Piping PUF insulation and fittings is a rigid structure "pipe in pipe" consisting of steel or galvanized steel carrier pipe, a layer of polyurethane foam insulation and the outer jacket pipe protective of high-density polyethylene - for underground installation or sheet galvanized steel - for above-ground pad.

Rigidity due to the presence of strong ties between the steel pipe layer polyurethane insulation and jacket pipe and provides pre-shot blast or blast cleaning the surface of the steel pipe, optimum performance polyurethane insulation, corona surface of polyethylene pipe shell.
The mold uses a spiral structure, high-quality alloy steel forging ; Temperature control of mold core adopt electric heating .Temperature control have high precision , oil guide copper tube will not aggregate carbon . Heating ring distribute in more area , temperature adjustment for each area of the mold is controllable .
