rubber expansion bellows,rubber duct joint,expansion bellow

 

1:details: 

Rectangular duct fabric expansion joint is also called non-metallic compensator, non-metallic expansion joint. Is a high performance non-metallic material, advanced structure, reliable performance, it has a universal power compensation and absorb thermal expansion characteristics, with a high resistance, low temperature, pressure, corrosion resistance, enable the role of the left at a fixed point in force is almost zero (in the design calculations can be ignored), installation of large degrees of freedom, axial radial allow greater deviation of up to 10% of pipe diameter, -20%, can muffler isolation, and may from time to by the pipe dimensions and shape of the restrictions, flexible fabric expansion joints can greatly optimize the quality, the ideal metal rigid expansion joint replacement products, various kinds of imported fabric compensator is a good alternative.

 

The product is now widely used in steel mills, aluminum plants, cement plants, power plants and other industrial enterprises in the hot and cold air pipes, fans import, export and industrial furnaces heat pipes, the use of plant products Huitong plumbing works well, has won user praise.

 

2:we can supply:

 

1.Flange - Steel to SABS 1431 Grade 300WA 

 

2.DN20mm - DN3000mm.

 

3.The bellows consists of two symmet

 

3:Advantages:

 

1) Expansion joint are low cost vibration and deflection absorption components in fluid conveyance pipelines.

 

2) The bellows consists of two symmetrical connecting ends, either threaded unions for smaller nominal bores or flanged ends for larger nominal bore pipelines.

 

3) The body of the bellows is essentially a robust rubber cylinder that is capable of absorbing vibration and movement in pipeline components.

 

4) Bellows are often installed in-line with water pumps as the absorber of the operating vibration of the pump and movements due to pump start up, shut down.

 

5) Bellows are also able to absorb axial displacement due to pipeline expansion and contraction, and lateral displacement and pipeline angularity.

Q:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
ZG is a commonly known as cone, cone thread processing, pipe joint is generally the old GB marked Rc for metric threads to represent the thread pitch, with every inch of the thread number, this is the biggest difference between them, metric thread is 60 degrees equilateral tooth type. 55 inch thread is isosceles tooth type of thread, 60 degrees. Metric units for metric threads; British and American systems. Pipe thread is mainly used for pipe connection, the internal and external threads are closely matched with straight pipe and cone pipe two kinds. Nominal diameter refers to the diameter of the pipe to be connected. Obviously, the diameter of the thread is larger than the nominal diameter. 1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches.
Q:Is the hydraulic pipe joint stainless steel or carbon steel?
Of course, the corrosion resistance can not be done. But wear resistance, machinability is much better than stainless steel. See what parts of your connection are made of
Q:What are the specifications and models of metal hose couplings?
It is mainly used for connecting the box and hose in place. Open the box in the box and plug into the joint. The external thread joint is fixed with the lock. 2, mainly used in screw thread connection cable pipe and hose.
Q:Maintenance skills of fire hose clamp joint leakage
Detailed explanation of maintenance technology for fire hose clamp joint leakage:Trench type fire pipeline after used for a long time, if all of a sudden pressure relief after prone to the displacement of the pipeline caused by clamp joint Water Leakage, by tightening the clamp bolts do not necessarily have a good effect, because of aging, lack of elastic rubber ring.
Q:What is a reinforced pipe joint?
It has a certain mechanical strength and good shock absorption. It is suitable for making parts under moderate stress, working parts in weak corrosive environment, such as cover, bearing seat, valve body, hand wheel and so onThe main purpose of strengthening the pipe joint is to connect, install and maintain conveniently.
Q:Can flared and jacketed hydraulic couplings be used as gas line couplings?
And it is not convenient to use, the general use of gas joints are fast plug.
Q:110 degree PVC pipe joint
PVC pipe (PVC-U pipe) rigid PVC pipe is made of PVC resin and stabilizer, lubricant and so on. It is extruded and formed by hot pressing method. It is the earliest plastic pipe to be developed and applied. PVC-U pipes are corrosion resistant, easy to adhere, low in price and hard in texture, but because of the exudation of PVC-U monomers and additives, they are only suitable for the feed water system with a temperature of not more than 45 DEG C. Plastic pipes are used to transport potable water, waste water, chemicals, heating and cooling fluids, foodstuffs, ultrapure liquids, slurries, gases, compressed air, and vacuum systems.
Q:Specification for thread of gas couplings
5, pneumatic joints of different series used in different places, specific size can find these brands of websites, generally all brands have their own web site, the website has relevant dimensions description.6, if not clear enough, you can find these brands in Baidu, and then call them to obtain product catalogs, so that more clear.
Q:How tight is the gas pipe joint?
For a fixed gas pipeline, it should be installed by a professional Gas Co, and the individual shall not change the sealing of the joint. It should be sealed by special sealant. Plastic pipes should not be too long, should be far away from the electrical circuit, and the high temperature area of the hearth.
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
A part of a hydraulic system between a high pressure tubing and a high pressure tubing.Classification: hydraulic hose, high pressure ball valves, quick couplings, odd intention ferrule type pipe joint, welded pipe joints, high-pressure hose, transition pipe joint, sleeve type pipe joint, three way pipe joint, non-standard pipe joint, flaredfitting, rectangular pipe joint, rotary tube connector, quick connector, stainless steel pipe fittings, copper fittings.
Our products are of advanced design, rational structure, stable performance, and flexible and high anti-fatigue properties. With our quality assurance system, we improve comprehensive test means and attain the ISO9001 quality system certification and pressure pipe component production license.
