Q: Between the two flanges in the middle of the rubber pipe, what is the name of the connection?: The product is mainly composed of inner and outer rubber layer, cord fabric and steel wire ring. It is formed by vulcanizing with metal flange at high temperature and high pressure

Q: The newly purchased natural rubber tube is too large. How can it be removed?: The activated carbon is divided into 8 parts, put in the dish, the dumbbell rubber smell removed - prepare 400 grams of ash, used to be among them after washbasin packing box of formaldehyde, because some of the harmful substances is colorless and tasteless, more clean, more secure. In the bubble tea, put in the refrigerator can achieve the deodorization effect. If you do not have tea, you can also cut lemon or willow, and only half a small piece will be effective. Smoke in room. The soaked waste tea leaves dried, placed in the corner of the room, using the principle of physical adsorption of tea to remove dumbbells, rubber flavor. You can also use a towel dipped in diluted vinegar, go to the dumbbell rubber flavor.

Q: How to prevent leakage of rubber joint check valve?: As the valve body is particularly flexible, to ensure maximum resistance to back pressure at the same time to minimize water head, and some only one centimeter water head can be opened, so that the valve emissions and back resistance to achieve a perfect unity.

Q: How long is the service life of the gas hose?: The protection work is very important, regular replacement of gas hose and make use of the gas hose gas pipeline safety in general, the gas hose has a life span of two years, usually pay more attention to inspection / check whether the aging hose, wear, corrosion or bad connection, avoid leakage.

Q: Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?: According to GB1187, the rubber tube with an inner diameter of 127 has the maximum working pressure of 0.7MPa. The internal diameter tolerance is 2, and the outer diameter of the steel pipe is 127. If the purchase is appropriate, it should be sheathed, but the pipe factory is always taking negative tolerances.

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: The main features of Linatex rubber tube or what are the characteristics?: Linard, BB:, halogenated butyl rubber. Acid and alkali resistance, good air tightness, high temperature resistance.Linaplus, FG:, natural rubber, FDA certified, for long-term exposure to food applications.Linaplus, OZ:95% natural rubber, excellent abrasion resistance, UV resistance, and ozone performance

Q: In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?: Silicone hose is relatively soft, flexible, and looks better than other rubber tube gloss, color is mostly red, blue, translucent and other colors.

Q: What are the types of metal hose couplings?: DPJ external threaded end metal hose joint is an extension of JB/GQ 0552, /83, D95-5 metal joint;The metal joint is made of zinc alloy. The surface is zinc plated, frosted or chrome plated. The structure is close, without porosity and high strength. The metal hose is connected reliably and has beautiful appearance;The metal joint is an end connection and a linear connection for connecting the metal hose to the case;Suitable metal hose: JS, JSH, JSB, JSHG;It is recommended to use an inch metal hose joint or a metric thread metal joint;Can be customized a variety of non-standard metal hose joints, special metal joints.

Q: What with the appropriate suction tube Dichotomanthes tube and rubber machine: The spiral tube called spiral steel tube or spiral welded pipe, the low carbon steel or low alloy structural steel strips in a helical line certain angle (called forming angle) rolled into a tube, then the tube welding seam made up, it can be used in narrow strip production of large diameter steel pipe spiral pipe is mainly used in oil.
