Product Description

Industrial Flange Product Description
High-performance industrial flanges serve as critical connectors in fluid and gas transmission systems, engineered to deliver reliability, durability, and precision across diverse industrial demands.
ASTM Industrial Standard Stainless Steel 304 316L Blind Blank Flange Shirley
Product Advantages
Our flanges stand out with superior material integrity, utilizing premium-grade materials such as carbon steel, stainless steel, and alloy steel to ensure exceptional resistance to corrosion, high pressure (up to 2500#), and extreme temperatures (-50ºC to 600ºC). The precision-machined sealing surfaces (raised face, flat face, ring joint) guarantee leak-proof connections, minimizing operational risks. All flanges are manufactured in compliance with international standards (ANSI/ASME B16.5, DIN 2501, JIS B2220) for consistent dimensional accuracy and interchangeability. With a wide range of types-including weld neck, slip-on, blind, socket weld, and lap joint flanges-we meet both standard and custom requirements for versatile system integration.

Product Applications
These flanges are widely applied in key industries where secure and efficient fluid/gas transfer is critical:
  • Oil & Gas: Used in onshore/offshore pipelines, wellhead equipment, and refinery systems for high-pressure crude oil and natural gas transmission.
  • Chemical Processing: Ideal for corrosive environments, connecting reactors, storage tanks, and chemical transfer lines with resistance to acids, alkalis, and solvents.
  • Power Generation: Employed in thermal power plants, nuclear facilities, and renewable energy systems (e.g., biomass, solar) for steam, water, and fuel line connections.
  • Water Treatment: Ensures leak-free performance in water supply networks, wastewater treatment plants, and desalination systems.
  • Marine & Shipbuilding: Withstand saltwater corrosion in ship pipelines, offshore platforms, and marine engineering projects.

Product Inspection
To guarantee uncompromising quality, our flanges undergo rigorous multi-stage inspection processes:
  • Raw Material Testing: Chemical composition analysis (via spectrometers) and mechanical property testing (tensile, impact, hardness tests) for all incoming materials.
  • Dimensional Inspection: Precision measurement of diameter, thickness, bolt hole spacing, and flange face flatness using CNC coordinate measuring machines (CMM).
  • Pressure & Leakage Testing: Hydrostatic pressure testing at 1.5 times the working pressure and pneumatic testing to verify sealing performance.
  • Non-Destructive Testing (NDT): Ultrasonic Testing (UT) for internal defects, Radiographic Testing (RT) for weld quality, and Magnetic Particle Testing (MT) for surface cracks.
  • Final Certification: Each batch comes with inspection reports and material certificates (EN 10204 3.1/3.2) to meet international quality standards.
