Q: Rubber soft joint, what brand of good, the best price is more reasonable. Don't say anything expensive.: The rubber joints produced throughout the country have the longest history in Shanghai, and have the characteristics of the type and sales volume of Gongyi city. They have been sold in the plumbing market all over the country

Q: Can the natural gas hose not exceed 1.5 meters or 2 meters?: The gas hose on the principle of not more than 1.2 meters, and regularly check the technical requirements, 1-2 must be replaced if the temporary gas can also be longer, if long-term use, as far as possible the use of metal pipe joint and the gas stove can also use metal hose, high safety factor.

Q: What is the essential difference between rubber expansion joint and rubber joint?: A rubber joint is a hollow rubber product used for flexible connections between metal pipes. The flexible joint is also called soft rubber pipe joints, rubber joints, soft rubber joints, flexible joints, high-pressure rubber joints, rubber shock absorber etc.. It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into single sphere, double sphere and curved sphere. 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. This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems.

Q: Difference between non-standard rubber joint and national standard rubber joint: Rubber joint national Ministry of water conservancy is standard CJ/T208-2005 documents of rubber joint standard, this paper has clear rules for the product, identify the products should meet the following characteristics: standard rubber joint extrusion is produced by the rotation of the screw, the glue is advancing, and with the help of the mouth, but the needs of various semi-finished extrusion the shape of the. The extrusion process is characterized by uniform and compact quality and easy conversion of semi-finished product specifications and section shapes. The extrusion process of the national standard rubber joint in the extruder is divided into two parts: one is the extrusion system used for pushing the rubber; the two is the die system, which is used to form the rubber to make a definite section shape. Therefore, in the process of pressing, the rubber layer is usually more than ten layers, and the rubber joint has the characteristics of compact structure and high pressure resistance.Non-standard rubber joint is in the national standard between substandard products and national standard products, often illegal businesses use to reduce the rubber joint, the number of layers to reduce the cost of rubber joints. Use non-standard products instead of GB products. Non-standard products in use process, because the arc bearing layer, rubber layer is insufficient, the strength drops, in the use process is easy because the pressure withstanding insufficient causes the pipe network to burst.

Q: What is the difference between plastic lined steel pipe and rubber lined steel pipe?: Weather resistance: the practice proves that the rubber in the harsh environment (instantaneous high temperature and direct sunlight, external strength) stable performance, so the lining hose has a strong weather resistance, weatherability and lining performance of plastic pipe as lining hose.

Q: The difference between silicone tube and PVC tube: Silicone hose is also a kind of rubber tube, resistant to oil and heat. Because of the different types of rubber rubber pipe has many applications, commonly used rubber tube material EPDM, CR, VMQ, FKM, IIR, ACM, AEM, common structure with single, double, multilayer, enhanced, non enhanced etc..Silicone hose is the biggest feature of resistance to temperature changes of -60 degrees to 250 degrees, but the cost is very expensive, PVC is often used as ordinary water pipes, temperature sensitive, cheap and delicious, suitable for general working environment, no requirement for hoses. Compression resistant silicone hose can also withstand pressure, PVC in general, depends on the wall thickness and caliber. These are the differences between the silicone tube and the PVC tube.

Q: In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?: Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black. Long term use of plastics can cause fading and deformation. The chemical properties of silica gel are stable and the physiological inertia is good. They are very resistant to biological aging, have no rejection reaction with limbs, and have better anticoagulant properties.

Q: How to identify the quality of rubber pipes for sewage treatment?: A tubular rubber product used to transport gases, liquids, slurries, or granular material. It is composed of inner and outer rubber layer and skeleton layer. The material of skeleton layer can be made of cotton fiber, various synthetic fiber, carbon fiber or asbestos, steel wire and so on.

Q: How do I get the hose for the gas cooker?: In accordance with the relevant provisions of the country, the service life of plastic hose for two years, if used for a long time without replacement, easy gas leakage.

Q: What's the smell of petrol in the car and the trunk?! Especially after a long drive!: Some owners of the gas fuel to add too full, while refueling no leakage, but gasoline but follow the line and into the carbon canister in the tank, the steam release even a gasoline release out, if it is in air conditioning circulating state, the car will be able to smell the smell of gasoline.Solution: as long as the carbon canister inside the gasoline consumed, the excess carbon canister gasoline vapor through the engine negative pressure into the cylinder combustion, there will be no gasoline vapor overflow, and then open the window ventilation is.If you smell the smell of gasoline at the same time there is a pungent rubber flavor, it should be careful, there may be a harbinger of fire, you have to do a good job of checking and preventive measures in advance.
