High Precision CNC Turned Flange End Cover for Gas-Liquid Separator Components

Product Overview

The High Precision CNC Turned Flange End Cover is a precision-engineered closure component specifically designed for gas-liquid separators, pressure vessels, and industrial tank systems. Manufactured through advanced CNC turning processes, this flange end cover provides reliable sealing, structural integrity, and dimensional consistency for demanding separation applications.

As a critical component in separator systems, the flange end cover serves as the access point for inspection, maintenance, and internal component replacement. Its precision-machined sealing surface ensures leak-proof operation under varying pressure and temperature conditions, while the robust stainless steel construction delivers long-term durability in corrosive industrial environments.

Key Features & Advantages

High Precision CNC Turning
- Manufactured on advanced CNC lathes and turning centers, achieving dimensional tolerances of ±0.01 mm to ±0.005 mm on critical features
- Single-setup machining ensures perfect concentricity between the flange face, sealing groove, and bore diameter
- Superior surface finish of Ra ≤ 1.6 μm on sealing surfaces, with Ra ≤ 0.8 μm available for demanding applications
- Consistent quality across production batches, eliminating variations common in manual machining
Premium Material Selection
- Standard options: Stainless Steel SS304 and SS316L, offering excellent corrosion resistance
- SS304: Suitable for general industrial applications with moderate corrosion requirements
- SS316L: Enhanced resistance to chlorides, acids, and corrosive media; ideal for marine, chemical, and pharmaceutical environments
- Additional materials available: SS316Ti, duplex stainless steel, Hastelloy®, Inconel®, and titanium for specialized applications
Reliable Sealing Performance
- Flange face machined to industry standards: ASME B16.5, DIN EN 1092-1, JIS B2220, or GB/T 9119 as specified
- Available sealing face types:
  - RF (Raised Face) - Standard for spiral wound and flat gaskets
  - FF (Flat Face) - For full-face gaskets and low-pressure applications
  - RTJ (Ring Type Joint) - For high-pressure, high-temperature services
- Precision-machined gasket groove ensures consistent compression and leak-proof operation
- Compatible with various sealing solutions: spiral wound gaskets, O-rings, flat gaskets, and metal ring gaskets
Structural Integrity
- Designed to withstand pressure ratings up to 40 bar or higher, depending on size and material
- Suitable for operating temperatures ranging from -40°C to +300°C, with material and seal selection determining the specific range
- Robust wall thickness design ensures resistance to deformation under thermal cycling and pressure fluctuations
