Connection method of stainless steel water supply pipe

1. Compression type: Insert the piping into the pipe fittings. Both ends of the pipe fittings are protruding U-shaped grooves with built-in sealing rings. Use special pipe fitting tools to press the socket parts for connection.

Scope of application: DN (nominal diameter) 100mm, can be installed and applied in the dark.

2. Compression type: Insert the piping into the nozzle of the pipe fitting, fastens it with a nut, and compress the sleeve of the nozzle through the sealing ring with a spiral force to play a selling role and complete the piping connection. Scope of application: DN150mm, can be mounted in the dark.

3. Welding type (socket or butt welding): ring-shaped argon arc welding is made on the usual socket-type pipe fittings and matching, which has a sealing effect and completes the matching connection. Scope of application: For public buildings and large buildings, the DN is 15mm-100mm, and the DN is greater than 100mm, usually with conventional butt welding; indoors can be mounted in the dark or buried outdoors.

4. Quick-connect flange type: ring-shaped argon arc welding is performed on the flange and the matching, and the sealing gasket between the flanges is compressed with a quick clamp to play a selling role and complete the matching connection. The applicable range DN is 15 mm-100 mm, and the pipes of public buildings and large buildings.

5. Taper thread type: the external thread sleeve is welded with the matching ring argon arc, and the internal thread pipe fittings are connected with a tapered pattern to play a selling role to complete the matching connection. The applicable range is DN 65 mm-100 mm. The pipelines of communal buildings and large buildings can be used in harsh environments such as foundation sinking, high temperature, and high pressure.

6. Limit compression type: the piping adopts a flanging or port wedding ring, and the connection method is live or semi-live connection. After the rubber sealing ring is compressed by 20%-30%, it enters the metal seal groove and adopts the limit Seal to protect the sealing element. The joint can be done in copper or carbon steel. The scope of application is DN below 400mm, and it is suitable for harsh environments such as foundation sinking and various high temperature and high pressure.

7. Articulated quick-connect flanges: make traditional flanges into articulated flanges, piping port flanging or wedding ring, ring groove embedded in the groove, sealing rubber parts in the groove, using the method of limiting compression to protect the Sealing element. The applicable range DN is below 400mm, and it can be used as a buried pipe.

8. Heat-shrinkable pipe fittings: On-site welding can be employed to pipe connection. Since the welding point cannot be handled on the construction site, heat-shrinkable pipe fittings are employed to supplementary sealing. A rubber welding sleeve is placed on the pipe welding point, and then a layer of a special cross-linked polyethylene sleeve is applied to shrink under the action of heat to achieve the Shrink seal. The applicable scope is pipelines whose DN is below 400mm.
