[Concentric Reducer] Pipeline Expansion Joint Introduction：

Concentric Reducer Pipeline Expansion Joints are used in various medium pipelines in construction water supply and drainage projects, central air conditioning pump room units, chemical enterprises, ships, fire engineering, pharmaceuticals, and other industries. Concentric rubber joints with different diameters with product solutions to solve the problem of different diameters when connecting metal pipes, and at the same time have the effect of shock absorption and noise reduction.

“Rubber pipe fittings that need to be reduced in diameter and connected with different diameters” are commonly known as reduced diameter rubber joints

Reducer Pipeline Rubber Bellows, reducing rubber head, reducing rubber head are collectively referred to as Concentric Reducer Pipeline Expansion Joint. This product is mainly used in pipes with different diameters or requiring reduced diameter connections. The maximum pressure is 1.6MPa, It has good elasticity, large displacement, low resonance noise of pipeline units, easy installation, compensation for pipeline displacement, and a good makeup for the gap of large-scale different-diameter pipeline connections in the industry.

[Concentric Reducer] Pipeline Expansion Joint Structure

The inner layer of rubber, the middle layer of nylon cord reinforced, and the outer rubber layer composite rubber curved sphere is a product composed of cast iron and forged metal flanges vulcanized by injection molding. The product facilitates the connection of metal pipes with different diameters and is a novel flexible pipe joint.

Concentric Reducer Pipeline Expansion Joint, also known as reducing shock absorbers, pipeline shock absorbers, shock absorbers, soft joints, flexible joints, and high-pressure joints. This product is mainly used in pipes with different diameters or requiring reduced diameter connections. The maximum pressure is 1.6MPa, It has good elasticity, large displacement, low resonance noise of pipeline units, easy installation, compensation for pipeline displacement, and a good make up for the gap of large-scale different-diameter pipeline connections in the industry.

Concentric Reducer Pipeline Expansion Joints are used in various medium pipelines in construction water supply and drainage projects, central air conditioning pump room units, chemical enterprises, ships, fire engineering, pharmaceuticals, and other industries. Concentric rubber joints with different diameters can solve the problem of different diameters when connecting metal pipes, and at the same time have the effect of shock absorption and noise reduction.

Concentric Reducer Pipeline Expansion Joint Medium selection

Neoprene (CR) Corrosion Resistant
Nitrile rubber (NBR) oil resistant
EPDM/EPDM acid and alkali resistant
Fluorine rubber (FPM) high-temperature resistance

The main feature is that it can solve the problem of different diameters when connecting metal pipes, and at the same time, it has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It is composed of an inner rubber layer, nylon cord reinforced rubber sphere, and loose metal flange. It has the characteristics of high-pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petroleum chemicals, ships, pumps, compressors, fans, and other piping systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15℃～120℃. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30℃～250℃.

Concentric Reducer Pipeline Expansion Joint Instructions

When using Pipeline Expansion Joint for a high-rise water supply, the pipeline must have fixed supports or fixed brackets, otherwise, the product should be equipped with an anti-pull-off device. The force of the fixed support or bracket must be greater than the axial force, otherwise, the anti-pull-off device should also be installed.

Concentric Reducer Pipeline Expansion Joint Scope of use

Reducer Pipeline Expansion Joints are widely used in various medium pipelines in construction water supply and drainage projects, central air-conditioning pump room units, chemical enterprises, ships, fire engineering, pharmaceuticals, and other industries. Concentric Pipeline Expansion Joints with different diameters can solve the problem of different diameters when connecting metal pipes, and at the same time have the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high-pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation.

Concentric Reducer Pipeline Expansion Joint Installation

Avoid contact with sharp metal instruments to avoid puncturing the rubber ball of the tube. Use elastic brackets when installing, and tighten the bolts diagonally. If the pressure of the pipeline passing through the reducing rubber joint is too high, use limit bolts to connect the flanges at both ends together. The connection of the inlet of the pump unit should generally be installed on the top and parallel to prevent the gas in the pipeline from accumulating at the pump port. It is forbidden to install at the limit of displacement, keep away from heat sources, and is strictly forbidden to use non-compliant product media connectors for installation;

Concentric Reducer Pipeline Expansion Joint Maintenance

Concentric Reducer Pipeline Expansion Joints are mainly produced from natural and synthetic rubber. The Pipeline Expansion Joint of the products have a certain service life, and they will age after a long time. In terms of preservation, in addition to being placed in a cool and dry place that is not exposed to sunlight, it should also be kept away from things containing strong acids and alkalis. Regularly maintain the working environment of the fittings.
