Q: How to determine the parker381 hose joint?: More knowledge extension: PARKER hose assembly pioneered the use of rubber stripping (No-Skive) do not withhold technology, to avoid the damage caused by removing the plastic hose, the maximum prolong its service life. PARKER KBG hose connector realize the skiving integration design, profile design of sleeve internal special pre withhold is the key to reliable connection. No stripping rubber hose, rubber stripping not withhold joints, without withholding equipment adjustment, a perfect combination of PARKER hose assembly.

Q: What is the essential difference between rubber expansion joint and rubber joint?: Rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The product uses rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance etc., using polyester cord fabric skew high strength, strong stability and the hot and cold composite, after high pressure, mold temperature and curing. As the rubber joint has good comprehensive performance, it mainly acts as shock absorption, noise elimination and noise reduction. Therefore, it is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects.

Q: Water heater hose 4 points and 6 points difference: 4, in charge of and 6 in charge, from the caliber is obvious to see out, 6 in charge of greater than 4 in charge. Inside diameter 4 inches, have 13.2 millimeter about, 6 inches are 19.8 millimeter, 6 inches of pipe than 4 inches big. 6 points in diameter 1.6cm, 4 points in diameter 1.2cm, see thickness can be distinguished, 4 branch pipe diameter is 20mm, and 6 points water pipe diameter is 25mm, general heating with 6 points, slightly thick. The tap water is 4 inches fine.

Q: How can we prevent the aging of rubber tubes?: The second is the design of the structure of the rubber products (especially damping products), has a great relationship between aging and fatigue, should avoid stress concentration! If the product is good has been produced to prevent aging, more trouble! Can be sprayed on the rubber surface, spraying insulation polymer.

Q: What are the types of cable metal hose connections?: The utility model is mainly used for connecting the metal hose and the steel pipe, and the installation of the clamping sleeve is not required to be sheathed on the steel pipe

Q: Why should liquefied petroleum gas use strong rubber hose and liner?: These gases on the rubber has a certain corrosion, swelling (not resistant to oil will speed up swelling), aging effect, liquefied petroleum, so choose rubber seal to consider oil resistance, corrosion resistance, swelling. Petroleum gas is corrosive to ordinary rubber pipes and gaskets and easy to cause air leakage. Therefore, it is necessary to use rubber pipes and gaskets with strong oil resistance.

Q: What are the categories of hose?: According to the use of performance: ordinary hose (cloth water hose, air hose, braided hose, air hose braided fiber, fiber winding hose, fiber winding air hose (hose); medium resistance oil resistance, acid and alkali resistant hose, steam hose etc.); special hose (hydraulic hose, brake hose drilling mud, hose, spray hose, hose extrusion etc.) Hengshui Yajie rubber.

Q: Three yuan ethylene propylene rubber tube covered with nylon PA66, what glue can not afford the layer?: Because the nylon 66 excellent heat resistance, chemical resistance, strength and convenient processing, so it has been widely used in the automotive industry, currently has almost all parts for automobile, such as engine parts, electrical parts and body parts.

Q: How can the soft joint of the pipe be elongated during use?: Because the pipeline joint is a kind of soft rubber products, in the use of high temperature and high pressure rubber is easy to deform or due to internal pressure is easy to crack and surface as the main parts of long distance pipeline, influenced by the use of the process will produce corrosion phenomenon,

Q: What kind of material does hose screw protection cover have? What are their advantages and disadvantages?: Hose cover is usually made of nylon or polyethylene
