rubber expansion bellows 


2.Material:rubber ring,steel


4.12 years OEM producing experience


rubber expansion bellows,rubber duct joint,expansion bellow



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




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:Is the joint of ground heating pipe and aluminium plastic pipe general?
Pb can only serve as the system supervisor, the pipe joint is hot melt joint, and the aluminum plastic pipe can only be the system supervisor. That is, the joint of PEX and aluminum pipe is universal. If your site pipe is PEX, the tube is generic and cannot be generic if it is PERT.
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:What's the meaning of the plumbing PVC pipe joint specification "1/2" "X12" and "1/2" "x18"?
First specification 1/2 "X12": 1/2 inches in diameter and 12 inches in length.Second specifications 1/2 "x18": 1/2 inches in diameter and 18 inches in length.
Q:20ppr pipe joint is not what brand, 20ppr pipes can weld?
Standard requirement is to carry on the water and electricity warm transformation, is the water pipe and the joint choice same brand product.
Q:Will you be campaigning?
How about a return on all the money we've sent them that could have spent at home. How about the truth on how long they knew OBL was in the country and how didn't they just turn him over.
Q:describe how endodontics complies with health and safety?10 POINTS!?
The only way to know for certain what happen [sic] if you go outside in the lightning is to go outside in the lightning. If you're not killed when you go outside in the lightning please report back about your experience.
Q:What are the types of tubing and pipe couplings applicable to each occasion?
According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; pipe joints each form, according to the channel number and direction of joint points straight, rectangular, three other types; threaded connection and flange connection with the connection of the body. In addition, there are some special purpose pipe couplings.
Q:manual transmission: slowing and speed bumps?
~98% They have great dental plans. Teemu fake teeth look very good btw. I'd like to add that I'm grateful you didn't ask a stupid asinine puck bunny question. I would've had to get out my can o' whoop puck bun rse.
Q:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
UNF often used to transport water (high temperature), the imperial teeth often used to transport oil (high pressure).
Q:Standard Specification for jacket type pipe couplings for card sleeve couplings
Specification sheet, thick tube, B (water gas pipe), thin steel tube, A (wire pipe), metric, English, nominal, nominal diameter * wall thickness mm nominal
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.
