What is Process Piping ?• Piping:
− Assembly of piping components used toconvey, distribute, mix, separate,discharge, meter, control, or stop fluidflows.
• Piping Systems:− Interconnected piping subject to the
same sets of design conditions.
5
What is Process Piping ?
• Process:− A series of activities performed in
particular ordered to convert rawmaterial into an useful product
• Process Piping is interconnectedpiping used in process industries toconvert raw material in to usefulproducts.
6
What is Process Piping ?• A Piping under the purview
of ASME Code - B31.3 is Process Piping
• A Process Piping Systems are design as per the guidelines given in ASME B31.3
7
ASME B31.3 Process Fluid Service
• Category D Fluid Service− The fluid is nonflammable, nontoxic, and not damaging to
human tissue.− The design pressure does not exceed 150 psig (1035 kPa).− The design temperature is between -29°C and 186°C.
• Category M Fluid Service− a fluid service in which the potential for personnel
exposure is judged to be significant and in which a singleexposure to a very small quantity of a toxic fluid, causedby leakage, can produce serious irreversible harm topersons on breathing or bodily contact, even when promptrestorative measures are taken
10
Types of ASME B31.3 Process Fluid
• High Pressure Fluid Service− High pressure fluids are those in which the Owner has
specified that the pressures will be in excess of thatallowed by the ASME B16.5 PN420 (Class 2500) rating forthe specified design temperature and material group.

Category M and High Pressure fluid service.− ASME B31.3 covers most of the process fluid in this
Category− Gauge

• Metallic gasket are made from forged ring or cut from the metal sheet and machined to achieve final surface finish and dimension
3
Dimension
• ASME B16.20-Metallic Gaskets for Pipe Flanges, Ring-Joint, Spiral Wound and Jacketed
• ASME B16.21-Nonmetallic Flat Gaskets for Pipe Flanges
4
Inspection and Testing
•Gasket Material shall be tested for−Hardness−Creep test−Thickness −Density −Compression −Recovery −Blowout resistance
5
Inspection and Testing •Following to be check for finished gasket
(Type test)−Tensile −Sealability−Flexibility −Corrosion resistance−Decomposition
6
Marking
• Manufacturer logo
• Manufacturing Code
• Size and Pressure Class
• Filler and winding material
• Inner and Outer ring material
7
Marking- Colour Code
• Spiral Wound Gasket are painted accordance with ASME B16.20.
• The solid colour on the centering ring indicates the metallic winding material
• The stripped colour indicates the non-metallic filler used between the metal winding.

Bolting
• Bolting is a term that includes stud, bolts, nuts, andwashers
• Also Known as fastener

Washers
• Conical or Belleville Springs washers−Keep bolted joints tight−High spring loads with small deflections−Used in area where vibration, differential thermal expansion,
and bolt creep present

Bolting Material
Wiki Common user: Alexander AlUS
Material of construction
• Carbon steel
• Low alloy steel
• Stainless steel
• Exotic material, such as Monel, Inconel, Nickel alloy
Material of construction
• These material further divide in −High Strength− Intermediate strength− Low Strength
• List of ASTM Material grade used for manufacturing stud are listed in ASME B16.5
Coating • Bolting are also coted with different materials to
improve its corrosion resistance and reducemaintenance− Chrome plated−Galvanized− Xylan coated− PTFE coated
What we have learned?
• Materials for Stud, Bolt, Nut &washers
• Different type of coating

Bolting Manufacturing
1
Manufacturing of Stud & Bolt
• Rolling / Forming−Most common method for threading on stud and bolt− Cylindrical bar placed between two die and bar are rolled in
between the die−Used for stud and threaded portion of bolt
Wiki Common user: Wizard1913
Manufacturing of Stud & Bolt
• Machining− Threads are cut by lathe machine on blank−Hexagonal head of nut are also machine chamfered
4
Manufacturing of Stud & Bolt
• Forging / Die punching− Blank bar are placed between die and force applied to
produced threads in blank−Head of bolt are also made by die punching− Forging can be done by Hot & Cold forging methods
Wiki Common user: Wizard1915
What we have learned?
• Manufacturing Methods
• Testing Requirements
• Types of Testing
• Visual & Dimension Inspection
• Product Marking
