Features

  • Premium 304/316 Stainless Steel Material: Available in standard 304 and 316 stainless steel grades. Delivers exceptional rust-proof, acid and alkali resistance, and oxidation stability, perfectly adapting to humid, corrosive and harsh industrial environments for prolonged service life.
  • Solid Integral Blocking Design: Full solid plate structure without pipe holes provides complete pipeline sealing and isolation. Effectively blocks pipe ends, isolates idle pipeline sections, and supports pipeline pressure testing and maintenance operations.
  • Precision CNC Machining: Adopts advanced CNC precision machining technology with flat and smooth sealing surfaces and accurately positioned bolt holes. Strict dimensional tolerances ensure perfect matching with standard pipe flanges for seamless assembly.
  • Superior Sealing & Isolating Performance: Uniform flat sealing surface fits tightly with various standard gaskets. Achieves excellent airtight and watertight isolation, effectively preventing medium leakage and ensuring safe pipeline isolation and shutdown.
  • Excellent Pressure & Impact Resistance: One-piece integral forging enhances overall structural rigidity and thickness. The blind board flange withstands ultra-high pipeline pressure and mechanical impact without deformation, cracking or leakage.
  • Simple Assembly & Disassembly: Universal standard size and bolt hole layout support fast on-site installation and removal. Simplifies temporary pipe blocking, equipment overhaul and pipeline reconstruction to save project time and labor costs.
  • Flexible Industrial Functions: Multi-functional pipe fitting supports permanent pipeline closure and temporary isolation, also serving as essential auxiliary equipment for pipeline pressure testing and safety inspection.
  • Wide Industrial Application: Widely used in chemical engineering, water treatment, oil and gas, power plants, pharmaceutical, municipal and petrochemical industries for pipe end sealing and system isolation.
  • Strict Factory Quality Inspection: Every stainless steel blind board flange undergoes strict pressure resistance testing, flatness inspection and dimensional calibration, complying with global industrial standards for stable and reliable quality.
  • Cost-Effective Factory Direct Supply: Professional stainless steel flange manufacturer direct sales without middlemen markup, supplying high-quality industrial blind flanges to reduce global buyers’ procurement budgets.
