COLD SHOES, COLD BLOCKS AND HOT SHOES IN OUR ...

We are proud to deliver high-quality, engineered pipe support solutions on a timely basis to our customers &#; here is a look inside our assembly, inspection & packing bay this week. Cryogenic pipe supports (cold shoes & cold blocks), as well as hot shoes (up to 48&#; pipe size), are destined for overseas LNG and Petrochemical projects.

In order to assign cryogenic pipe supports to a piping system one must first identify why the pipe needs to insulated in the first place. Next is to identify the environmental conditions in which the pipe exists. Thirdly, selection of appropriate insulation and exterior materials. And lastly perform a heat gain calculation.

In the first step, the planner needs to identify why the LNG pipe is in need of being insulated. The two most common reasons for insulating LNG pipes are to minimize condensation on the outer surface of the insulation system, limit heat input to the LNG within, and control the processes that cause sublimation of the liquid within the piping. A common rule of thumb in the cryogenic pipe support industry is to limit the heat gain by the insulation system to the outer shell area of &#;&#;&#;8 Btu / hrft2 (25 W / m2). There are other possible purposes but most of them are achieved by addressing these two.
