Q:How to detect the reliability of rubber hose

Hose size measurement: the inner and outer diameter, outer diameter, wall thickness, enhancement layer concentricity, inner and outer layer of glue thickness, assembly diameter, new GB and ISO increased the length and the measuring point mark, provides no pipe joint and a hose length of various pipe joint measurement method.

Q:What's the smell of petrol in the car and the trunk?! Especially after a long drive!

Some owners of the gas fuel to add too full, while refueling no leakage, but gasoline but follow the line and into the carbon canister in the tank, the steam release even a gasoline release out, if it is in air conditioning circulating state, the car will be able to smell the smell of gasoline.Solution: as long as the carbon canister inside the gasoline consumed, the excess carbon canister gasoline vapor through the engine negative pressure into the cylinder combustion, there will be no gasoline vapor overflow, and then open the window ventilation is.If you smell the smell of gasoline at the same time there is a pungent rubber flavor, it should be careful, there may be a harbinger of fire, you have to do a good job of checking and preventive measures in advance.

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:How long is the service life of a rubber tube?

This is really bad to determine, the environmental impact is very large, so it is difficult to judge

Q:Toilet hose and water tank joints leaking, how to repair?

No rib sleeve, the use of pipe outside the buckle fixed, sealed, may be the aging of the tube, buckle clamping difficulties and other reasons. If the pipe is aging, you can cut or replace the tube in the aging part. It is difficult to buckle and clamp, so you need to change the buckle.

Q:Difference and application of rubber joint and rubber expansion joint

The utility model can be used to reduce the vibration and noise of pipelines, and can compensate for thermal expansion and cold contraction caused by temperature changes. Rubber expansion joints are used in chemical, construction, water supply and drainage systems!

Q:How to determine the tensile strength of GB rubber joint?

The cutting of sample can be done by punching machine. When punching sample, the following points should be paid attention to.The cutting force is uniform, not too large, and with mild soap and water and clean tap water wet specimens (or tools), if a sample cut down, it should be abandoned, not to repeat the old mark for cutting.The direction of specimen cutting should be consistent with the direction of tension and the direction of rolling.

Q:Can the copper tube of GREE air conditioner be changed into rubber tube?

Can not.One is the pressure rubber tube is not high, not more than 10 kilograms, the pressure in the air conditioning system requires more than 20 kilograms; at the same time, the air-conditioning system in operation, the temperature exceeds 100 degrees; no air conditioning system must be sealed, rubber tube under compression are not to do. In addition the rubber pipe corrosion, aging in exposed to the weather.

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:How can I keep the rubber tube for stethoscope?

I don't think this question should be considered purely from the point of view of sound transmission.
