YUHONG is a premier provider of high-specification equipment for the global oil, gas, and petrochemical sectors. We excel in the design and fabrication of ASME U Stamp Certified pressure components, ensuring that every product meets the most rigorous international safety and quality standards.
Our products are engineered and manufactured in strict accordance with the ASME BPV Code, the international benchmark for pressure equipment safety and quality. The code is organized into the following specialized sections:
Sec. I: Power Boilers
Sec. II: Materials
Sec. III: Nuclear Fuel Containers
Sec. IV: Heating Boilers
Sec. V: Non-Destructive Examination (NDE)
Sec. VI: Recommended Rules for the Care and Operation of Heating Boilers
Sec. VII: Recommended Guidelines for the Care of Power Boilers
Sec. VIII: Pressure Vessels
Sec. IX: Welding and Brazing Qualifications
Sec. X: Fiber-Reinforced Plastic Pressure Vessels
Sec. XI: Rules for Inservice Inspection of Nuclear Power Plant Components
Sec. XII: Rules for Construction and Continued Service of Transport Tanks
We specialize in the design and construction of vessels following ASME Section VIII, which is categorized by pressure requirements and design methodologies:
Division 1 (Div. I): Standard pressure vessels for internal or external pressures up to 3,000 PSI. Design is based on established "Design by Formula" rules.
Division 2 (Div. II): Alternative rules for pressures up to 10,000 PSI. This utilizes "Design by Analysis," allowing for more precise calculations and often resulting in more economical, lighter-weight vessels for higher pressures.
Division 3 (Div. III): Alternative rules for High-Pressure Vessels designed for pressures exceeding 10,000 PSI.
To ensure full compliance and traceability, our documentation follows the structured subsections of Section VIII, Div. 1:
Subsection A: General Requirements (UG) covering all methods of construction and all materials.
Subsection B: Specific requirements based on Methods of Fabrication, including:
Welding (UW)
Forging (UF)
Brazing (UB)
Subsection C: Specific requirements based on Classes of Materials, including:
Carbon and Low Alloy Steels (UCS)
High Alloy Steels (UHA)
Heat Exchanger specialized parts (Part UHX)
Mandatory Appendices: Essential rules for specific design types or inspection methods.
Non-mandatory Appendices: Supplemental information and recommended practices.
In addition to the core ASME Codes, we integrate specific industry and client standards to meet diverse project requirements:
Primary Codes: ASME BPV-SEC. VIII, DIV. I & ASME BPV-SEC. II
Contractor & Owner Specifications: We are experienced in adhering to stringent internal standards such as:
Foster Wheeler company design manuals
IPS (Iranian Petroleum Standards)
NIOC (National Iranian Oil Company) standards, and other regional or company-specific technical requirements.
