SSQ type sleeve type telescopeic device
The telescopic expander is also called a telescopic joint, an expansion joint, and a compensator. The telescopic expander can be axially extended and retracted within a certain range, and can also overcome the offset caused by the different axial joints of the pipe within a certain angle, which can greatly facilitate the installation and disassembly of the valve pipe, and allow the amount of expansion and contraction in the pipe. It can be freely stretched and stretched. Once it has passed its large expansion and contraction, it will play a limit role and ensure the safeoperation of the pipeline.
1. Casing type retractor This product provides great convenience for the installation and replacement of various water supply and drainage pipes, water towers, water pumps, water meters and valves. It provides a good adjustment function for long-distance pipelines due to temperature difference expansion and contraction.
2. Casing type retractor The inner tube of this product is divided into cast iron (HT), galvanized (DX) and steel (SF). The working pressure is divided into three types: PN6, PN10 and PN16.
3. Before installing the telescopic retractor, loosen the platen bolts, pull the product to the installation length, and then tighten it diagonally. Do not bias it. For overhead use, install the corresponding fixing brackets at both ends
4. The flange connection adopts GB4216.3 - 4126.5 standard.
If other specifications are selected, they can be produced separately. Connection method: Flange connection and welding, direct-buried retractor (non-ground trench, when installing the well) is generally welded.
