Types of Loads Considered for Piping Stress Analysis

Every Piping system is subjected to different loads during its design life which develops stresses in the system. Depending on the stress design basis the system is classified as stress critical or non- stress critical. All the stress critical system shall be stress analyzed using software system (eg.Caesar II) to keep the stresses within the allowable limits as per the ...

Anti-Surge Valve Piping for Gas Compressor

1. Introduction to Anti-Surge Valve: The anti-surge valve piping is the recycle loop that connects the discharge of the compressor (generally downstream of the discharge cooler) back to the suction side(generally upstream of the scrubber). This allows the compressor to flow through bypass and keeps the compressor from surging (reverse flow thru compressor). The anti-surge (control) valve is installed in this line. ...

Pressure Measuring Instruments: Selection & Application

1. Introduction Fluid pressure is defined as the measure of force per-unit-area exerted by a fluid, acting perpendicularly to any surface it contacts. Pressures and pressure measurements can be extremely complex and complicated. However, if the proper techniques are used, it is possible to obtain accurate pressure measurements. Selection of pressure instrument for a particular application must be done carefully, taking ...

Multiphase Flow Meter- Well Fluid Analysis Meter

1. Introduction to Multiphase flow meter (MPFM) A Multiphase flow meter in the Oil and Gas applications can measure the three phase flow (gas, Hydrocarbon liquid, water) without any so called separation by the process separators. The flow meters produce output flow rates for all the three components. The design and engineering of a MPFM is done with respect to ...

Restriction Orifice (RO) – Flow Control Instrument

1. Introduction to Restriction orifice (RO) Restriction orifice (RO) is mainly used to achieve controlled or restricted flow of process medium. The orifice offers a restriction to the process flow and the pressure head drops from the upstream to the downstream. The permanent pressure loss by the device is the intended pressure drop for which it is sized. The area ...

Compressor Shelters: Introduction, Layout, Types, Sizing

1. Introduction Piping Engineer will be responsible for layout and floor space occupied by the shelter based on input from compressor vendor. Mechanical (Rotating) Engineer will be responsible for determining height of shelter as well as the type and capacity (SWL) of the crane. Piping Engineer and Mechanical (Rotating) Engineer will provide respective inputs to Civil Engineer for structural design. ...

Clamp/Hub Connectors: Piping Connecting System

1. Introduction to Clamp/Hub Connectors Clamp/Hub Connector is a type of connection system which consists of three components, Hub, seal ring, clamp along with bolting. Applicable piping classes, sizes are generally considered as defined by the CLIENT specifications. Fig.1 shows the components of a clamp connector. The purpose of this post is to provide guidelines for design, material and inspection ...
