Industry Code: 30407
This industry includes businesses that specialize in the heat treating of metal/steel and the cleaning and coating of pipes.
Heat treating metal changes the characteristics of the metal to make it more suitable for a desired or particular application.
Pipe Coating requires highly automated in-shop services for cleaning and applying a protection/insulation cover on various lengths and widths of the pipe.
Operation Details:
With heat treating/stress relieving, metal can be heated to harden or strengthen the metal, or heat treated to soften it in order that work may be done such as machining. Heat treating and stress relieving services can be either a plant or mobile operation. In plant situations, heat treating is used on a variety of metals such as alloy steel, castings, aluminum alloys and stainless steel. Some of the metal items which require heat treating are shafts, bearings, gears, bolts, axles and pipe.
The following is a list of equipment that may be found at a heat treating plant:
- pit furnaces
- gas carburizing furnaces
- salt bath furnaces
- thermonic heat treater
- global furnaces
- electrical monorail crane
- electrical overhead crane
- metal hardness testers
The first step in heat treating metal is to determine the temperature that must be reached to make the structural change to the metal. To reach the temperature required, the metal is heated by natural gas, heated solutions or with electricity. Once this temperature has been sustained, the metal is then cooled in oil, water, a salt bath solution or by air; then the metal is reheated and cooled again.
Mobile operations are used as a pre-heating application to facilitate a welding process, or as a post-weld treatment to relax any stress created in the surrounding metal by the welding process itself. Self-contained mobile units use computerized control equipment to monitor electric heating elements which are wrapped around the welded area.
With pipe coating, the pipe is cleaned by chemicals and/or high pressure blasting. The pipe is then manoeuvred by rollers/conveyors/forklifts into the coating machine. As the pipe moves through, the coating effectively 'melts' over the pipe and is then quickly cooled. At various stages of production are pipe inspectors (most often contracted to an oil company) to ensure the coating is proper and correct in composition and thickness.
Pipe coating and cleaning businesses will use rollers, conveyors, forklifts and applicators in an automated environment and may employ technical staff, shop workers, labourers and sales, office and administrative staff.
Underwriting Considerations:
Mobile heat treating/stress relieving operations may also use gas fire burners. Mobile operations are used on metal fabrications in oil refineries, gas plants, pulp mills, etc.
Steel fabrication shops and machine shops may have heat treating capabilities and may conduct some custom heat treating services, but it is deemed part of the main business.
Pipe coating services conducted exclusively in the field are described in industry 42139, Industrial Coating Services. Electroplating decorative and auto parts is classified in industry 65800, Automobile Body Repairs. Electroplating and galvanizing other than auto parts is classified in industry 30403.
Industry Custom Pricing: Waiving Cost Relief Option
This industry has chosen to participate in Industry Custom Pricing effective January 1, 2010. Costs related to the aggravation of a pre-existing condition will not be removed from the experience record of employers classified in this industry. In return, the portion of premiums collected to fund retroactive cost relief has been removed from the industry rate, resulting in a reduction in WCB premium rates for the industry.
