SSQ - 3 the performance characteristics of cast iron limit expansion
Bushing expansion is also called the slip joint, expansion joint, compensator. Expansion in a certain range can be axial expansion, can overcome the pipe is not within an Angle of axial offset, can greatly convenient valve pipe installation and disassembly, free expansion in the pipeline allows expansion amount, once over its largest scale, have the effect of limit, to ensure the safe operation of pipeline.
SSQ - 3 type cast iron limit expansion in detail
1. The bushing expansion the product for various water supply and drainage pipeline, water tower, water pump, water meter, valve installation conversion provides great convenience, for long distance pipeline due to temperature difference expansion has played a very good regulatory role.
2. The bushing expansion pipe within the product can be divided into cast iron (HT), galvanized (DX) and steel (SF) three. Work pressure points PN6, PN10, PN16 3 kinds.
3. The bushing expansion pipe before installation must loosen the pressure plate bolt, pull the product to install length, then tighten by diagonal method, do not partial pressure, such as aerial is used, the corresponding fixed bracket must be installed on both ends.
4. The flange connecting the GB4216.3-4126.5 standard.
5. If choose other specifications can be produced separately.
SSQ - 3 type cast iron limit expansion pipe connection
Flange connection, welding, buried type expansion pipe (not a gutter, set well when installation) generally adopt welding.
SSQ - 3 type cast iron limit expansion pipe installation considerations
1, bushing expansion pipe before installation should check its type, specification and pipeline configuration, must comply with the design requirements.
2, the expansion of in-band sleeve should be paid attention to the inner sleeve bobbin in the direction of the flow in the same direction with the media, hinged expansion of hinge rotation plane should be consistent with the rotational plane displacement.
3, the need for "tight" cold expansion, predeformation auxiliary components should be used in pipe installation is removed.
4, it is forbidden to use expansion deformation method to adjust the pipeline installation error, so as not to affect the normal function of the expansion, to 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 wave expansion is used as the installation of transport yellow auxiliary 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, bushing expansion all active components shall be stuck or limit the scope of its activity external components, should guarantee the active parts of normal movement.
8, when the water pressure test, coping with expansion pipe terminal time of the department of fixed frame for reinforcement, make line do not move or rotate. For the expansion 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.
