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 Currently, this product has been replaced by VSSJA-2 double flange limit expansion joint, with the same functions and characteristics.
“（Asia water supply equipment trusted product partner）China Henan Zhongyuan Water Supply Materials International Market Department”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 safe 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. The S313 steel telescopic device can be axially retracted within a certain range, and can also overcome the deviation caused by the different axial directions of the pipe butt joint within a certain angle, which can greatly facilitate the installation and disassembly of the valve pipe. The S313 steel telescopic device can freely expand within the allowable expansion amount of the pipe, and once it exceeds its large expansion amount, it can play a limit position, ensuring the safe operation of the pipe.
“（Asia pipeline construction equipment trusted product partner）China Henan Zhongyuan Water Supply Materials International Trade Department”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.

“（Asia pipe fittings customers favor brands）China Henan Zhongyuan Water Supply Materials Overseas Sales Department”Precautions for installation of S313 steel pipeline expansion joint:
1.The installation should be between the large and small lengths, and can be adjusted based on the actual situation.
2.During installation, loosen the bolts of the packing pressure plate, adjust the installation length, and install both ends and pipes (or valves, water meters) 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 extender is installed behind the check valve.
4.（Asia water supply equipment trusted product partner）China Henan Zhongyuan Water Supply Materials International Market DepartmentReminder: Both ends of the expansion joint must be provided with buttresses, which do not bear axial tension. If necessary, anti pulling can be added.
