Q: Could you tell me the maximum pressure that the hose can bear?: This hose with material, wall thickness, diameter is Dudu, but there are special hose pressure testing machine test the size of the market, you take a look at the next.

Q: Does the rubber tube affect the engine in the car's tank?: I don't know what you mean by that, but the car's tank itself needs to be sealed and no clutter is allowed

Q: The rubber is sheathed on a metal cylinder. How should they 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: Is flexible rubber joint and telescopic device a kind of thing?: The utility model discloses a pipe expansion device, which is a connecting piece which is compensated by the size change caused by thermal expansion and cold contraction in the pipe connection. There are two kinds of pipe expander, one is rubber pipe telescopic device, and the other is metal pipe telescopic device.

Q: Acid burette and how to distinguish the basic buret: The following is a rubber tube acid basic titration burette is below the piston

Q: Flexible rubber joints. What do they mean by flexing?: Stainless steel bellows are not a kind of rubber joint.Flexure generally means that it can be bent repeatedly.The rubber joint mainly plays the axial and angular compensation displacement, and withstands the mechanical vibration, protects the pipeline not to burst.Stainless steel bellows can also be flexible, but the performance of vibration proof is better than that of rubber joints. If the requirements of the engineering drawings are rubber joints, it is better to be careful. Don't change it indiscriminately. Otherwise, the service life will be affected

Q: How should we distinguish between the silicone hose and the rubber tube?: Silicone hose is relatively soft, flexible, and looks better than other rubber tube gloss, color is mostly red, blue, translucent and other colors. Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black.

Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate.

Q: What kind of material does hose screw protection cover have? What are their advantages and disadvantages?: The utility model relates to a pipe protecting sleeve, which is a new product replacing the traditional metal protecting spring used for the protection of traditional rubber hoses. Alias: hose sheath, rubber tube outside protection special nylon spiral sheath, etc..

Q: How do I get the hose for the gas cooker?: Clean the stove inlet, then hose joints and joints into the stove over the red, with a pipe clamp or hose clamp hoop.
