ANSI Pipe Marking Standards and Pipe Color Codes - Quick

Pipe marking labels must effectively communie the contents of the pipes and give additional detail if special hazards (such as extreme temperatures or pressures) exist. The legend should be short in length and easy to understand. For example, the legend "Steam 100 PSIG" specifies the contents as well as the additional pressure hazard.

The Polyethylene Casing as Diffusion Barrier for

The permeability of the cell gases (oxygen, nitrogen, carbon dioxide and cyclopentane) in the PUR foam and in the HDPE casing was determined for a temperature range of 20–60 C (PUR) and 5–40 C

The Polyethylene Casing as Diffusion Barrier for

Most district heating pipes are insulated with polyurethane foam in order to minimise heat losses. A high-density polyethylene (HDPE) casing protects the insulated pipe, and its permeability properties for the polyurethane cell gases, including air, play an important role for the long-term insulating capacity.The permeability of the HDPE casing of a district heating pipe was studied.

Analysis of ductile and brittle failures from creep

For both pipes, the ‘knee’ or the transition from ductile failures at high stresses to brittle failures at low stresses is clearly evident. Specifically, the knee for HDPE-D occurs at much longer times compared to that of HDPE-A. This indies that the HDPE-D pipe is generally more resistant to SCG failures compared to the HDPE-A pipe.

Accelerated ageing and degradation characteristics of

The urgent need for revision of the normative test method (EN 253) for the lifetime prediction of district heating pipes requires a better understanding of the failure mechanisms involved. Therefore, various methods were used to study thermal degradation characteristics of rigid polyurethane (PUR) foam in both air and nitrogen atmosphere.
