Trace Heating & Insulation
Heat tracing, Trace Heating or Surface Heating is the method of heating and/or maintaining temperatures in pipelines, tanks/ vessels and pipeline equipment. This is done by either mechanical or electrical heat tracing.
Electrical Trace Heating
Series These are composed of two or more resistance wire elements connected to form a series or series-parallel electric circuit. The cables are always individually designed into particular lengths and load configurations for heating of long pipelines. Series circuit heating units are available for operating temperature applications up to 400°C and at power ratings up to 150W/metre.
Constant electric power heating cables combine features of series and parallel resistance heating cables. Their parallel bus wire construction and uniform output characteristics make them easy to apply in the field. These cables are of high quality materials and strong construction at a cost effective price.
Self regulating are the most common form of electric heat tracing cable used in the world today. Applications vary widely including freeze protection of pipework and vessels, process temperature maintenance. Inquire for our range of self-regulating heating cables.
Mechanical Tracing can be done in several ways. Steam or a fluid such as hot water, heating oil or Glycol, is pumped through a tracing pipe that is connected to the process pipe. Bare steam tracing is the most used method as it is easily installed and maintained and it is suited to lower temperature requirements. It is composed of a half inch or three quarters of an inch tubing (Copper or Stainless) strapped to the process fluid pipe and both pipes are then insulated together. The other option is to use cemented steam tracing. Heat conductive cement is placed around the steam tracer running parallel to the process fluid pipe, to increase the contact area available for heat transfer, between the tracer and the process fluid pipe.
