The inside of Piping System and Fabrication

When yesterday I can't posting because I have to take a rest even for a day. But now I'm ready to continue with the inside of Piping System and Fabrication. So, lets rock baby.....

Dew Point. 

dew point

The temperature at which the vapor condenses when it is cooled at constant pressure.

Dilatant Liquid. 

If the viscosity of a liquid increases as agitation is increased at constant temperature, the liquid is termed dilatant. Examples are clay slurries and candy compounds.

Discontinuity. 

A lack of continuity or cohesion; an interruption in the normal physical structure of material or a product.

Double Submerged Arc-Welded Pipe. 

double submerged arc welded pipe

Pipe having a longitudinal butt joint produced by at least two passes,

one of which is on the inside of the pipe. Coalescence is produced by heating with an electric arc or arcs between the bare metal electrode or electrodes and the work. The welding is shielded by a blanket of granular, fusible material on the work. Pressure is not used, and filler metal for the inside and outside welds is obtained from the electrode or electrodes.

Ductile Iron. 

A cast ferrous material in which the free graphite is in a spheroidal form rather than a fluke form. The desirable properties of ductile iron are achieved by means of chemistry and a ferritizing heat treatment of the castings.

now Piping & Fabrication will continue in the next post, thanks for visiting and good luck!
