Item specifice
PVC-UH water supply pipe is made by improving the molecular chain structure of PVC, so that the product has high strength, high pressure, ring rigidity, good internal and external pressure, suitable for paving in the pipe gallery, good toughness and high modulus. It has small shrinkage, more than 45% of ring flexible energy, good impact resistance, suitable for material stress release caused by temperature changes in the pipe gallery; built-in plastic inspection well with high pressure sealing performance to ensure piping system Sealing; easy to install and fast maintenance, low maintenance cost; pipeline system design life ≥ 50 years, with the advantages of low investment and high cost performance.
PVC-UH pipe outer diameter range: dn20mm~dn1600mm, pressure rating: 0.63MPa~2.5MPa. The standard length of the pipes is 6 meters, 9 meters, 12 meters, and the colors are blue .
The pipe connection method is divided into solvent-adhesive type, elastic sealing ring type and integral apron connection. It can also be connected to other types of pipes such as cast iron pipes by flanges or other suitable adapters.

- Q:What's the smell of petrol in the car and the trunk?! Especially after a long drive!
- Leaks sometimes occur at the interface of the gasoline pipe, and then gasoline fumes may enter the vehicle through the air-conditioning system. If gasoline is found in the car, check the interface of the fuel line. It's easy to see just open the hood. Because once the leakage occurs, a long time will appear in the surface of a layer of sludge. This problem is also good to solve, as long as the interface is tightened or repaired, just OK!
- Q:Do I need a shim for the flat metal hose joint?
- If the two connections are flat, they must be placed gaskets, usually with PTFE gasket.
- Q:What's the difference between a vulcanized rubber tube and an intake manifold?
- The inlet is the passage of air into the engine block, which leads to the cylinder. The valve is mainly composed of a channel designed on the cylinder head, and the inlet is controlled by an air inlet valve at the end of the air inlet
- Q:High pressure hose crimping connector, pressed on what position can effectively prevent the head off?
- About the rubber tube assembly aspect books, at present only has the standard, the standard and so on, mainly is uses in the examination. Guide books are not withheld, but specializing in the production of rubber hose, a company has a lot of internal information, know people could get.
- Q:What are the matters that should be paid attention to when installing rubber hose joint in water pump?
- Know the rubber pipe joint is also called rubber joints, with vibration and noise reduction effect in the pipeline, and if used in water pump, so its main function is to prevent the suction flat and bear short time pressure, avoid water pump power and vibration and suction pipe bottom swing, the uniform flow and promotion in addition, the pump power consumption is reduced, because the rubber joint wall vertical groove, and prevent the vortex pump water, thereby improving the efficiency of water pump.
- Q:Method for inserting glass tube into rubber tube when assembling instrument
- If the outer diameter of the two glass tube to be connected is greatly different, the method can be used repeatedly to connect the glass tube into a channel or to be connected by a socket inserting method.In addition to the use of rubber sheathed outside the glass tube, can also be used for plastic pipe glass tube is sheathed, however, due to the elastic rubber pipe plastic pipe as well, so for sheathing plastic pipe with small diameter should be equal to the outer diameter of the glass tube.In addition, the use of plastic pipe sleeve glass tube should be adopted heat law, that is, the plastic pipe heating expansion and glass tube connection, and should not be rigidly inserted.Finally, because of the poor elasticity of the plastic tube, it is easy to age, harden and brittle, so when the glass pipe is connected with the plastic sleeve, the sealing measures must be adopted for the sleeve joint, and the sealing is usually done by gluing or waxing.
- Q:Hydraulic hose joint dimensions
- The maximum thread size is M60, but the maximum size is only 50.
- Q:Is the metal hose the same as the soft connection?
- One hundred and eight thousand in the metal hose and PVC casing, installation of on-line outside for protection, metal hose used in the instrument signal line, the soft connection is on the main circuit element used to protect the main loop stiffness damage loop, such as motor and pump connected with a soft connection,
- Q:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?
- Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate. Leak test: save 5min at 70% of the minimum blast pressure, and check again and again for leaks or damage. Due to the fact that water is often used in tests, the pressure and leakage pressure at normal temperatures may be slightly lower at normal temperatures.
- Q:Standard for implementation of type KXT-1 rubber joints
- It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into 5 kinds: single sphere, double sphere, different diameter body, bent sphere and wind pressure coil. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint.
