Key Features of HDPE Electrofusion Blocking/Plugging Saddle for Fuel Gas
- Electrofusion welding: has built-in resistance wire for automatic welding with high joint strength and gas tightness.
- Blocking dedicated: forms a permanent seal directly on the saddle without cutting the main pipe.
- Material compatibility: provides homogeneous connection with PE80, PE100, and PE100RC pipes with no galvanic corrosion.
- Fuel gas resistant: meets rapid crack propagation and long-term hydrostatic strength requirements.
Manufacturing Process of HDPE Electrofusion Blocking/Plugging Saddle for Fuel Gas
Each is produced with precisely embedded resistance wire to enable automated electrofusion welding.
Critical Process Parameters of HDPE Electrofusion Blocking/Plugging Saddle for Fuel Gas
- Uniformity of resistance wire coil spacing and embedding depth.
- Cleanliness and oxide layer treatment of the welding interface.
- Calibration of electrofusion voltage and time to match pipe material.
Raw Material Characteristics of HDPE Electrofusion Blocking/Plugging Saddle for Fuel Gas
- PE80: MRS 8.0 MPa, suitable for medium and low pressure gas networks.
- PE100: MRS 10.0 MPa, preferred for high pressure gas service.
- PE100RC: combines PE100 strength with point load resistance.
Typical Applications of HDPE Electrofusion Blocking/Plugging Saddle for Fuel Gas
- The fitting provides permanent sealing of abandoned branch outlets on gas mains.
- safely plugs old openings after pipeline rerouting.
- closes temporary tapping holes after maintenance or testing.
Application Scenarios of HDPE Electrofusion Blocking/Plugging Saddle for Fuel Gas
- Nodes in urban medium/low pressure gas networks where reserved branches need to be blocked — is the standard fitting for these closures.
