Pipe drift is a measure of the roundness or eccentricity of the inside wall of a pipe. "API drift" refers to primary specifications set forth in API Specification 5CT (ISO 11960), "Specification for Casing and Tubing". "Alternate drift" refers to alternate drift specifications listed in API 5CT. "Special drift" refers to industry drift ...

They were originally developed to remove deposits which could obstruct or retard flow through a pipeline (Fig. 1). Today pigs are used during all phases in the life of a pipeline for many different reasons. Fig. 1 Cleaning pig in a pipeline Fig. 2 Classification of pipeline pigs.

Pigging can be used for almost any section of the transfer process between, for example, blending, storage or filling systems.
Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress is not exceeded under different loads such as sustained loads, operating loads, pressure testing loads, etc., as stipulated by the ASME B31, EN 13480, GOST 32388, RD 10-249 or any other ...
