About Post-Weld Heat Treatment Furnace

Post-Weld Heat Treatment Furnace manufactured by United Enterprises is a heavy-duty industrial furnace engineered for stress relieving, normalising and tempering of welded fabrications pressure vessels, pipelines, structural assemblies and heavy weldments.

Short Description:

Post-Weld Heat Treatment (PWHT) is mandated by ASME, EN, IBR and other applicable codes for many welded fabrications to relieve residual welding stresses, restore ductility in the heat-affected zone and ensure long-term reliability under pressure and fatigue. Our PWHT Furnaces are built with heavy-duty refractory, multi-zone burner or electric heating systems, and tight temperature uniformity (commonly within 14C as per code requirements).

Configurations include bogie / car-bottom, top-hat (hood), walk-in chamber and pit designs. Both electric and recuperative gas-fired heating versions are available, with high-efficiency recuperators for fuel saving. SCADA-based recipe management, chart recorders and multi-point thermocouple harnesses ensure full traceability and code compliance.

Each PWHT furnace is engineered around the customers component size, weight, ramp / soak profile and applicable code. We also undertake site PWHT services through localised heating and insulation when components cannot be moved.

Characteristics:

Designed for PWHT of welded fabrications per ASME / EN / IBR codes
Maximum temperature up to 750C (typical PWHT range 580C720C)
Bogie / car-bottom / top-hat / walk-in / pit configurations
Available in electric and recuperative gas-fired versions
Tight temperature uniformity within 14C (or as per code)
Air-recirculation fans for uniform heat distribution
Multi-zone PLC and SCADA temperature control
Multi-point thermocouple harnesses and chart recorders for traceability
Low-density high-quality refractory insulation
Heavy-duty bogie / rail design for large weldments

About United Enterprises:

United Enterprises is over 25+ years experienced Post-Weld Heat Treatment Furnace manufacturer in India. We design, manufacture, supply, export and commission tailor-made PWHT Furnaces across Asia and Europe. Established in 1998, we are an established manufacturer and exporter in India, recognised among top furnace suppliers in India, supplying pressure vessel fabricators, pipeline contractors, defence, shipbuilding and heavy engineering industries all under CE and ISO standards.

FAQs:

Q: Which PWHT temperature should I use?

A: PWHT temperature depends on parent material and applicable code commonly between 580C and 720C for carbon and low-alloy steels. Our team helps you finalise the ramp, soak and cooling profile per ASME, EN or IBR requirements.

Q: Bogie or top-hat PWHT furnace which suits me?

A: Bogie / car-bottom designs are ideal for heavy fabrications where the load is rolled into a stationary furnace. Top-hat (hood) designs are useful when the fabrication is too heavy to move and the furnace is lowered over the load on a fixed base.

Q: Do you provide code-compliant documentation?

A: Yes. We provide temperature uniformity surveys (TUS), calibration certificates, chart records and process documentation aligned with ASME, EN and IBR requirements supporting the customers third-party inspection and code certification.

Reliable Heat Treatment for Superior Weld Quality

With heating elements crafted from high-grade nickel-chromium alloy and advanced insulation materials, the furnace ensures excellent energy efficiency and longevity, making it the preferred solution for demanding industrial environments.

Advanced Automation for Precise Control

Equipped with a PLC/SCADA-based automatic control system, this furnace facilitates precise management of heating and cooling cycles, guaranteeing tailored thermal processing for every job. Operators benefit from intuitive monitoring, customizable programs, and integrated safety features such as over-temperature protection and emergency shutdown systems.

FAQ's of Post-Weld Heat Treatment Furnace:

Q: How is temperature uniformity maintained within the Post-Weld Heat Treatment Furnace?

A: The furnace utilizes high-grade nickel-chromium alloy heating elements and sophisticated airflow design to ensure consistent temperature uniformity within 5C throughout the heating chamber, regardless of load size or configuration.

Q: What is the typical process for using this PWHT furnace?

A: Begin by loading the welded metallic components into the chamber. Select the desired program through the PLC/SCADA control system, adjust heating/cooling rates (up to 300C per hour), and initiate the automated cycle. The furnace heats to the specified temperature, holds as required, then undertakes a controlled, programmable cool-down phase.

Q: When should post-weld heat treatment be applied to welded structures?

A: Post-weld heat treatment is typically conducted after welding operations to relieve residual stresses, modify microstructure, and enhance the durability of metallic joints. Timing depends on material type, industry standards, and project requirements.

Q: Where can this furnace be installed and what are the power options?

A: It is suitable for installation in industrial workshops or fabrication facilities. The furnace supports both electric (380-415V) and fuel-fired (gas or oil) power configurations, allowing flexible integration based on site infrastructure.

Q: What safety features are included with this furnace?

A: Safety is paramount-features include over-temperature protection, an emergency shutdown system, robust chamber construction, and operator-friendly manual or motorized door operation ensuring secure handling throughout the process.

Q: Why is this furnace beneficial for heat treating welded joints?

A: Its precise temperature control, uniform heat distribution, and advanced automation optimize metallurgical properties and minimize distortion or cracking, resulting in reliable, high-quality welds fit for demanding applications.
