A boiler is, in general, any closed liquid-containing vessel to which heat is applied. It is also called steam generator as it transforms water into steam. Boilers generally consist of metal shells (or bodies), headers and tubes that form the container of the steam and water under pressure and, in certain types, of the furnace and passages for the hot gases. Some boilers have additional drums called superheaters.
Bolt tensioners are tools that are used to tighten large diameter bolts properly. Bolt tensioners are easy to use and also save time as they are quite efficient as well.
Most methods cause friction loss. One good way to overcome such problems would be to use hydraulic bolt tensioner to overcome the uneven uniformity of tension in bolts.
This is achieved by simultaneously using a number of tensioners to ensure that there is an even pull down of the components in the joint.
Leak testing is a process used to detect manufacturing defects which helps verify the integrity of products and improve consumer safety.
A main component of many leak testing methods is the concept of leak flow, which refers to the leakage of a gas or liquid from the product.
