Application Scenarios

Flanges and fittings for chemical process piping

Illustrative uses of pipe components, not records of completed customer projects. Suitability must be confirmed against the approved project specification.

    Flanges and fittings for chemical process piping

    01

    Overview

    Chemical process piping may connect vessels, pumps, branches and maintenance interfaces. Procurement must distinguish the service conditions of each line. This application guide supports an enquiry for components and does not represent a delivered chemical plant project.

    02

    Requirements

    Identify the medium and its concentration, operating and design conditions, cleaning conditions where relevant, and the approved material specification. The label stainless steel does not by itself confirm chemical compatibility. Any corrosion allowance, special alloy, lining or cleanliness requirement must come from the project specification.

    03

    Product selection

    List elbows, tees, reducers and flanges against the relevant line class. Confirm end dimensions and wall thickness on both sides of a reducer. For equipment connections, specify the mating flange standard, facing and dimensions. Provide drawings for non-standard interfaces and identify required inspection documents.

    04

    Products

    Relevant catalogue families: stainless steel elbows, tees, reducers and flanges, with material grades confirmed per enquiry. Do not substitute a material based only on similar appearance or nominal dimensions.

    05

    Preparing your RFQ

    A useful RFQ includes the line list or bill of materials, grades, dimensions, quantities, required test records and packing cleanliness. Any alternative material or dimension must be identified for the buyer's technical approval before order confirmation.
