Metal Heat Treatment, PWHT, Pre-Heat, Stress relieving heat induction equipment

Metal heat treatment, Induction heating weld preheating, pwht and stress relieving equipment. Easy to install through cable connection panel that does not require removal of sheet metal.

Multiple output provides two insulated connectors for air-cooled blankets or liquid-cooled cables. Versatile mobility through a lifting eye or optional running gear designed for construction and maintenance. On-board temperature control provides for manual or temperature-based programming in a simple-to-learn operator interface.

Multiple control thermocouple inputs (patent-pending) are available to control on the hottest TC during heating and coolest TC during cooling for uniform heating and quality. Open output detection (patent-pending) prevents system operation without a covered output receptacle (cable or protective plug).

Cable identification system (patent-pending) knows the type of cable attached and limits output to protect cables and blankets. Operator tutoring system provides helpful information to optimize coil arrangements for maximum performance.

Isolation fault protection (patented) provides automatic system shut down should power source output short to ground. A sense lead provides direct feedback to the power source to initiate fault condition.

Low consumable costs. No fuel costs and minimal insulation costs. Insulation is reusable and may be used 50 times or more, reducing cost of disposal.

WB Alloys team of heat technicians are highly experienced in heat treating applications, although the equipment is user friendly we can supply hire equipment with an engineer to set up and monitor for the duration of the job - or can provide training. With heat technicians based in Aberdeen, Glasgow, Newcastle and Tavistock we are able to service the UK.

 

Metal Heat Treatment

Uniform heating is maintained along and through the heat zone by using induction to heat within the material. The surface of the part is not marred by localized conducted heat at higher than specified temperatures. Time-to-temperature is faster than conventional processes due to the method of applying the heat, reducing heating cycle time.

Improved working environment is created during welding. Welders are not exposed to open flame, explosive gases and ho elements associated with fuel gas heating and resistance heating.

Easy set-up is achieved using preheat blankets or flexible heating cables combined with user-friendly insulation blankets. High energy-efficient systems (more than 90% efficient) transfers more energy to the part, decreasing heating times and improving power efficiency (less than 60-amp current draw).

Built-In Temperature Controller

The ProHeat 35 Heat Induction Power Source is equipped with a built-in temperature controller. The controller provides for Manual Programming or Temperature Based Programming. Manual programming provides for setting a power setting and a time duration.

This is beneficial in preheat applications where a part is heated to temperature and the heating device removed. Temperature Based Programming provides the ability to develop procedures for preheating, hydrogen bake-out or stress relieve.

Four control thermocouples and two monitoring thermocouples are provided for heating. The control thermocouples are read by the controller which regulate the heat rise based on the hottest thermocouple and cooling based on the coolest thermocouple.

This capability helps to insure the heating and cooling rates are not violated during the procedure. The controller is designed to be easily understood and programmed.

Pro Heat

The ProHeat 35 Induction Power Source is designed with on-board diagnostics with operator tutoring. Parameters are available at the touch of a button. Induction parameters are highly dependent on how the heating system (blanket or cable) is placed on the part to be heated.

The ProHeat provides for Limit Conditions where a parameter maximum has occurred. The ProHeat will continue to deliver power, notify the operator and then provide helpful information to increase the output.

The ProHeat will also identify Fault Conditions and provide information. The purpose of these capabilities is to provide continuing education of the operator on the use of heat induction equipment and protect the system.

System Configurations

The ProHeat 35 Induction Power Source is designed with two output connectors for either air-cooled blankets or liquid-cooled cables. This capability requires the use of same size air cooled blankets or in the case of liquid-cooled systems, the applications must be the same (same size pipe, same program and same coil). The Cable Identification System is able to detect which type of cables are attached and configures the maximum output for the power source. This to protect cables and blankets from exceeding the rated duty cycle. The outputs are protected through insulated connectors or when not in use, a protective output cap.

Heat Induction Blanket

Miller’s patented flexible induction blanket is the newest innovation in preheat technology from a leader in the welding industry. The flexible, lightweight induction heating blankets come in a variety of sizes and are capable of preheat temperatures up to 400° F (204° C). See Lit. Index No. IN/3.0 for additional information on temperature rating and duty cycle.

The blankets easily conform to circular and flat parts and install in a matter of seconds. Manufactured from durable high-temperature materials, flexible induction blankets are designed to withstand the tough conditions in both industrial and construction applications. Each blanket is supplied with two spare blanket-securing straps and one replaceable Kevlar® sleeve which provides added protection against abrasion, cuts and tears, extending blanket life.

Output Extension Cables and Series Cable Adapter

output extension cable and adapter

Output extension cables are available in 25 and 50 ft (7.6 and 15.2 m) lengths and provide interconnection between the power source and flexible induction heating blanket. This product includes durable twist lock connectors for attachment to the induction blanket. The heat treating power source connection is made using an insulated twistlock connector which also identifies the type of heating device to the power source controller (air-cooled or liquid-cooled system). This cable identification system (patent-pending) prevents over duty cycling of the heating blanket. A special cable-potting process is utilized at the cable ends to assure the product withstands the rugged environment experienced in the industrial and construction markets.

The series cable adapter is used to combine two blankets in series. This enables one power source and one output cable to be used to create extra heating area using two induction heating blankets.

With experienced heat technicians WB Alloys are able to offer a complete package of rental equipment with a technician if required, with facilities throughout the UK we can accommodate works from Aberdeen, Glasgow to Devon and everywhere in-between.
