Q:The selection of valves and fittings has the following requirements

The selection of hose inner screw thread joint can be rotated, because not hose and the joint body can rotate freely after buckling, configuration of internal thread after disassembly for hose.

Q:What is the difference between the precast beam of the bridge and the method of pulling out the rubber tube after pouring the concrete? What's the difference between design and calculation?

Corrugated pipe is included in the design of the amount of engineering, the role is: reserved strand space. Its length is calculated when the work length of the steel strand.

Q:Do you need a hose connection to connect the ventilation pipe to the exhaust fan? Under what circumstances? Under what circumstances?

The exhaust fan running noise and vibration is relatively large, the wind pipe made of sheet iron, the thin wall affected by the fan vibration will produce two times the noise, so the general air pipe to both sides of fan and soft joints, if no one in the floor or the condition of small diameter pipeline can not be added.

Q:What are the properties of stainless steel metal hose materials?

Stainless steel metal hose material is generally 304 stainless steel, the material of good ductility, flexibility, corrosion resistance, high temperature resistance.

Q:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?

Siphon principle: that is the principle of connected devices, plus in a closed container, the pressure on the liquid, everywhere equal. The siphon is filled with water, there is no gas, the water level of the water inlet is high, and the water outlet is closed with palm or other objects. The pressure is equal everywhere. When all are arranged, the water outlet is opened, although the atmospheric pressure on both sides is equal, the water level at the water inlet end is high and the pressure is large, and the water inflow is continuously flowed out of the water outlet.

Q:What's the difference between hose and hose for compressed air?

Generally, they are bundled into difficult to buy, no need to stand upright, probably because I have not seen large caliber. I also think this thing has absolutely nothing to stand up to. You say the hard one is probably covered with rubber and steel ring inside. Generally used to connect peripherals and larger gas equipment. The hoses we call are generally not very rigid. It breaks easily because it is too hard. Use often put hose made of spring shape, prevent the discount of breath

Q:Single ball chloroprene rubber flexible joint, Shanghai Song Jiang rubber ball joint manufacturer where?

Rubber joint is also called soft rubber pipe joint, flexible rubber joint, soft rubber joints, rubber joints, high-pressure rubber joints, rubber shock absorber, compensator.

Q:Is hot melt hose toxic and harmful?

Hot melt pipe using imported Teflon liner, has good flexibility, anti adhesion and resistance to high temperature (up to 250 degrees), can greatly reduce the carbonization phenomenon;

Q:How do you remove the burrs on the rubber joint quickly?

The thickness of the rubber joint burr than the thickness of the product is much thinner, so brittle speed than the speed burr brittle products quickly, in burr brittle and brittle products without this period of time can be hit by projectile projectile with frozen products deburring machine, thereby removing burrs in embrittlement.

Q:Standard for implementation of type KXT-1 rubber joints

It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into 5 kinds: single sphere, double sphere, different diameter body, bent sphere and wind pressure coil. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint.
