Pipe filling can be made by selecting two-component low-pressure foaming machine for pipe filling, and two-component high-pressure foaming machine for pipe filling. The picture of the machine is as follows:

Pipe low foaming machine is the liquid filling two components polyols and isocyanates two component raw materials stored separately in two material storage tank, with two rotary precision gear metering pump to the mixed system, the pressure under the action of mixing head open, two components were injected into the small in the mixing chamber, a mixing blade high speed stirring and mixing effect, make the material liquid evenly, to form the required product.

Equipment application: this model is suitable for production of direct buried polyurethane insulation pipe, thermal pipe, pvc-ppr polyurethane insulation pipe and other products.

Pipe high pressure foaming machine fill two components is the liquid polyols and isocyanates two components of the raw materials respectively stored in two material storage tank, by two rotary axial plunger metering pump (radial) sent to the mixed system, under the action of hydraulic mixing head open, two components was injected into the small mixing chamber with a high speed, after high speed collision and mixing effect, make the material liquid evenly, mixing effect is good, no clean, stable performance, easy operation, achieve the goal of high production efficiency and environmental protection. This model is suitable for the production of direct buried polyurethane insulation pipe, thermal pipe, pvc-ppr polyurethane insulation pipe and other products.
