Fine PolyFusion Co.,Ltd.’s new factory

Because the large requirements of large diameter hdpe fusion machine/ poly fusion machines both in Domestic and international market, We now has a new factory which produce large diameter hdpe fusion machine/ poly fusion machines in Zhuji Shaoxin City. This location provides us with a base for plant & equipment and personnel to service water pipeline construction projects in Zhuji  and Ningbo.

Especially, it’s very convinient for us to export hdpe fusion machine/poly fusion machines from Ningbo to the world.

What pipe sizes will our machines fuse?

Most our fusion machines have a number that shall give you a certain range of the equipment according hdpe pipe.The largest diameter fusion machine is Model GDC 1200-1600 hdpe fusion machine will fuse 1200mm to 1600 mm pipe size. With different size of Fine Polyfusion’s fusion machines, you can fuse from 63mm to 1600mm pipe sizes.

How can a poly fusion machine weld hdpe pipes ?

The poly fusion machine or hdpe fusion machine is applied to weld hdpe pipe  both in the water and gas supplier, and from pp and PVDF for the chemical industries and minerals industry. The pipes are put into the clamps of poly fusion machine or hdpe fusion machine and checked for initial alignment. The two hdpe pipes’ ends are then cut to make sure that they are clean and flat. The end of  alignment for the hdpe tubes is rechecked. The welding sequence begins when a heating plate, at a preset temperature, is positioned between the two pipe ends. The pipes are pushed together with each other until the pipes’ ends come into contact with the hot plate and the pressure is increased to give good thermal contact. The pipe ends melt and the interface pressure forces the molten material outwards to form ‘weld beads’ at the outside and inside pipe surfaces; hence the term ‘bead-up’ stage. At the end of this stage, the pressure is reduced to a value sufficient only to maintain the pipe in contact with the hot plate. This allows the melt depth to increase without increasing the size of the weld beads. At the end of this ‘heat soak’ stage, the pipe ends are pulled away from the hot plate. The heating plate is removed, and the two fused pipe ends are pushed together at the same pressure as used during the initial bead-up stage. This causes further growth of the weld bead and is called the ‘bead roll over’ stage. The power is maintained until the welding procedure is completely cooled down.Poly Fusion machine or hdpe fusion machine for welding thermoplastic pipes can be carried out on a wide range of pipe sizes, absolutely between 63 and 1600mm DN. Manually, automatically and semi-automatically poly fusion machine or hdpe fusion machine is available commercially from Fine PolyFusion Co., Ltd..

What is poly fusion machine ?

Poly fusion machine named hdpe fusion machine too, is used to make poly pipe end to end joints. When using poly fusion machine or hdpe fusion machine joining of poly pipe needs that the two faces are square to each other and readily prepared. The two faces are heated and fused with a heating plate meanwhile. The heating facer is then removed and the fused faces are pushed together and held with pressure. As the fused faces are pushed together, the fused ends mix and once cooled, they fuse into a piece joint forever which has simlar strength as the poly pipe itself in both tensile and pressure properties. So a poly fusion machine or hdpe fusion machine is the best tool for fusing poly pipe.
