Shanxi Xinshunda Flange Manufacturing Co., Ltd. delivers high-performance ANSI B16.5 Class 150 flange solutions designed for demanding industrial pipeline systems. Our precision-engineered components ensure leak-proof connections and long-term reliability across global infrastructure projects. With nearly two decades of manufacturing excellence, we serve as a trusted partner for energy, chemical, and water treatment sectors worldwide.
Advanced Engineering and Material Excellence
Our ANSI B16.5 Class 150 flange product line features superior metallurgical properties tailored for moderate pressure applications. Manufactured from premium carbon steel (A105), stainless steel (F304/F316), and alloy steel (F11/F22), each component undergoes rigorous heat treatment and CNC machining processes. The Class 150 rating provides optimal performance at temperatures ranging from -20°F to 800°F, with pressure capabilities up to 285 psi at ambient conditions.
Key technical specifications include:
- Strict adherence to ANSI B16.5 Class 150 flange dimensional standards
- Available sizes from 1/2 inch to 24 inch nominal pipe diameter
- Multiple face configurations: Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ)
- Surface finish quality between 125-250 µin Ra for optimal gasket sealing
- Full traceability with EN 10204 3.1 Material Test Certificates
Versatile Industrial Applications
The ANSI B16.5 Class 150 flange serves critical roles in diverse operational environments. Oil and gas transmission networks rely on our components for secure pipeline joints, while chemical processing plants utilize their corrosion-resistant variants for aggressive media handling. Power generation facilities integrate these flanges into steam systems, and municipal water authorities depend on their durability for distribution networks. Additional applications span marine engineering, HVAC systems, pharmaceutical manufacturing, and food processing lines where hygiene and reliability are paramount.
Comprehensive Quality Assurance Protocol
At Shanxi Xinshunda, every ANSI B16.5 Class 150 flange passes through a multi-stage quality verification process. Raw materials receive mill certification before production begins. Dimensional accuracy is verified using coordinate measuring machines, while visual inspections detect surface imperfections. Hydrostatic testing validates pressure integrity according to ASME standards. Our ISO 9001-certified facility maintains documented procedures for continuous improvement, ensuring consistent compliance with international specifications. Third-party inspection services from SGS, BV, or TUV are available upon customer request.
Professional Packaging and Global Logistics
We protect each ANSI B16.5 Class 150 flange with anti-corrosive oil coating and individual wrapping before securing them in export-grade wooden crates or pallets. Clear labeling includes heat numbers, size ratings, material grades, and batch identifiers for complete traceability. Documentation packages contain commercial invoices, packing lists, certificates of origin, and material test reports. Our logistics network facilitates timely delivery to over 70 countries, with customized shipping solutions for urgent project requirements.
