Heat Treatment Support for Welded Assemblies

Krueger Engineering offers post weld heat treatment services as an important part of fabricating high-performance tanks, vessels, and related components. This process helps welded assemblies meet project-specific mechanical and code requirements while improving long-term reliability in demanding service conditions. By offering heat treatment, we maintain better control over scheduling, handling, and processing for items such as nozzles, man-ways, and inserts. Our team focuses on delivering consistent thermal processing that supports material performance, weld integrity, and overall fabrication quality.

Post Weld Heat Treat Capabilities and Advantages

Our heat treat capability is built to support large fabricated assemblies, tighter production control, and more efficient coordination across demanding industrial work.

Heat Treat Capacity and Processing Features

  • API 650 Support: Offered to help meet the requirements associated with API 650 tank fabrication.
  • Large Oven Envelope: Heat treat oven measures 20 feet tall, 20 feet wide, and 60 feet long for substantial fabricated components.
  • Heavy Handling Capacity: Furnace operation is serviced by a 50-ton crane for controlled movement of large assemblies.
  • Integrated Fabrication Scope: Supports related insert needs as well as supplied nozzles and man-ways within the same service environment.
  • Large-Part Readiness: Aligned with fabrication programs that involve tank components and other sizable welded assemblies.

Project Benefits of PWHT

  • Fewer Outside Hand-Offs: Keeping PWHT post weld heat treatment can simplify scheduling and reduce coordination with third-party processors.
  • Cost Efficiency: Combined services can create significant cost savings by consolidating fabrication and heat treatment under one roof.
  • Large Assembly Support: A practical option for substantial welded fabrications that need thermal processing without fragmented logistics.
  • Tank Fabrication Alignment: Supports projects where post weld heat treatment PWHT is part of broader tank-related production requirements.
  • Material Flexibility: Krueger’s broader materials expertise includes carbon steel, stainless steel, nickel alloys, and duplex materials, which supports work involving post weld heat treatment carbon steel and other alloy-driven fabrication programs.
  • Single-Source Execution: Customers can work with a single PWHT company for heat treat processing, along with fabrication support, inserts, nozzles, and man-ways.

Our integrated thermal processing ensures that your equipment is structurally optimized and ready for the most demanding field conditions.

Frequently Asked Questions About Post Weld Heat Treat

Post weld heat treatment for carbon steel and other welded materials is typically specified when a project must meet code, material, or service requirements tied to stress relief, hardness control, or long-term performance.
Yes. In many projects, post weld heat treatment services are most efficient when they are coordinated with fabrication, welding, and component preparation in the same production workflow.
No. Depending on the application, projects may involve carbon or stainless steel, with requirements determined by material grade, thickness, service conditions, and applicable specifications.
Key considerations usually include material type, weld thickness, component size, code requirements, temperature range, hold time, and whether the project involves PWHT stainless steel or other materials with more specific process demands.
