Flanges and types of flanges

Flanges and types

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. Types of Flanges The most used flange types ...

When to Analysis Piping System

Piping System Analysis

One of the most difficult decisions plant personnel face is whether or not to analyze an existing or new piping system. It is often hard to assess the point at which a piping system should be field-routed or when a full analytic solution is required. Although there are no simple answers to these questions, here are some conditions under which ... Read More »

Piping Stress Types

Piping Stress Types

Piping code stress types With regard to stresses, there are three main types of stresses that a designer must check for: Primary stresses resulting from primary loads (sustained) From external loading Not self-limiting and cause distortion Limit these loads to prevent plastic deformation Examples of loads: Internal-pressure, Weight. Sustained stresses must be less than sustained allowable stresses. Related Courses in ... Read More »

Suggestions for Reducing Equipment Loading

piping design courses

Piping imposes loads on equipment nozzles. These loads may exceed the allowable given by the manufacturer or codes such as API 610.The following guidelines may be helpful in reducing these piping loads on nozzles connected to equipment. 1. If the dead loads exceed the allowable, Ensure the piping system is adequately supported Remove unneeded supports, they may be the cause ... Read More »

In-Line Pressure Balanced Expansion Joint

In-line pressure balanced expansion joint

When axial deflections exist, and anchoring is impractical for structural or economic reasons, such as high in the air or short straight pipe runs between two large vessels, the in-line pressure balanced expansion joint is a powerful solution to a difficult design problem. The principle of this type of unit is essentially the same as the pressure balanced elbow type, ... Read More »

Jacketed Piping

piping design questions

A jacketed pipe is a pipe protected by an insulating cover. Typically used for the transportation of hot steam or hot water, a jacketed pipe maintains the temperature of the material flowing through it. Often found in buildings and ships, jacketed pipes also can be found in very large-scale pipelines that carry oil in severely cold areas, such as the ... Read More »
