable for the transportation of pressure fluids such as water and gas.
4. Continuous fire pipe: continuous fire pipe is a continuous fire pipe with gray mouth fire pipe, which is suitable for the transportation of pressure fluids such as water and gas.
The above is the classification introduction of common fire trench pipe fittings, I hope it will be helpful to you.

Fire hose is an important component of modern industrial equipment connection pipeline. Metal hoses are used as wire and cable protection pipes for wires, cables, automation instrument signals and civil shower hoses, with specifications from 3mm to 150mm. Small-diameter metal hose (inner diameter 3mm-25mm) is mainly used for the protection of the sensing circuit of the precision optical ruler and the protection of the industrial sensor line.
Because the main parts of the hose are made of austenitic stainless steel, so as to ensure the hose excellent temperature resistance and corrosion resistance, the hose has a wide range of working temperature, -196-600 degrees, the hose used according to the corrosiveness of the medium through the pipe to choose the applicable stainless steel grade, can ensure the corrosion resistance of the hose.
1. The whole metal hose is made of 1Cr18Ni9Ti stainless steel, which has strong corrosion resistance.
2. The hose body is a thin-walled stainless steel pipe body hydroformed, which has strong flexibility, elasticity, strong bending and vibration resistance, and the reinforced protection of the woven mesh sleeve makes it have higher pressure-bearing capacity.
3. The connection at both ends of the hose can also be made into other connection methods except for thread and flange standards, which is convenient for connection and use.
4. This product is not only suitable for matching with rotary joints, but also widely used for soft connections for the transportation of various fluid media.
Corrosion resistance, high temperature resistance, low temperature resistance (-196 +420), light weight, small size, good flexibility. It is widely used in aviation, aerospace, petroleum, chemical, metallurgy, electric power, papermaking, wood, textile, construction, medicine, food, tobacco, transportation and other industries.
1. Flexible hose between metal hose pitches, small bending radius.
2. The metal hose has good elasticity and no blockage or stiffness.
3. The metal hose unit is light in weight and has good caliber consistency.
4. The metal hose has good flexibility, repeated bending and flexibility.
Metal hoses. Metal hoses.
5. The metal hose has good corrosion resistance and high temperature resistance.
6. The metal hose is anti-rat bite and wear-resistant, and prevents the internal wires from being worn.
7. The metal hose has strong bending resistance, tensile resistance and side pressure resistance.
8. The metal hose is soft and smooth, easy to thread, install and position.
9. There are many hose joints supporting the metal hose, which is easy to connect with the instrument and equipment.
This depends on the diameter and wall thickness of the pipe you need to cut.
