Dig the Deepest of Piping Fabrication

After we surfing on piping and fabrication system or installed pipe or anything that connect with piping or fabrication system, now it's the time that we Dig the Deepest of Piping Fabrication.

Hammer Weld. 

Hammer Weld

Method of manufacturing large pipe (usually NPS 20 or DN 500 and larger) by bending a plate into circular form, heating the overlapped edges to a welding temperature, and welding the longitudinal seam with a power hammer applied to the outside of the weld while the inner side is supported on an overhung anvil.

Hangers and Supports. 

Hangers and supports include elements which transfer the load from the pipe or structural attachment to the supporting structure or equipment. They include hanging-type fixtures such as hanger rods, spring hangers sway braces, counterweights, turnbuckles, struts, chains, guides, and anchors and bearing-type fixtures such as saddles, bases, rollers, brackets, and sliding supports.

Header. 

Header

A pipe or fitting to which a number of branch pipes are connected.

Heat-Affected Zone. 

head affected zone

That portion of the base metal which has not
been melted but whose mechanical properties or microstructure has been altered by the heat of welding or cutting.

Heat Fusion Joint. 

A joint made in thermoplastic piping by heating the parts sufficiently to permit fusion of the materials when the parts are pressed together.

Horizontal Fixed Position. 

In pipe welding, the position of a pipe joint in which the axis of the pipe is approximately horizontal and the pipe is not rotated during the operation.

Horizontal-Position Fillet Weld. 

horizontal position fillet weld

Welding is performed on the upper side of an approximately horizontal surface and against an approximately vertical surface. 

Horizontal-Position Groove Weld. 

horizontal position groove weld

The position of welding in which the weld axis lies in an approximately horizontal plane and the face of the weld lies in an approximately vertical plane. 

Horizontal Rolled Position. 

horizontal rolled position

The position of a pipe joint in which welding is performed in the flat position by rotating the pipe. 

Hot Bending. 

Bending of piping to a predetermined radius after heating to a suitably high temperature for hot working. On many pipe sizes, the pipe is firmly packed with sand to avoid wrinkling and excessive out-of-roundness.

Hot Taps. 

Branch piping connections made to operating pipelines, mains, or other facilities while they are in operation.

Hot Working. 

The plastic deformation of metal at such a temperature and rate that strain hardening does not occur. Extruding or swaging of chrome-moly piping at temperatures between 2000 and 1600 F (1093 and 871 C) would be considered hot-forming or hot-working operations.

Hydraulic Radius. 

The ratio of area of flowing fluid to the wetted perimeter.

so, what do you waiting for, just see the information of piping system next.
