Why Your Current Joint Flange Is Holding Back Production

  • High Price, Low ROI – Conventional metal flanges can cost up to $120 / unit, inflating project budgets.
  • Leakage & Maintenance Overheads – Rigid designs create stress concentrations, leading to 30‑40 % more downtime in high‑temperature lines.
  • Slow Delivery – Overseas suppliers average 6‑8 weeks lead time, jeopardizing just‑in‑time manufacturing.
  • Expensive Shipping & Customs – Heavy steel packages add 15‑20 % to landed cost.
  • Regulatory Uncertainty – Lack of CE, ISO, and RoHS certifications blocks EU procurement.
  • Limited Design Flexibility – Inability to customize joint angles or incorporate OEM branding.

According to the 2023 LSR market report, the global silicone component market is growing at **8.5 % CAGR**, yet many buyers still rely on outdated metal flanges that cannot keep pace with this growth.

Your Solution: Flexible Joint Flange from Guangdong Yingtai

Our flexible joint flange combines liquid silicone rubber (LSR) technology with precision‑engineered metal inserts to deliver a leak‑proof, vibration‑absorbing connection that meets **ISO 9001**, **CE**, **RoHS**, and **FDA** standards.

Core Advantages (1‑6)

  1. Ultra‑Low Leakage – LSR’s inherent elasticity creates a self‑sealing interface, reducing leak rates by 99.8 % versus conventional gaskets.
  2. Temperature Range – ‑50 °C to +250 °C – Suitable for cryogenic pipelines and high‑heat industrial furnaces.
  3. Rapid 48‑Hour Sample Delivery – OEM/ODM design ready within 2 days.
  4. Weight Reduction – Up to 45 % lighter than steel flanges, cutting shipping costs.
  5. Customizable Joint Angles (0‑90°) – Supports complex piping layouts without additional fittings.
  6. High‑Speed Production – 55 liquid‑silicone molding machines and 80 injection‑molding units enable 10,000 units/month capacity.
