Steam Pipe Insulation Specification

Standard specification for calcium silicate block and pipe thermal insulation.

Steam pipe insulation specification.

Available as flexible blanket rigid board pipe covering and other pre molded shapes. Piping systems designed for steam pressures from 25 psig up to and including 125 psig are medium pressure steam. The integral lap ensures fast and easy installation. They come in a wide range of nominal pipe sizes nps from 2 to 24.

Very hot systems like hot water and steam systems should also be insulated to avoid potential personal injuries. Rocklap h v pipe sections are strong lengths of pre formed insulation with a one piece factory applied foil facing with integral self adhesive lap. Standard specification for mineral fiber pipe insulation. Rock and slag fibres are bonded together with a heat resistant.

Systems 126 psig and above are high pressure steam. Distribution piping complying with thermal energy cooperative teco requirements is. It doesn t matter what type of heating system you have your steam steam condensate and hot water heating pipes should all be insulated with fiberglass pipe insulation. If specified on contract drawings all insulated exposed vertical piping within the building and all insulated piping exposed to the outdoors shall be additionally jacketed with 0 016 thick 0 4 mm minimum aluminum.

Presently most industry designs aim at a touch temperature outer surface of the insulation at 140 f or less. Just snap the sections onto the pipe peel off the backing tape and smooth down for a completely sealed joint. Industrial insulation phase 2 5 pipe insulation hot cold material selection application revision 2 0 august 2014 mineral fibre glass. Service temperature range is up to 535 c.

Since the steam velocity must not exceed 25 m s the pipe size must be at least 130 mm. Again a nomogram has been created to simplify this process see figure 10 2 8. This specification is one of a series prepared by the defence estate organisation primarily for use in its contracts for mechanical and electrical engineering works. The table below indicates recommended insulation thickness.

The specification covers the. Ideal for use on steam and high temperature applications. Piping systems designed for steam pressure below 25 psig are low pressure steam systems. Vertical piping shall be protected to a height of 8 0 2 4 m above the floor.

Standard specification for cellular glass thermal insulation. In general there are no insulation thickness requirements for residential heating pipes but we find that a minimum of 1 thickness is cost efficient in most scenarios. Thermaxx jackets steam pipe insulation jackets are easily installed removed and replaced requiring no special skills.
