Here, we delve into the technical processes, benefits, and applications of Banline's advance supplier for Large diameter Thermoplastic Composite Pipe (TCP) Non-metallic End-Fitting Solutions.

Method 1 The Technical process for high-pressure electrofusion coupler & end-fitting – TCP-electrothermal

fusion fitting.

1. Before using the TCP- electrothermal fusion heating end-fitting, the surface layer of the fusion

bonding area should be polished to remove the oxidized layer.

2. The electrothermal fusion pipe fittings contain inner ring copper hot melt wire, the inner ring and

the outer layer of fiberglass tape composite pipe are electrothermally fused. The inner ring hot melt

wire are connected with the positive and negative terminals of pipe fittings. The heating fused glass

fiber tape composite pipe fitting provides the solution to solve the high pressure pipe (4Mpa)

connection.

Method 2 - Electrofusion Coupler & End-Fitting

TCP-electrothermal fusion fittings ensure a secure and efficient pipeline connection, ideal for high-pressure applications. Here's an optimized step-by-step guide to the two-step process, designed for SEO performance and clarity:

Two-Step Process for Leak-Free Connections:

1. Butt-Welding the Liner Pipe: Achieve a 100% leak-free connection by butt-welding the liner pipe ends, resulting in a fully integrated plastic connection.

2. Electrofusion of In-Line Coupler: Strengthen the connection with the centrally placed in-line coupler through electrofusion.

3. 
   

Detailed Technical Process:

1. Scraping the Pipe Surface: Begin by scraping the pipe-end cover layers to expose a fresh PE surface, essential for welding the in-line coupler electrofusion sleeve.
   

2. Loading the Pipe into the Welding Frame: Clean the in-line electrofusion sleeve thoroughly and slide it over one pipe end. Load the pipe-end with the in-line coupler and the second pipe end into the welding frame.

3. Trimming the Pipe Ends: Use trimming tools to ensure both pipe-end faces are properly prepared, creating a small length of free liner pipe necessary for butt-welding.

4. Butt-Welding the Liners: After trimming, remove any burrs and insert a heating plate for around 60 seconds to heat both pipe ends. This ensures a robust bond when the pipe ends are welded together.

5. Welding the Electrofusion Sleeve: Allow the initial weld to cool for about 8 minutes. Slide the in-line coupler electrofusion sleeve centrally over the butt-weld and energize the copper heating coil for about 4 minutes to fuse the sleeve to the pipe connection.

6. Cooling the Connection: Once the electrofusion process is complete, let the connection cool for approximately 30 minutes to ensure maximum strength and durability.
