LPG Distribution HDPIR Pipe Insulation Supports With Single Vertical Plate
HDPIR pipe support with single vertical plate, sliding pipe support
Sliding Pipe Support System is primarily designed for supporting insulated pipes and equipment. A complete insulated pipe support system consists of insulated pipe supports and cold insulation materials, with high-density polyisocyanurate (HDPIR) being the most critical component.

HDPIR is a foaming polymer combining characteristics of plastic, rubber and cork. Composed of isocyanate, polyether, foaming agent, catalyst and flame retardant, it forms a cellular structure with millions of tiny, uniform sealed cells. This structure provides low density, excellent thermal insulation, and minimal water absorption, outperforming traditional timber materials.
