Backing Ring, Ball Joint, Base Metal, Bell Welded Pipe, Bevel Angle, etc (General Definitions)

Comes with General Definition from letter B, now I will write about Backing Ring, Ball Joint, Base Metal, Bell Welded Pipe, Bevel, Bevel Angle, Blank Flange, Blind Flange and Bond. and here it is :

Backing Ring. 

Backing Ring

Backing in the form of a ring that can be used in the welding of piping to prevent weld spatter from entering a pipe
and to ensure full penetration of the weld to the inside of the pipe wall.

Ball Joint. 

Ball Joint

A component which permits universal rotational movement in a piping system.

Base Metal. 

The metal to be welded, brazed, soldered, or cut. It is also referred to as parent metal.

Bell-Welded Pipe. 

Furnace-welded pipe produced in individual lengths from cutlength skelp, having its longitudinal butt joint forge-welded by the mechanical pressure developed in drawing the furnace-heating skelp through a cone-shaped die (commonly known as a welding bell), which serves as a combined forming and welding die.

Bevel. 

A type of edge or end preparation.

Bevel Angle. 

Bevel Angle

The angle formed between the prepared edge of a member and a plane perpendicular to the surface of the member.

Blank Flange. 

A flange that is not drilled but is otherwise complete.

Blind Flange. 

A flange used to close the end of a pipe. It produces a blind end which is also known as a dead end.

Bond. 

Bond

The junction of the weld metal and the base metal, or the junction of the base metal parts when weld metal is not present.

Just Keep following another post of Piping & Fabrication, because this will continue until of the end of this hand book.
