Flanges and types of flanges

A flange is a projecting flat rim, or a raised circle formed around the junction areas where two pipe sections, a pipe and a valve or pump, or a pipe and equipment join. flanges definition usually made from metal material like steel or stainless steel and are normally screwed or somehow bonded to the mating surfaces. Flanges can be categorized into several classes in that every class has distinctive characteristics and functions. Some common types of flanges include: Slide-on flanges: These are flanges in which the bore is slightly larger than the pipe bore to make the pipe fit into the flange and then use fillet welds. Weld neck flanges: These flanges have a formation of a neck that emanates from the base of the flange uses and soldered to the joining pipe. This affords additional reinforcement to the joint. Blind flanges: These flanges have no bore and are employed to block up the end of a pipe work or piece of equipment. Lap joint flanges: These flanges are in fact similar to the slip-on flanges but comes with a radius in the both ends of the flange face for the lap stub end. Threaded flanges: These flanges have internal screw threads by means of which a flange can be screwed on to a pipe. Socket weld flanges: These flanges are the same as slip-on flanges, however their inside diameter of the flange is slightly less than the diameter of the pipe. The pipe passes through the flange and fillet welded to make the connection. Spectacle flanges: These flanges are constructed from two disks of a metals where one of the disk is solid and the other one has a central aperture to create a “spectacle” when two disks are fastened together using bolts. Few of these structures are mainly used to have a distance between isolated structures or to maintain a structure for a certain period. These types of flanges types in different situations as per the requirements of the application. the suitable type of flanges has to be selected for the actual application and the flanges must be effectively installed and maintained for the sake of the piping system safety together with stability.

History of Ultrasonics

Ultrasonics, or ultrasonic testing or ultrasonic inspection, is one of the Non-destructive testing technique that identifies the defects in the material by the use of high frequency sound waves. To better understand the history of ultrasonography, one has to go as far back as the early part of the twentieth century.

Post Weld Heat Treatment

Post Weld Heat Treatment (PWHT) is a process where the welded portion of a metal structure or a member is exposed to a predetermined temperature and afterwards maintained at that temperature for a certain time. PWHT is aimed at reducing stress and strains, as generated during welding, while at the same time making metallurgical alterations that enhance the mechanical characteristics and toughness of the weld zone

ASTM Materials

ASTM materials as applicable and necessary to specify in the context of acoustical.Materials are those which satisfy the standard and specification of ASTM international this used to be known as the american society of testing and materials. These materials find application in several industries and the fact that they are tested and meet the ASTM standards is a plus for both buyer and seller. ASTM materials basically work with metals, plastics, ceramics, composites and much more. These standards are useful in areas like construction, engineering, production, aerospace as well as material science to name but a few because they help to determine compliance of products and materials with certain specifications in terms of their performance, safety and life expectancy.
