Piping Material Specification: Flange Group (4 of 10)




Piping Material Specification is one of the most important deliverable from Piping Discipline. it becomes basis for so many other deliverables from various departments.

This document covers minimum requirements for various piping materials necessary for the design of the piping/ pipeline. The Piping Specification (abbreviated.. Pipe Spec) is a document prepared during the design phase of any project. It provides the appropriate selection, specification and material grade of pipe and piping components for a given service.

Piping Specifications define application design and construction rules and requirements for piping components as flanges, elbows, tees, valves etc. All Piping Material Class Specification must have a front cover with a written section containing the following:

  1. Document Title.
  2. Document Number along with Revision history.
  3. Name of Responsible person, checker, approver along with creation date.
  4. Contents in Tabular or properly arranged format.

This course is organized in such a way so that even the beginners can understand the basics and start implementing the knowledge in their live project. A lot of concepts & fundamentals are explained in such a way that it is very easy to digest & learn.

In any Piping system flanges are used as a connecting element to connect one Pipe to other Pipe, Pipe to Valves, Pipe to Pumps, Pipe to any equipment, Pipe to any specialty items. Basically, Flanges made up a linkage to make a pipework system.

Flanges are available in wide ranges of Types, Size, Material based on the applications.
