What is butt fusion? And what are its advantages?

Butt fusion is a thermofusion process and it involves the simultaneous heating of the ends of two pipe/fitting components which are to be joined, until a molten state is attained on each contact surface. The two surfaces are then brought together to form a stable fusion joint.

Butt fusion can form stable and reliable joints with easy operations. It is often used for jointing PE, PP, PVDF, HDPE, MPP pipes.

Can butt fusion be used to joint different types of plastic pipes?

Because different plastic pipes have different heating time and heating temperature, butt fusion is not a good choice for jointing different plastic pipes.

Guide to butt fusion jointing

In order to achieve an acceptable joint, three preparation works are essential:

• Identify the pipe diameter to be processed and select a proper butt fusion equipment.
• Check the wires on site to see whether it is matchable with the machine motor.
• Execute test welding to examine the butt fusion welding performance prior to formal welding.

Applicable pipe materials and welding process for PE/HDPE pipes

Butt fusion is applicable to PE, HDPE, PP, PVDF, MPP pipes.
Butt fusion welding process for PE/HDPE pipes

• Power and test your butt fusion equipment.
• Cut the plastic pipes into desired length.
• Fix the cut pipes into the clamping tool.
• Plane the pipe end and ensure two pipe ends to be jointed can align with each other.
• Clean the pipe end and heat the end until its surface melts using the heating plate.
• Take out the heating plate, bring two molten ends together under controlled pressure for a specific cooling time until a homogeneous fusion joint is formed.

How is the butt fusion joint quality?

butt fusion can create stable and firm fusion joint with excellent pressure resistance performance.
