Product Description

Shaanxi Flourish Industrial Co., Ltd. is a 12-year professional manufacturer of industrial flange insulation gaskets and construction scaffolding supporting accessories, owning a 30,000㎡ intelligent production workshop. Our custom flange insulation gaskets outperform ordinary sealing gaskets widely sold on the market, adopting anti-corrosion EPDM/PVC/PTFE composite insulating substrates to realize four core values: high-voltage electric isolation, flange joint leak-proof sealing, pressure buffer protection and heat insulation. Compatible with standard steel pipe flanges, pipeline flanges and equipment connection flanges across petroleum, chemical, power and construction industries, we support full-size OEM customization with a daily output of 100,000 pieces. We provide one-stop supporting supply matched with scaffolding and pipeline accessories plus complete foreign trade service, greatly cutting overall procurement and operation maintenance costs for global contractors and industrial clients in the Middle East, Southeast Asia and Europe.


1. Product Overview: Industrial Flange Insulation Gasket


Flange Insulation Gasket is an indispensable insulating & sealing component for all types of metal flange connection systems, specially developed to solve hidden dangers brought by metal-to-metal contact between steel flanges. It is installed between two metal flange surfaces to fill assembly gaps and isolate conductive metal contact, fundamentally eliminating two critical industrial pain points:
  1. Galvanic corrosion and stray current damage to pipeline & equipment caused by direct metal conduction between dissimilar steel flanges;
  2. Medium leakage at flange joints, leading to fluid loss, equipment failure and frequent maintenance downtime.
With excellent elastic compression resistance, the gasket absorbs vibration and pressure impact during pipeline operation to protect flange surfaces from scratch and deformation, extending the whole pipeline system service life. Its stable heat insulation property also reduces medium heat loss, widely applicable to oil & gas pipelines, chemical fluid conveying pipes, power station equipment, factory hydraulic pipelines and construction industrial piping systems.

2. 4 Core Product Advantages

2.1 Superior High-Voltage Insulation, Prevent Galvanic Corrosion

Made of high-dielectric insulating substrate with breakdown voltage ≥15kV, the gasket completely cuts off conductive loops between different metal flanges, effectively avoiding electrolytic corrosion and stray current damage to pipelines, valves and industrial equipment. It complies with international petroleum, chemical and power industry safety standards, a mandatory matching part for long-distance transmission pipelines and chemical factory projects.

2.2 High-Elastic Compression Sealing, Zero Medium Leakage

Integrated molded with anti-leakage concentric sealing lines, the gasket closely fits uneven flange surfaces under bolt compression, no shrinkage, cracking or medium penetration under high fluid pressure. Compared with ordinary flat rubber gaskets, it achieves permanent tight sealing, drastically reducing manual maintenance and fluid loss costs for industrial operation.

2.3 Outstanding Weather & Chemical Resistance for Complex Working Conditions

Three mainstream substrate formulas to match different industrial media and temperature environments:
  • EPDM rubber flange gasket: Resists weak acid, alkali and water medium, works stably at -40℃ ~ 120℃, ideal for construction water supply & drainage pipelines, low-pressure general industrial piping;
  • Hard PVC flange gasket: Top-level insulation performance, strong compression and wear resistance, suitable for power plant equipment, medium-pressure chemical pipelines;
  • PTFE composite flange gasket: Resists strong acid, strong alkali, organic solvent and extreme temperature (-60℃ ~ 260℃), perfect for oil & gas transmission, high-corrosion chemical production lines.
All materials maintain stable insulation & sealing performance for long-term continuous operation, without frequent replacement.

2.4 Universal Flange Matching & Flexible Custom OEM

Standard sizes fit ANSI, DIN, GB, JIS all international standard pipe flanges, covering 1/2" to 48" nominal diameters. Custom thickness (2mm–15mm), inner/outer diameter and special shape are available. We adjust raw material formulas according to clients’ medium, pressure and temperature working conditions, and support OEM brand logo printing for bulk orders.
