Unique design of constant force hanger

The structure of the constant force type supporting hangers of Bideli Energy Equipment (Jiangsu) Co., Ltd. is unique. It uses three sets of high-quality springs, and through a precisely calculated design of the transmission device, to maintain a constant force within the specified load and displacement interval, and always ensure that the direction of the force is vertical, which is the current international advanced structural form. Its performance far exceeds the products of other domestic factories. There are obvious scales on the panel of the support and hanger, which can directly read the cold and hot displacement and load values. Before leaving the factory, all the hangers are locked in the cold position with red clips. After installation and water pressure test, they are removed and placed on the side earrings.

Special stable spring

For the hanger, the spring is the most important component, which directly determines the long-term stability and safety performance of the hanger. Our company adopts special treatment technology (spring pre-relaxation treatment) and anti-corrosion treatment to make the performance of the spring far better than general products.

Inspection of Constant Force Support

According to the requirements of customer orders, set and test each constant force support and hanger, and issue a separate performance test report. To ensure that each manufactured product meets the required standards.
Function of spring support hanger
In order to prevent the external force from directly acting on the pipeline system, the normal thermal displacement of the pipeline and other pipe fittings must be prevented from being obstructed and limited. Therefore, the pipeline must be elastically suspended or supported according to a certain rule. Instead of constant force support hangers to play this role. The allowable load deviation is usually limited to 25% of the working load. When this range is exceeded, a constant force support hanger is used. The constant force support hanger can achieve constant force suspension and support over the entire travel range.

Mental Symmetrical design constant support hanger with support brackets Double load-tube guiding

Product description

Constant hangers and constant supports have a special design that allows for transforming the spring force into a constant force through a large vertical displacement range

Features

• Symmetrical design ensures direct flow of forces through axis of symmetry.
• Favourable power-weight ratios for reduced installation loads.
• Arranged by load groups and travel ranges to simplify selection (modular system).
• Consistent functional behaviour due to high-quality corrosion protection and maintenance-free, chemically nickel-plated finishes.
• Readily adaptable to the installation situation due to suitable designs and standardised accessories.
• Double load-tube guiding of constant supports for transmission of side loads.
• Secure connection of load chains due to load- and connection-compatible modular components.

Mode of operation

The mode of operation is based on the arrangement of three springs according to the parallelogram of forces. The design is distinguished by a high degree of functional precision along with wide load adjustment ranges.

Application

Constant hangers are used for piping and related components where higher levels of vertical travel occur. Their job is to transfer the working load over the whole travel area while keeping it constant, i.e. without any considerable deviations. The functional precision of the constant hangers is decisive for favourable long term behaviour of the components involved.

Portable Pipe Constant spring Hangers for various pipe installation

Product description

Constant force constant crane is designed according to the principle of torque equalization.Under the allowable load displacement, load torque and spring torque always adhere to the balance.For the pipe and equipment supported by the constant crane, it can provide a constant supporting force when the displacement occurs, so it will not bring additional stress to the pipe equipment.

The constant crane is generally used in the center where the displacement stress is reduced, such as the suspension part of the boiler body of the power station, steam, water, smoke, wind pipe and extinguisher of the power plant, and the center where such supports are required in the petroleum and chemical industries.When the thermal displacement of a lifting point in the pipeline system is greater than 12mm, it is appropriate to choose a constant crane to support, in order to prevent the pipeline system from generating risky bending stress and adverse stress transfer.

Features

Rated load: 0.2 ~ 400kN displacement: 0 ~ 508mm

Allowable field load conditioning quantity :±10%

Technical parameters

Regular load dispersion (including friction) within full travel :≤6% uniform load and design load dispersion within full travel :≤2%

When locked, 2 times maximum working load is acceptable.

Structure composition and working principle

Our company mainly operates and consumes the spring type constant force support and hanger, and can also provide the main and auxiliary spring type or other ways of constant force support and hanger according to the user's request.The spring constant force support hanger is designed according to the principle of torque equalization.It relies on the exquisite geometric design, so that load torque and spring torque in the work process has been balanced, in order to adhere to the constant support force, can eliminate or reduce the additional stress on the pipeline or equipment.

Main and auxiliary spring type constant force support hanger is designed according to the principle that the resultant force is constant under the action of the main spring force and the auxiliary spring force.

The spring type constant force support hanger is mainly composed of cylindrical spiral spring and lever mechanism.Because its spring and component manufacturing technology is simple, mature, the product performance is stable, the economy is good, has been used for a long time in the domestic, therefore is the most widely used type;The performance of the constant force hanger with the butterfly spring is relatively difficult to control, while the main and auxiliary spring constant force hanger requires high precision of the spring, so it is relatively difficult to manufacture, so it has not been widely used.

The company USES the introduction of ITT Grinnell support hanger design, manufacturing technology, the introduction of the domestic production of 58 series of constant force support hanger, with a variety of ways, selection of bento, excellent performance characteristics, by domestic and foreign users.
