Metal bellows is mainly composed of bellows part and two ends with the connection part (for one-time processing and molding). Its structure sketch is shown in Figure (I). Beijing Astronergy products are mainly:
Stainless steel anti-vibration joints, stainless steel expansion joints, stainless steel anti-vibration expansion joints, stainless steel transverse expansion joints, stainless steel string expansion joints, stainless steel outer cylinder protection expansion joints, metal hose, FM certified clean room special fire sprinkler hose, FM certified commercial building fire sprinkler hose, vacuum hose, teflon hose, rubber fittings, spring shock absorbers, suspension shock absorbers, air cushion shock absorbers, etc..
Our main production products are introduced as follows:
1, anti-vibration joints; these products are mainly used in the import and export of pumps to absorb the vibration of the pump and noise of the joints, we call anti-vibration joints, also known as the domestic metal hoses or pumps coupling, soft joints, etc., this type of vibration isolation joints we design considerations is to be the coefficient of elasticity of the small, the image of a softer, the more soft the better. The softer the effect, the better, of course, the design also needs to take into account the pressure can not be destabilized. Specifically, our products are divided into tie rod type anti-vibration joints and mesh cover type anti-vibration joints, tie rod type is divided into welded and integrated type.
This one-piece type can ensure the cleanliness of the pipeline, and the flange is made of carbon steel, which can be used in clean pipelines to reduce costs.
2, expansion joints; expansion joints are divided into axial expansion joints and transverse expansion joints, axial expansion joints are mainly used to absorb the horizontal direction of the pipeline expansion and compression. Transverse expansion joints are also called universal expansion joints, he absorbs the displacement in the right-angle direction through the offset of the bellows at both ends, which is mainly used at expansion joints and settlement joints.
3, special steel wire anti-vibration hose for thermal media oil, using a special process to manufacture anti-vibration hose, high temperature and high pressure resistance, the use of more secure than the general metal hose, the special circumstances of the netting pulled off, still will not leak, can be fought for the replacement of the time, while the use of Omega waveforms manufactured by the hose with the lowest coefficient of elasticity, the best vibration-damping effect. Thermal fluid special shockproof hose, manufacturing process as many as 14 ring welded seams.
4, through the U.S. FM certification of fire sprinkler hose, is divided into commercial building-specific and clean room-specific; which adjustable installation of commercial buildings, applicable to a variety of ceiling skeleton. The clean room hose has its own connecting fins and can be fixed on the T-type keel with T-type screws.
This fire sprinkler hose can be installed up to 20 times faster than traditional rigid hose, which effectively reduces installation costs and is widely used in major ceiling systems. Our hose automatic production line can produce up to 100,000 pieces per month.
5.Vacuum hose. Characterized as very soft, it is widely used in fields such as biopharmaceuticals and electronic engineering.
