Durcor Pressure / Temperature

Special vent couplings are available for pipe with insulation. 1/8” NPS half couplings can be supplied and pipe nipples of sufficient length can extend through the insulation cover.

Designed for Longevity

We have included some basic design data to determine if Durcor® piping system meets your principle requirements. For more engineering data on expansion, end loads from restrained thermal expansion, minimum offset leg requirements, etc., please refer to Durcor® piping design & specification guide, brochure Eng-2100.

Unsupported Span (Feet) at Various Fluid Temperatures
*Note: These values consider maximum 0.5” mid-span deflection. These values do not take into account concentrated loads from flanges

Fluid Flow

Fluid Flow

All Durcor® flanges (pipe & fittings) have a serrated face to aid against cold flow (creep) or flare distortion during temperature cycling.

Standard flange drilling is ANSI B16.5 Class 150 DIN PN10/PN16, JIS B2220 5KG/10KG also Available
