Stainless steel corrugated compensator is introduced
Metal compensator, as a flexible pressure pipe fittings installed in the liquid delivery system, to compensate for pipe or machinery, equipment to connect the displacement of each other, to absorb vibration energy and can play a role reducing vibration, sound, etc, has good flexible, lightweight, corrosion resistance, fatigue resistance, high and low temperature resistant characteristics.
Metallic compensator for its USES different choice of different metal materials. Because its material is different, the compensator is processed by the performance and use is also different.
Stainless steel metal compensator with austenitic stainless steel materials, or materials, according to the requirements of customers with excellent flexibility, corrosion resistance, resistance to high temperature (235 ℃ ~ + 450 ℃), high pressure resistance (up to 32 mpa), can connect to any direction in the pipe, temperature compensation and vibration absorption, noise reduction, change medium, eliminate pipeline conveying direction or mechanical displacement between the pipe and equipment, such as double flange stainless steel metal compensator for displacement and vibration of pump, valve, etc. The flexible joint is particularly applicable.
Stainless steel metal corrugated compensator use two kinds, one kind is spiral corrugated, the other is a circular ripple.
Spiral stainless steel metal compensator is a corrugated spiraling configuration of tubular shell, between the adjacent two corrugated a helix Angle, all corrugated can be connected by a spiral line.
Circular stainless steel metal compensator is corrugated is a closed circle circular tubular shell, between wave and wave composed of circle ripples in series. Circular stainless steel metal compensator by seamless pipe or welded pipe forming processing. Subject to the limit of the processing method, compared with the spiral corrugated pipe, the length of single tube usually shorter. Circular stainless steel metal compensator has the advantage of good flexibility, small stiffness.
Performance testing include: stainless steel metal compensator is stiffness test, stability test, fatigue test, the fracture test, vibration test, impact test, high temperature fatigue test and so on. Of stainless steel metal compensator performance test standards are: EJMA, ASME B31.3, ROCT27036, OCT B5.5588, etc. The EJMA is given stability test, fatigue test, the fracture test method. High temperature fatigue test is given to the test pieces, stress range, insulation (maximum displacement) time requirements and the method of data processing.
Type test: (1) the stiffness of axial, lateral bending, bending stiffness measurement method and the boundary condition is proposed requirements, and the number of test and data processing method is given.
: (2) the fatigue test of axial type, straight type pressure balance, hinge, sensibility, flexible pole structure in the form of compensator to simulate the actual deformation conditions for fatigue test, the test methods and criteria are given.
(3) the vibration test: the vibration of the vibration test method, frequency range, vibration acceleration, the requirement of the sweep time of each band.
(4) impact test: the shock acceleration, pulse duration, the impact number of times and the boundary conditions of impact test.
With the above introduction, you can see that the standard due to the different applicable objects, with emphasis on the test methods and requirements. With EJMA give high temperature fatigue test method for creep temperature range in the work of stainless steel metal fatigue ? compensator
Installation and use of stainless steel bellows compensator
1, stainless steel corrugated compensator before installation should check its type, specification and pipeline configuration, must comply with the design requirements.
2, stainless steel metal compensator with inner sleeve should be paid attention to the inner sleeve in the same direction, the direction of the cheese and medium flow hinged metal compensator hinge rotation plane should be consistent with the rotational plane displacement.
3, need to be "cold" tight stainless steel metal compensator, predeformation auxiliary components should be used in pipe installation is removed.
4, it is forbidden to use the deformation of stainless steel corrugated compensator method to adjust the pipeline installation error, so as not to affect the normal function of the compensator, reduce the service life of the components and piping, equipment, supporting the load.
5, the installation process, do not allow the welding slag splash to the shell surface, do not allow the wave shell by other mechanical damage.
6, piping installation has been completed, should be removed as soon as possible on the stainless steel metal compensator is used as the auxiliary installation transportation yellow positioning components and fasteners, and switch to a specified position limit device according to design requirements, make the piping have ample compensation ability under the environmental conditions.
7, stainless steel corrugated compensator all active components shall be external components are stuck or limit the scope of its activity, should guarantee the active parts of normal movement.
8, when the water pressure test, equipped with stainless steel metal compensator pipe terminal time of the department of fixed frame for reinforcement, make line do not move or rotate. Stainless steel metal compensator for gas medium and its connecting line, and pay attention to the water filling whether need to add temporary support. Hydrostatic test water cleaning fluid 96 chloride ion content is not more than 25 PPM.
9, after the water pressure test, as soon as possible the water wave shell, shell surface dry and quickly will wave.
10, contact with the stainless steel metal compensator of insulation materials should not contain chlorine.
