Learn About Different Types of Pipe Supports

Be The First To Comment
Find about different types of pipe supports being used while one design pipe routing for any system and for ensuring smooth working of it.

Broadly Pipe Supports are classified in three Categories:

1. General Details

  • Primary Supports
  • Secondary Supports

2. Construction Details


3. Functional Purpose

  • Loose Support
  • Longitudinal guide
  • Transverse guide
  • Fixed Point – Non welded Type
  • Anchor – Welded Type
  • Limit Stop
  • Special Support

Type of Piping Systems in Piping Design

Be The First To Comment
Find out major types of Piping Systems being implemented in Piping Design:

Based on Design Temperature and Pressure

  • Critical
  • Main steam piping, HP Bypass system
  • Hot Reheat System, Cold Reheat System and Low Pressure (LP)
  • Bypass System
  • Boiler Feed Water piping
  • Turbine Extraction system
  • Steam piping to Turbo driven Boiler Feed Water pump.
  • Condensate piping
  • Auxiliary steam piping.
  • Any system with a design temperature of 400 deg C or higher.
  • Any system with an ASME flange rating of Class 900 or higher
  • Other systems which are considered critical because of pressure
  • and/or Temperature Considerations.
  • Non Critical
  • Exclusive of all above

Need of Pipe Supports and Hangers in Piping Design

2 Comments

INTRODUCTION

The Piping Profile in general can be considered as a complex and rigid piping network consisting of various piping components, which have different diameters and weights. At the same time the above network is also subjected to temperature change while switching from installed to operating condition (and visa versa) resulting into its thermal growth in various directions in proportion to the length of pipes. The structural integrity of the above network must therefore take into account the overall weight effect of the profile besides its thermal growth.

A satisfactory design of the Piping System should therefore give a careful consideration to achieve the above requirement. This is generally accomplished by providing external attachments (known as pipe supports) at various locations of the piping profile. This document deals with the basic purpose of the pipe supports, classification based on construction / functions and a few typical types of pipe supports. In general it deals with metallic piping systems only.

How to Position Radial Nozzles

Be The First To Comment
Positioning Radial Nozzles

Method 1

1. Create and then position the nozzle to the correct Up coordinate only. P1 should point in the correct direction, i.e. E 45 N.

2. From the application menu bar, choose:
Position > Move > Distance
The direction of movement is the same as P1. The distance is the PROJECTION DISTANCE. Note: If the nozzle’s height is set from face to centerline, you might use

Pressure Tubing Role in Piping Design

Be The First To Comment
Pressure pipe and tube products are manufactured to a variety of standard specifications of varying designs, employing different manufacturing practices and using a wide variety of materials. The end user of these products must apply the leastcost product suitable for the specified service conditions. Typically, steel and alloy pressure piping is available in cast, wrought, and seam-welded forms. Welded and seamless wrought steel pipe is supplied in standard sizes and wall thickness conforming to ASME B36.10M. Stainless-steel pipe is supplied in standard sizes and wall thickness conforming to ASME B36.19M.
