Characteristic of expansion joint

 

1. the compensation can compensate the thermal expansion: multi direction, metal compensator is much better than that of only single compensation.
2 . compensation installation error: because the system error is unavoidable in the process of pipe connection, the fiber compensator can compensate the installation error better.
3 .noise elimination: fiber fabric, insulation cotton itself has sound absorption, vibration transmission function, can effectively reduce the noise and vibration of boiler, fan and other systems.
4. no reverse thrust: because the main material for the fabric, the weak transfer. Fiber compensators simplify design, avoid the use of large bearings, and save a lot of material and labor.
5. good resistance to high temperature, corrosion resistance: the choice of fluorine plastic, silicone material has better resistance to high temperature and corrosion resistance.
6. sealing performance is good: there is a more perfect production and assembly system, fiber compensator can guarantee no leakage.
7 .light body, simple structure, convenient installation and maintenance.

Product Description

Metal Pipe Expansion Joints Chemical Resistant For Absorbing Thermal Growth

Metal Pipe Expansion Joints
 
Product description
 
Metal pipe expansion joints can withstand the design temperatures, pressures, as well as, provide the capacity necessary to absorb thermal growth of the piping system.
 
The thermal movement required can be axial, lateral or angular. In some cases, the pressure thrust of a pipe expansion joint must be restrained by the use of tie rods, hinges or gimbal while allowing the bellows to move through its design deflections.
Expansion joints with stainless steel bellows
Sunny Steel offers a wide range of expansion joints, suitable for numerous specific applications.
The Sunny Steel expansion joints portfolio basically consists of three main series:

  • Standard series: expansion joints up to DN 150 (6")

  • Industrial series: expansion joints up to DN 1.000 (40")

  • Special series: expansion joints >DN 1.000

The heart of all expansion joints is the metal bellows. Thanks to modern design and manufacturing facilities, all BOA expansion joints offer the following advantages:
 

  • High flexibility

  • Short build length

  • Large movement capacity

  • Durability and excellent chemical resistance

 

Metallic Expansion Joints Installation Guide

 

Storage:

  1. Store expansion joints in a dry/cool location such as a warehouse.

  2. Store flange face down on a pallet or wooden platform.

  3. Do not store other heavy items on top of expansion joint (s).

  4. Ten-year shelf life can be expected with ideal conditions.

Handling:
Do not lift with ropes or bars through the bolt holes. If lifting through the bore, use padding or a saddle to distribute the weight. Do not let expansion joints sit vertically on the edges of the flanges for any period of time. Do not lift on the shipping restraints.
Service Conditions:
Make sure the expansion joint rating for temperature, pressure, movements, and selection of materials match the system requirements. Contact the manufacturer if the system requirements exceed those of the expansion joint selected.
Alignment:
Expansion joints are not designed to make up for piping misalignment errors. Check with the manufacturer if piping misalignment is present.
Anchoring:
The main function of expansion joints is to compensate for axial pipe thermal expansion. Metal expansion joints must have the protection of adequate anchoring against the internal and thrust pressures of the media to prevent damage. Anchoring must be installed as close to the down stream end of the expansion joint as possible, with the originating equipment serving as the opposite anchor. Anchors must prevent pipe movement in any direction. Hangers or pipe pedestals cannot be considered to be anchors as they offer no restriction against side or end motion.
When designing an anchor for a metal expansion joint, consult the internal thrust force table from the appropriate expansion joint catalogue. The weight of piping, valves, and media, as well as the resistance of the piping to deflection, must be included as part of the design weight and strength of an anchor.
Anchors are required whenever a piping system changes direction. Expansion joints should be located as close as possible to anchor points. For additional expansion joint protection, it is recommended that control rods be installed on the expansion joint to prevent excessive movements from occurring due to pressure thrust of the line.
Guides:
Expansion joints must be properly guided and anchored in accordance with EJMA standards.
Pipe Support:
Piping must be supported so expansion joints do not carry any pipe weight.
Mating Flanges:
Install the expansion joint flange against the mating pipe flanges and install bolts so that the bolt head is against the expansion joint flange. Bolts should be installed from the bellows side (so that the bolt heads are adjacent to the bellows) to insure that the bolts do not interfere with the bellows during periods of compression. Flange-to-flange dimensions of the expansion joint must match the required opening.
Make sure mating flanges are clean and are matched to the type supplied with the expansion joint. Gaskets of appropriate material, size and temperature ratings must be used in all flange-to-flange type installations.
Bolt Torque:
Tighten bolts in stages by alternating around the flange. Never tighten an expansion joint to the point that there is
metal-to-metal contact between the expansion joint flange and the mating flange.
Shipping Restraints:
The expansion and compression movements are preset at the factory. The shipping restraints protect the expansion joint in its neutral position prior to installation. Remove the shipping restraints after installation and before hydro-testing the system.
Additional Tips:
1. Insulation or thermal blankets over a metal expansion joint should be supplied by the expansion joint manufacturer to preclude the use of corrosive chloride bearing insulation materials. Insulation should be installed to permit easy access to the flange area, to check bolting.
2. Do not weld in the near vicinity of a non-shrouded expansion joint without protecting the expansion joint from damaging weld splatter.
3. If an expansion joint is to be installed underground, or will be submerged in water, contact the manufacturer for specific guidelines.
4. Consider ordering a spare expansion joint. The cost of downtime of a critical expansion joint far exceeds the cost of a spare unit placed and protected in reserve on-site.
5. Whenever possible, install the expansion joint next to an anchor as indicated below not exceeding maximum distance to the 1st guide with at least two concentric pipe guides on the opposite side of the joint. Added guides are required to prevent bowing or bending of the pipe.
6. When an expansion joint is placed elsewhere in the line, at least two concentric guides must be used on each side of the joint with added joints installed as recommended in pipe guide spacing diagram.
7. The inside of all piping must be clean before installing and testing the expansion joints. Expansion joints should not be subjected to hydrostatic pressure tests beyond their rated working pressure.
8. Secure all anchors and guides before testing. Remove shipping bars prior to testing.
9. Expansion joints must be removed from the lines while the system is being tested hydrostatically at pressure exceeding allowable working pressure.
10. Expansion Joints fabricated with flow liners must be installed with the flow arrow pointing in the same direction of the media flow.
11. Single externally pressurized expansion joints must be installed with the moving end adjacent to the moving end of the pipe responding to the thermal expansion induced during system heat-up.
12. Failure to install according to instructions will void warranty.
