Stud Bolts
Precision Engineered Stud Bolts for Demanding Industrial Applications
As an experienced stud bolt manufacturer, Kao Wan delivers robust fastener tailored to global industrial standards. Our custom stud bolt production focuses on exacting specifications, material integrity, and performance reliability across critical sectors like petrochemical plants, power generation facilities, and heavy machinery assembly.
Technical Specifications & Material Excellence
Kao Wan's stud bolts are manufactured using grade-certified raw materials, including ASTM A193 B7/B16 alloy steel, stainless steel (304/316), and duplex steel. Each custom stud bolt undergoes precision threading (UNC/UNF/metric) and heat treatment to achieve tensile strengths up to 150 ksi. Available in diameters from M6 to M100 and lengths up to 3 meters, our products meet ASME B16.5, DIN, and JIS specifications for flange connections in high-pressure environments.
Industry-Specific Adaptability
Designed for extreme conditions, our stud bolts serve LNG pipeline systems requiring cryogenic toughness (-196°C), offshore platforms with anti-corrosion coatings, and thermal power plants needing sustained performance at 600°C+. Clients in the semiconductor sector utilize our non-contaminating electropolished variants for ultra-clean vacuum chambers.
Certifications & Quality Assurance
Kao Wan holds ISO 9001:2015 certification and complies with CE marking directives for pressure equipment (PED 2014/68/EU). Third-party testing reports for Charpy impact, hardness (HRC 22-34), and salt spray resistance (1,000+ hours) validate product durability.
Customization Capabilities
As a trusted partner for OEMs, we provide custom stud bolt services including:
- Tailored lengths with rolled or cut threads
- Zinc-nickel plating, Xylan coatings, or hot-dip galvanizing
- Non-standard thread pitches for legacy machinery retrofits
- Traceable batch testing with material certificates (3.1/3.2 EN 10204)
Proven Performance
Recent projects include supplying 2,500 sets of B7M stud bolts for a Middle Eastern refinery expansion and developing low-profile flange bolts for modular nuclear reactor prototypes. Over 85% of clients report zero fastener failures during 5-year maintenance cycles.
