Things You Must Know When you do Piping Design

Be The First To Comment
Tubular products are termed ‘tube’ or ‘pipe’. Tube is customarily specified by its outside diameter and wall thickness, expressed either BWG (Birmingham wire guage) or in inches or in thousands. Pipe is customarily identified by ‘nominal pipe size’ with wall thickness defined by ‘schedule number’.


Piping materials

Carbon steel pipe is strong ,ductile, weldable, machineable, reasonably  durable and is nearly always cheaper than pipe made from other materials. If carbon steel pipe can meet the requirements of pressure, temperature, corrosion resistance and hygiene, it is the natural choice.

Material Selection – Common Specifications for Carbon Steel Systems

Be The First To Comment
As can be seen from the Table, material selection can be made from available national standards such as ASTM and API.

Important Definitions & Considerations in Piping

1 Comment
Creep: Time dependent deformation of material that occurs under load at Elevated temperatures. 
  • Creep range for Low Carbonsteel Material =0.05 to 0.25 
  • Creep range for Medium Carbonsteel Material = 0.25 to 0.5
  • Creep range for High Carbonsteel Material = >0.5
Jacking oil: In order to prevent the metal to metal contact b/w the journal & bearing shell during startup & shut down, which is damaging in the long term, an oil pocket is machined in to the bottom shell of the journal bearing is supplied with oil under high pressure.

Pipe Size & Material Selection

Be The First To Comment
Velocity of material which the pipes are holding.

                   Velocity of the gases and air =15 to 20 m/s
                   Velocity of steam                   = 40 m/s

Pressure drop should be minimized to get better efficiency of machine.

Generally we allow 1% of pressure drop in 100mt.length.

Pressure drop is inversely proportional to Dia. of the pipe.

Steel Pipe And Fittings

Be The First To Comment
The decision regarding where to apply the mortar lining for steel pipe — at the manufacturing plant or in the field — is based on a number of factors including manufacturer capabilities, pipe diameter, shipping and handling considerations, and field installation conditions. As with ductile iron pipe, steel pipe can be supplied
with a range of linings, only one of which is cement mortar lining.

Ductile Iron Pipe and Fittings

Be The First To Comment
In most cases, ductile iron pipe and fittings are mortar-lined at the factory. Field application of a mortar lining is normally done on older, in-service pipe for rehabilitation purposes. Ductile iron pipe can be supplied with protective linings other than cement mortar lining. Some of the other protective linings may be more appropriate, depending upon the fluid being transported. For instance, ductile iron pipe transmitting raw sewage under gravity flow conditions might be lined with a protective material since sulfuric acid, which may form in the space above the flow, can severely attack portland cement mortar linings and ferrous pipe materials. For most non-aggressive raw water and potable water transmission situations, cement mortar linings are very economical and the most common means of protection.
