Introduction to S313 Steel Pipe Extender
S313 steel pipe expansion joint is a hardware fitting joint used to compensate for pipe expansion. Currently, this product has been replaced by VSSJA-2 double flange limit expansion joint, with the same functions and characteristics.
The characteristic of S313 pipeline expansion device is that the pipe body has three flanges. The main function of this product is to compensate for the expansion and contraction caused by thermal expansion and contraction, ensuring the operation of the pipeline. It has the following functions: compensating for the axial, lateral, and angular thermal deformation of the absorption pipeline; Absorb equipment vibration and reduce the impact of equipment vibration on pipelines; Absorb the deformation of pipelines caused by earthquakes and ground subsidence. {Full Name of the Enterprise} - The S313 steel telescopic device produced by the supplier's innovative pipeline can be axially retracted within a certain range, and can also overcome the offset caused by the different axial directions of the pipeline butt joint within a certain angle, greatly facilitating the installation and disassembly of the valve pipeline. The S313 steel telescopic device can be freely retracted within the allowable expansion amount of the pipeline, and once it exceeds its large expansion amount, it acts as a limit to ensure the smooth operation of the pipeline.
The S313 steel expansion joint provides great convenience for the installation and replacement of various water supply and drainage pipelines, water towers, pumps, water meters, and valves, and plays a good regulating role in the expansion and contraction of long-distance pipelines due to temperature differences.
Precautions for installation of S313 steel pipeline expansion joint
1. The installation of S313 steel expansion joint should be between the large and small lengths, and can be adjusted based on actual conditions.
2. During the installation of S313 steel expansion joint, loosen the bolts of the packing pressure plate, adjust the installation length, and install both ends of the joint and the pipe (or valve, water meter) according to the design requirements. Check whether the packing is properly placed, and then press on the packing pressure plate. Tighten the bolts diagonally to prevent deviation, so as to prevent leakage.
3. The retractor is installed behind the check valve.
4. Both ends of the S313 steel expansion joint need to be provided with buttresses, which do not bear axial tensile force and can be provided with anti pull off measures if necessary.
Advantages of S313 Steel Pipe Extender
1. The S313 steel expansion joint is very convenient to use. Whether it is a newly installed pipe or repairing an existing pipe, there is no need for on-site welding or gouging. It only needs to be connected according to the installation method, saving manpower.
2. The S313 steel expansion joint is equipped with a flange rubber gasket and a socket rubber seal ring, which can achieve rapid connection at the construction site.
3. A rubber flexible seal is used between the S313 steel expansion joint and the pipe, and the sealing strength can be adjusted to make the sealing more reliable.
