Q:Water heater hose 4 points and 6 points difference

4, in charge of and 6 in charge, from the caliber is obvious to see out, 6 in charge of greater than 4 in charge. Inside diameter 4 inches, have 13.2 millimeter about, 6 inches are 19.8 millimeter, 6 inches of pipe than 4 inches big. 6 points in diameter 1.6cm, 4 points in diameter 1.2cm, see thickness can be distinguished, 4 branch pipe diameter is 20mm, and 6 points water pipe diameter is 25mm, general heating with 6 points, slightly thick. The tap water is 4 inches fine.

Q:What are the materials used in rubber joints? What are their advantages?

Material has ordinary natural rubber, three yuan ethylene propylene (EPDM), nitrile and so onTo choose a different material, it depends on what kind of medium to go

Q:Can black soft rubber pipes be used as water pipes? Why is there a pungent odor?

Black rubber hose is not suitable for water pipes, black rubber tube, or all the use of recycled rubber is very high; and black rubber tube is generally industrial use.

Q:Can the natural gas hose not exceed 1.5 meters or 2 meters?

If the gas is longer, to Caution! Protective tube wall, as far as possible, to prevent accidental damage risk of gas pipe.

Q:Is flexible rubber joint and telescopic device a kind of thing?

Characteristics of rubber pipe telescopic device:First, small size, light weight, good elasticity, easy installation and maintenance.Two, the installation can produce axial, horizontal, angular and angular displacement, without the user pipe is not concentric, flange is not parallel restrictions.Three, vibration and noise reduction at work.Four, using a special synthetic rubber resistant to high temperature, acid and alkali resistance, oil resistance, chemical corrosion resistance is an ideal product pipeline.

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:The principle of the common bicycle valve

An elastic thin edge hose is placed below to form the whole of the core. In fact, it is a one-way valve. When inflating the bicycle tyre, the compressed air in the air pump enters the valve core from the hollow part, and the elastic rubber tube is top, and the air enters the tyre.

Q:What is the function of the rubber pipe joint and the installation pipe?

The inner seamless seamless rubber joint prevents the corrosive medium from eroding the inner wall of the rubber joint and improves the service life in the high temperature resistant, acid resistant and oil resistant pipes.

Q:Will the electric water heater be well connected with metal hose or hose?

For electric water heater, now the industry is required to use PPR pipe to its inlet and outlet for welding, on the one hand, long service life, can effectively prevent the water heater inlet and outlet leakage;

Q:The copper joint is leaking, and the tap water hose and copper joint are leaking

Because the water has temperature, and the thermal expansion coefficient of aluminum and copper is different,The coefficient of thermal expansion is different, that is to say, the interface is always moving (heat up, cold contraction),
