Negative Pressure Resistant ANSI/ASME Flanged Rubber Bellow“in vacuum pump”

Negative pressure-resistant ANSI/ASME Flanged Rubber Bellows “in vacuum pump”are independently developed by Shanghai Songjiang Group. They are mainly used in the import and export trade of centrifugal pumps, vacuum solenoid valve channels and their tailings pond pipelines.

Compared with the general ANSI/ASME Flanged Rubber Bellows, our company’s ANSI/ASME Flanged Rubber Bellows are equipped with increased pressure protection equipment to ensure that the ANSI/ASME Flanged Rubber Bellows are not easily flattened when subjected to negative pressure. The increased pressure ring is generally made of steel or stainless steel, which can handle 99.5% of the joints. Sucked condition. The negative pressure resistant joint is a shock absorber specially formulated for the negative pressure pipeline of the vacuum pump. Generally, the ANSI/ASME Flanged Rubber Bellow at the inlet of the centrifugal pump is very easy to be flattened. Therefore, we have released a negative pressure joint of the vacuum pump, which is suitable for reducing the vibration of the pipeline. , Reduce noise, good elasticity, easy to use.

Simple ANSI/ASME Flanged Rubber Bellows cannot withstand negative pressure. For example, the nominal diameter of the pipeline is 0.1kg negative pressure, the rubber hose will be flat, and the external working pressure of the pipeline will be completely different, so the nominal diameter of the negative pressure increases the negative pressure drainage tube. The negative pressure drainage tube is usually made of plastic. The nominal diameter of the shock-absorbing throat is increased by carbon steel pipe, and there is a negative pressure drainage tube. The plastic shock-absorbing throat cannot be flat, so the actual effect of the ANSI/ASME Flanged Rubber Bellow’s shock absorption and expansion will not be harmed. Negative pressure resistant ANSI/ASME Flanged Rubber Bellow ball is composed of inner rubber layer, improved layer with double-layer squeegee acrylic cord fabric, and outer rubber layer composite rubber hose. Depending on the material, the materials used are also different, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene rubber, silica gel, and fluorine rubber.

Negative pressure resistant ANSI/ASME Flanged Rubber Bellow

Each has the functions of high temperature resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, acid and alkali resistance, etc.

1. The raw materials are positive and negative plastics, with good sealing performance, light weight, and easy installation and maintenance. Long service life but prevent contact with sharp metal materials and equipment to prevent poking balls.

2. If the empty frame application can be equipped with a ductile support frame, use the top angle method to tighten the anchor bolts during installation.

3. If the working pressure of the pipeline is too high, use extreme anchor bolts to connect the flanges on both sides. Pressure-resistant ANSI/ASME Flanged Rubber Bellows are suitable for different pipelines, and have always been affirmed by users and praised by many five-stars. Model specifications can be customized according to customer requirements. The design scheme is unique, the structure is novel and effective, and the characteristics are reliable, which brings huge convenience and economic benefits to the construction and maintenance of the building.
