Q:How about rubber transfusion hose?
In accordance with the mixer developed within the layer, the middle layer and the outer winding hose layer; while using extrusion equipment will soft core inner tubing extrusion and coated release agent in coating or hard core, but should pay attention to the use of liquid nitrogen freezing method can not die.
Q:Standard for implementation of type KXT-1 rubber joints
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. Rubber joint manufacturing standard CB-T 965-95 CJT208-2005 to take over the compensation rubber flexible rubber joint CJT 3013.1-1993 KST flexible rubber joint
Q:What are the properties of an oil resistant rubber hose?
Oil resistant rubber tube, acid resistant alkali rubber hose product is a particular extension of high quality products. In fact, the ordinary general products hose used natural rubber, styrene butadiene rubber or butadiene rubber. That special oil resistance, acid and alkali are unique, oil resistant hose used chloroprene rubber, rubber; and acid, high temperature resistant hose, using ethylene propylene rubber, fluorine rubber or silicone rubber, etc..
Q:What kind of material is medical rubber tube?
General medical grade silicone tube, environmental protection, no odor, in line with food grade certification FDA/SGS/ROHS/LFGB, widely used in the medical industry. Friends do not understand, you can contact me. New silicon rubber pipe
Q:What are the main differences between stainless steel flexible joint and rubber soft joint?
High water use of this product, the pipeline must be fixed or fixed support bracket, otherwise the product should install anti pull off device. The force of fixed support or bracket must be greater than the axial force, or should install anti pull off device. And because the metal hose pressure resistance better, do not need to install.
Q:The rubber is sheathed on the metal cylinder. How can it be connected?
If you describe it, it is recommended that a soft binder such as 704 silicone gel will be used to prevent shock absorption and separation. Metal surface to rust treatment, clean can be coated adhesive, rubber cover surface is best polished, degreasing treatment effect is good!
Q:My company does high-quality rubber tube, all of the core method, and why use EPDM to do the inner tube, it is difficult to take off the core, please point out! What's the reason?
Hose core need special tooling, EPDM mandrel and rubber vulcanized rubber tube together will produce covulcanization phenomenon, easy to produce adhesion, so need special disposal to complete stripping, and should adopt non core industrial processing, I is a professional manufacturer of automobile rubber tube there is not clear I can ask each other AC.
Q:How do the automobile rubber hoses combine with the quick couplings?
The blue fast joint with fluorine is corresponding to the pressure, and the red fast joint with fluorine is corresponding to the high voltage
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:Why should the water stop strip be joined by heat instead of superposition?
Thermal connection is the safest and most reliable method of joint treatment, but it has certain requirements for technology.
