ASME U-Stamp Carbon Steel Vessel with Insulation Cladding

Yuhong Group: Complete Pressure Equipment Solutions – From Components to Fully Insulated Vessels

Yuhong Group Co., Ltd. designs and manufactures a comprehensive range of thermal and pressure equipment for global industries. Our core offerings include shell and tube heat exchangers, pressure vessels, air coolers, and a complete supply of critical components: finned tube bundles, U-tube bundles, heat exchanger tubesheets, and all related parts – ensuring full support for new projects and maintenance.

Shown in the attached photographs is one of our insulated vertical pressure vessels – a custom-engineered unit designed for process storage, separation, or surge control with thermal insulation to maintain process temperature and protect personnel.

Product Focus: Insulated Pressure Vessel – Engineered for Thermal Efficiency & Personnel Safety

A pressure vessel is a closed container designed to hold gases or liquids at pressures substantially different from ambient. This vessel features external insulation with metal cladding – a critical addition for processes requiring temperature maintenance, freeze protection, or personnel burn protection.

Based on the images, this vessel exhibits:

• Configuration: Vertical pressure vessel
• Material: Carbon steel (ASME SA516 Gr.70 typical) – providing strength and cost-effectiveness
• Construction: ASME Section VIII, Division 1 compliant with U-Stamp certification
• Insulation: External insulation with metal cladding – maintaining process temperature and protecting personnel
• Supports: Skirt or leg supports – designed for vertical installation
• Features: Manways, nozzles, lifting lugs, and insulation cladding
• Application: Process storage, separation, or surge control

Key Components & Their Functions in an Insulated Pressure Vessel

Technical Highlights of Our Insulated Pressure Vessel

• ASME U-Stamp certified: Full compliance with ASME Section VIII, Division 1 – ensuring global acceptance for safety and regulatory requirements.
• External insulation with metal cladding: The insulation layer reduces heat loss (or gain) – maintaining process temperature, improving energy efficiency, and protecting personnel from hot or cold surfaces. The metal cladding provides weather protection and a professional finish.
• Custom engineering: Designed to your specific pressure, temperature, volume, and service conditions.
• Material flexibility: Carbon steel (SA516 Gr.70), stainless steel (304/316L), chrome-moly (F11/F22), clad plate – selected based on service fluid and environment.
• NDE & PWHT: Full NDE (RT, UT, MT, PT) and PWHT as required by ASME code – ensuring weld integrity.
• Hydrostatic testing: Every vessel is pressure-tested before shipment – documented with test reports.

Component-Only Supply – We Also Provide for Maintenance & Spares

If your existing pressure vessel needs replacement parts, we supply individual components without ordering a complete new vessel:

• Dished heads – formed to your dimensions and thickness
• Nozzles and flanges – SA105, SA182 – any facing type
• Internal coils – carbon steel or stainless steel – for heating/cooling
• Manway covers and gaskets – complete access closure assemblies
• Insulation and cladding – replacement or upgrade of existing insulation
• Heat exchanger tubes – cut to length, end-prepared
• Finned tube bundles – for external heating/cooling applications
