Pipe Insulation Types Pdf

Pipe insulation can prevent condensation forming as the surface.

Pipe insulation types pdf. Insulation adjacent to flanges in piping and equipment shall be terminated to allow removal of bolts without damage to insulation. R values vary based on the type thickness and density of the insulation material. Product data mechanical solutions brochure february 2020 5 used to insulate iron copper pvc and other polymer pipes with operating temperatures between 0 f 18 c to 1 000 f 538 c in commercial institutional. It is typically used in process piping and chiller plants and performs best in applications below 50 f.

Board blanket pipe covering. This very rigid insulation offers the lowest heat flow rate of our pipe insulation and restricts absorption of water air and gas. 315 c through 815 c i e. Calcium silicate pipe and block insulation are covered in astm c 533.

Fibrous insulation composed of small diameter fibers which finely divide the air space. They become useless on increasing temperature. 1 2 insulation types insulation materials are generally divided into three main types. The standard contains three types classified primarily by maximum use temperature and density.

Types i ii iii iv. R value measures how resistant types of insulation are to heat flow. These types of pipes have good resistance against electric current. The asbestos pipe is made from asbestos silica and cement converted under pressure to a dense homogeneous material possessing considerable strength.

Astm c547 mineral fiber pipe insulation types i grade a. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. Moisture is known to contribute towards many different types of corrosion so preventing the formation of condensation on pipework is usually considered important. Turbines breechings stacks exhausts incinerators.

Where pipes operate at below ambient temperatures the potential exists for water vapour to condense on the pipe surface. High temperature thermal insulation 1. Calcium silicate thermal insulation is defined by astm as insulation composed principally of hydrous calcium silicate and which usually contains reinforcing fibers. And type iv grade b astm c585 inner and outer diameters of thermal insulation for nominal sizes of pipe and tubing astm c1136 flexible low permeance vapor retarders for thermal insulation.

Industrial insulation phase 2 4 pipe insulation hot cold material selection application revision 2 0 august 2014 c. The fibers may be perpendicular or parallel to the surface being insulated and they may or may not be bonded together. All insulation shall be covered with weather protection designed and installed to prevent ingress of water during normal operation throughout the design life. Silica rock wool slag wool and alumina silica fibers are used.
