EN 1092-1_02 LAP JOINT FLANGE (ISO TYPE DIN 2642)

The EN 1092-1 Type 02 Flange (commonly designated as a Loose Plate Flange or Lap Joint Flange) is a non-welded, movable flange component engineered for paired use with a mating collar or stub end (such as a Type 32 pressed collar, Type 33 lapped pipe end, or Type 34 weld-neck collar).

Unlike fixed flanges that are welded directly to the pipe wall, the Type 02 flange slips loosely over the pipe before the stub end or collar is butt-welded to the pipe extremity. The flange sits behind the lip of the collar, serving as a backing plate that transmits clamping pressure across the gasket when bolted to a mating flange. This loose configuration allows 360-degree rotation prior to bolt tightening, offering major installation advantages in complex or frequently serviced piping networks.

Key Features

• 360-Degree Rotational Freedom: Rotates freely around the pipe axis prior to bolting, making bolt-hole alignment effortless—even on long spools, off-axis connections, or cramped site layouts.
• Significant Cost Optimization: Because the backing flange never contacts the internal process fluid, it can be manufactured from cost-effective carbon steel, even when the pipe and wetted collar require expensive stainless steel, duplex, or nickel alloys.
• Non-Wetted Backing Design: Prevents media-induced chemical attack and internal corrosion on the main flange body, extending the mechanical lifespan of the bolting assembly.
• Simplified Assembly & Rapid Maintenance: Eliminates the need for precise rotational orientation during pipe welding, drastically reducing field fit-up labor, installation time, and maintenance downtime.
• Standardized EN 1092-1 Compliance: Fully compliant with European dimensional standards, ensuring exact bolt circle diameters, hole counts, and pressure class compatibility (typically PN 2.5 through PN 40).

Key Applications

• Corrosive & High-Alloy Piping Systems: Extensively applied in chemical processing, pulp and paper mills, and desalination plants where using stainless steel collars with carbon steel backing flanges yields major material savings.
• Frequent Maintenance & Inspection Outlets: Ideal for piping segments, inline strainers, valve connections, and equipment manifolds that require frequent unbolting, cleaning, or replacement.
• Pre-fabricated Pipe Spools: Used in offshore, shipbuilding, and modular plant construction where aligning fixed welded flanges across prefabricated sections can be challenging.
• Low-to-Medium Pressure Utilities: Suitable for water treatment, HVAC, industrial cooling loops, and low-pressure fluid transport lines.
