Both Rifeng and Weixing are available. There are pipes that specialize in floor heating, but the price of Weixing will be higher. Poly, generally rarely useful for floor heating.
Floor heating pipe refers to a type of pipe used as a circulating flow carrier of low-temperature hot water in a low-temperature hot water floor radiant heating system (referred to as floor heating).
The raw material for floor heating is a medium-density polyethylene with very stable mechanical properties. It is made of ethylene and octene monomers catalyzed by metallocene polymerization. Its unique ethylene main chain and octene short-chain branch structure enable it to simultaneously possess the superior toughness of ethylene, stress crack resistance, low-temperature impact resistance, outstanding long-term water pressure resistance, and the thermal creep resistance of octene.
