Q:What is the method of making large diameter rubber joint?
There are three ways to apply large diameter flanges:First, raw material steel plate, through the template blanking: 1/4, 1/6, 1/6, and then welding lathe processing, drilling.Second, hot rolled flange blank, then lathe, drilling.Third, cold roll flange blank, steel plate into strips, cold roll machine, roll round, lathe, drilling machine processing.
Q:The rubber is sheathed on a metal cylinder. How should they be connected?
With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean
Q:How can the tightness of rubber tube and metal pipe joint be ensured?
To see what kind of material hose, small 1MM~2MM, if the inner pressure then add hoop.
Q:What's the difference between hose and hose for compressed air?
In use, it is usually marked with color. For example, the intake is made of blue, and the exhaust is made red, but it is not necessary.
Q:What are the materials used in rubber joints? What are their advantages?
While the three EPDM is ethylene propylene diene hydrocarbon, and non yoke of three yuan is the main characteristic of copolymer, excellent oxidation resistance, ozone resistance and anti erosion ability, also has excellent curing characteristics. Simple speaking is resistant to high temperature.The nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high abrasion resistant, good heat resistance, strong adhesion. (oil).
Q:Is the electric water heater well connected with the metal hose?
On the other hand, the utility model can effectively avoid the frequent switch of the water heater power switch because of the two grounding. Therefore, the metal pipe connection does not meet the safety and installation specifications.
Q:What is a rubber core pulling method?
For short component hole, a hose can be used to bend through two parallel holes; if it is used for retaining hole of long component, the two hoses of anchor can be connected by iron sheet sleeve. The length of the bushing should be 400 - 500mm, and the inside diameter should be 2 - 3mm larger than the outer diameter of the hose. The fixed position of steel derrick hose available, spaced not more than 0.5m, and fasten with steel skeleton.
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:What is the essential difference between natural rubber and three yuan ethylene propylene rubber?
Vulcanized natural rubber elastic rubber and its crosslinking density is not too high, the elasticity is high. For example, in the range of 0-100 DEG C, elasticres at 50-85 DEG C, the elastic modulus of steel is only 1/3000, the tensile elongation is up to 1000%, to 350%, after retraction of permanent deformation is only 15%, a higher elasticity of natural rubber in the general rubber after polybutadiene rubber.
Q:Access toilet water inlet hose joints, how to repair water?
However, be careful not to hold back too much to prevent the toilet from being cracked. Because before if overwind, or rust, is not open, can only remove the drainage valve inside with a pipe wrench stuck open.
