EN 1092-1_TYPE 02 PRESSED LOOSE FLANGE

The EN 1092-1 Type 02 Flange is a Loose Plate Flange (often referred to as a lap joint flange or backing flange) designed to be used in conjunction with a mating collar or stub end (typically Type 32 pressed collar, Type 33 lapped pipe end, or Type 34 weld-neck collar).

Unlike fixed flanges, a Type 02 flange slides freely over the pipe before the collar is welded in place. Once installed, the loose flange sits behind the collar, holding the joint together when bolted down. This design allows 360-degree rotation during assembly, making bolt-hole alignment effortless—especially in confined spaces, large-diameter lines, or systems requiring frequent disassembly.

Key Features

• 360° Rotational Flexibility: Because the flange is not directly welded to the pipe, it can rotate freely to line up bolt holes effortlessly with matching equipment or opposing flanges.

• Cost-Effective Material Savings: The process fluid only contacts the inner pipe and collar. This allows the loose plate flange to be made from lower-cost carbon steel, even when the pipe and collar are made of expensive stainless steel or nickel alloys.

• Simplified Assembly & Alignment: Dramatically reduces installation labor and downtime, eliminating the need for precise alignment during pipe welding.

• Non-Wetted Design: Prolongs flange life in corrosive environments since the backing flange never directly contacts the internal system fluid or media.

• Standardized EN Compliance: Precision-engineered to European standard EN 1092-1, ensuring exact bolt circles, hole patterns, and pressure rating compatibility (typically PN 2.5 to PN 40).

Key Applications

• Corrosive & Chemical Processing Lines: Highly popular in stainless steel piping systems where using a carbon steel Type 02 backing flange provides substantial material cost savings.

• Low-to-Medium Pressure Systems: Widely used in HVAC, water treatment, paper & pulp, and food/beverage processing networks.

• Frequent Maintenance Outlets: Ideal for sections of piping, strainers, or equipment connections that require regular unbolting, cleaning, or dismantling.

• Confined Space Installations: Prefabricated pipe spools and tight site layouts where rotating fixed welded flanges into alignment is difficult or impossible.
