Description:

Discover our 1-35KHZ 80KW induction hardening equipment designed for PWHT (Post Weld Heat Treatment) of drill pipes up to 1350°F. Ideal for oilfield applications, it ensures precise temperature control, uniform heating, and compliance with industry standards like API and ASME. Enhance durability and performance of your drilling tools.

Introduction:

Induction heating has revolutionized heat treatment processes in the oil and gas industry, particularly for drill pipes. Our 1-35KHZ 80KW induction hardening equipment is engineered specifically for PWHT (Post Weld Heat Treatment) of drill pipes, capable of heating up to 1350°F (approximately 732°C). This system ensures enhanced mechanical properties, reduced residual stresses, and improved corrosion resistance in drilling equipment. By leveraging advanced solid-state IGBT technology and frequency automation, it delivers energy-efficient, consistent, and reliable performance for critical oilfield applications.

Key Features of the Equipment

• Wide Frequency Range (1-35 kHz):

  • Supports both shallow case hardening (higher frequencies) and deeper penetration (lower frequencies).

  • Automatic frequency tracking ensures stable performance under varying load conditions.

• High Power Output (80 kW):

  • Provides rapid heating rates, reducing processing time and energy consumption.

  • 100% duty cycle allows continuous operation without overheating.

• Precise Temperature Control:

  • Digital PID temperature feedback maintains accuracy within ±5°C.

  • Thermocouple-compatible for real-time monitoring and compliance with PWHT protocols.

• Robust Design:

  • Solid-state IGBT power modules ensure longevity and reliability.

  • Lightweight (≈150 kg) and compact (750×550×800 mm) for easy integration into production lines.

• Safety and Compliance:

  • Built-in protection against over-current, over-voltage, and water cooling failures.

  • Meets API RP 7G and ASME B31.3 standards for drill pipe heat treatment.

Specifications:

Competitive Advantage:

1.Versatile Mobility:optional running gear designed for construction and maintenance
2.On-board temperature control:provide for manual or temperature based programming in a simple-to-learn operator interface
3.Muitiple control thermocouple inputs:available to control on the hottest TC during heating and coolest TC during cooling for
4.uniform heating and quanlity
5.Open output detection:prevents system operation without a covered output receptacle(cable or protective plug)
6.Isolation fault protection:provides automatic system shut down power source output to ground.
7.Low consumable costs:No fuel costs and minimal insulation costs.insulation is resuable and may be used 50 time or more,reducing costs of disposal and replacement.
8.Uniform heating:maintained along and through the heat zone by using induction to heat within the material.the surface of the part is nor marred by localized conducted heat at higher than specified temperatutes.
9.Time-to-temperature:faster than conventional processes due to methed of applying the heat,reducing the heating heating recyle time.
10.Improved working environment: With welding,welders are not exposed to open flame,explosive gases and hot elements associated with fuel gas heating and resistance heating.
11.High energy-efficeent systems:(more than 90 percent efficient)transfers more energy to the part,decreassing heating times and impoving power efficietnt.
12.Easy Set-up:achieved using preheat blankets or flexible heating cables combined with user-friendly insulation blankets.
