Applications

Diameter TransitionsEquipment InterfacesPipeline Packages

Installation position: At main-to-branch connections, diameter transition sections, water plant outlets and trunk-to-branch locations.
Purpose: Connects pipes of two different diameters.
Problem solved: Provides a smooth transition from larger trunk pipes to smaller branches and reduces hydraulic impact.

Selection and procurement checks

Confirm large-end and small-end dimensions, concentric or eccentric form, and installation orientation. For pump or equipment connections, check length, wall thickness and end forms against the interface drawing. Two nominal diameters alone do not define the complete requirement.

Information required for quotation

  • Large and small end diameters, wall thickness and length
  • Concentric or eccentric form and installation orientation
  • Material, connection form and equipment interface drawing

The materials and standards listed on this page identify reference procurement options. They do not imply that different grades, standards or product forms are interchangeable. Specify the governing standard, material grade, dimensions and inspection requirements in your purchase list; the agreed technical documents define the supply scope.

Include the quantity for each size, delivery destination, required arrival date, and any packaging, marking or documentation requirements so that the supply scope and delivery arrangements can be checked item by item.

Quality and inspection documents

Please state whether the order requires a Mill Test Certificate (MTC/MTR), an EN 10204 type 3.1 inspection certificate, heat or batch traceability, or other inspection records. The document type, applicable material and availability must be confirmed for the specific order. EN 10204 type 3.2 involves additional independent inspection requirements and must be agreed separately before supply.
