Q:What's the metal hose for fire fighting?

Fire hose is an important component of modern industrial equipment connecting pipelines. The metal hose is used as wire, cable, automatic instrument signal wire, cable protection tube and civil shower hose, specifications from 3mm to 150mm. Small caliber metal hose (inner diameter 3mm-25mm) is mainly used for precise optical ruler sensing line protection and industrial sensor line protection.

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 is the method of making large diameter rubber joint?

Rubber joint also known as shock absorber, shock absorber throat, the main function is to shock absorption, noise reduction, protection of the pipeline, compensation pipeline expansion, cold caused by displacement.Its structure: both ends are two carbon steel flanges, the middle is rubber shock absorption part.

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?

Construction process, in order to avoid concrete into bellows, influence later wear steel strand, construction units generally use PVC and other rubber tube into bellows, in order to double insurance, don't let concrete into. Its length is certainly larger than the length of bellows (750mm at one end for easy operation)

Q:How do I get the hose for the gas cooker?

Stainless steel bellows, stainless steel bellows, with a service life of ten years. The outside of the tube is covered with a layer of yellow plastic. All the inside are made of stainless steel. The ends of the pipe are connected with the mouth. There is also a black rubber piece, which is connected with the valve. After the tightening, the rubber sheet will expand and prevent the depression. Some live in a building or a cottage residents, plastic hose home is often a mouse or other insect bite, the use of stainless steel tube after it will not happen.

Q:Rubber soft joint, what brand of good, the best price is more reasonable. Don't say anything expensive.

There are many kinds of rubber joint products produced in the West Village of Gongyi. The prices are high and low,Gongyi Kin Kun water supply equipment factory produces rubber soft joints all year round

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

In the middle of the specimen, 4 parallel lines marked by the mark mark are used to mark two distances equal to the standard distance (type 1 is 25mm, type 2 is 20mm, and type 3 is lOmm), and each reticle shall be equidistant from the center of the sample. If the non-contact deformation measuring device is used, the proper marking device shall be used, and two parallel markings shall be placed on the narrow parallel part of the sample. Each mark shall be equidistant from the specimen center and perpendicular to the long axis of the specimen, and the specimen shall not deform during the marking.Style cutting, punching machine blanking note the above points, is to test the tensile strength of rubber joints based on, but also guarantee.

Q:Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?

According to GB1187, the rubber tube with an inner diameter of 127 has the maximum working pressure of 0.7MPa. The internal diameter tolerance is 2, and the outer diameter of the steel pipe is 127. If the purchase is appropriate, it should be sheathed, but the pipe factory is always taking negative tolerances.

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:How about rubber transfusion hose?

The last step is to protect the sulfide layer to remove the wound hose and then taking care, and pipe fittings withhold, then you can test the pressure sampling
