Controlled PWHT Solutions for Welded Steel Components

At Premium Plate, post weld heat treatment eliminates excessive stress in welded steel assemblies. It refines microstructure and improves toughness and ductility. Integrated with our fabrication workflow, this capability supports fast, efficient delivery of large tank and vessel sections, including shell plates, nozzles, manways, and inserts. All work complies with API 650 and industry inspection standards.

PWHT Capabilities and Processing Advantages

Premium Plate performs post weld heat treating services in a dedicated, controlled oven engineered for large assemblies. The heavy-duty oven capabilities with repeatable metallurgical outcomes let us reliably process full weldments and large plates with minimal handling. These capabilities support code compliance and third-party inspection requirements.

Specifications:

  • Oven dimensions are 11 ft tall × 14 ft wide × 48 ft long, for specialized, heavy-load components.
  • A 50-ton crane for loading heavy assemblies.
  • Capable of PWHT for carbon and stainless steel shell plates, nozzles, manways, inserts, and complete welded assemblies.
  • Designed to meet API 650, applicable ASME, and industry codes.

Benefits:

  • PWHT relieves residual weld stress and reduces the risk of cracking and distortion in service.
  • Ensuring the uniform metallurgical properties across welds and parent metal.
  • Improving dimensional stability and providing long-term durability with better structural performance.
  • Reducing rework and accelerating field installation when combined with in-house cutting, forming, and coating.

FAQs About Post Weld Heat Treat

Yes, Premium Plate integrates PWHT with plate supply, cutting, beveling, forming, and coating for a single-source fabrication solution that reduces handling and other costs and speeds up the delivery.
We can effectively handle both. At Premium Plate, we do single plate and welded assemblies, such as shell sections, manways, and nozzles, to the API 650 requirements.
At Premium Plate, we have an 11 ft high x 14 ft wide x 48 ft long heat-treat oven, attended by a 50 ton crane, which will enable us to work conveniently on large shell sections, nozzles, and inserts.
Please provide the material specification, weld thickness, dimensions, required temperature range, and applicable code so we can prepare an accurate, traceable quote.
Premium Plate carries out post weld heat treatment services in compliance with API 650, ASME, and client-specific code provisions of tanks and pressure holding parts.
