INTRODUCTION
Petrosin Ravi Industries Ltd., which was established
in 1965. Petrosin Ravi is locatedat Kala Shah Kaku,
Lahore. Compnay is engaged in fabrication and
manufecturing of pressure vessels.
FABRICATION:
Fabrication is the building of structures by cutting, bending, and assembling processes.
A system of pipes that compose a structure according to drawing is called Piping.
PIPING
MATERIAL COADS
ASTM A105
Standard Specification for Carbon Steel Forgings for Piping Applications.
ASTM A234
Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service
ASTM A106
Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service.
ASTM A516 Gr 70
Carbon Steel Plate for Boilers and Pressure Vessels
HEAT NUMBER
A heat number is an identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill.
Numerical Significance
2 6 490
Indicated furnace number
Indicated years of melted metals
Melt number
Welding joins metals by melting and fusing 1, the base metals being joined
and 2, the filler metal applied.

Chemical composition
Pipe is used to transport the fluid like water, oil or similar . The outside diameter
stays constant and the wall thickness increases with larger schedule number. Pipe
wall thickness is defined by the 'pipe schedule' and tube wall thickness is defined
by the 'Birmingham wire gauge' for tubes.
PIPE AND TUBE
Standards: ASME B36.10 ASME B36.19
Material: 106 Gr B
PIPE TUBE
SCHEDULE ASME B36.10
Specific pipe is identified by pipe diameter and another non-
dimensional number for wall thickness referred to as the Schedule.
FLANGE
Standards: ASME B16.5 or ASME B16.47 Material: A105N
Weld Neck Flange Blind Flange
Elbow: elbow is pipe fitting which is used as connection point between two lengths of pipe to produce change in the direction of flow in the pipe. Standard: ASME B16.25 Material: A234

RDUCER
A reducer is the component in a pipeline that reduces the pipe size from a larger to a smaller.
Standard: ASME (B16.9) Material: A 234
TEE
Pipe Tee is a type of pipe fitting which is T-shaped having two outlets, at 90° to the connection to the main line
Standard: ASME B16.9 Material: A234

VORTEX BREAKER
A vortex breaker is a device used in engineering to stop the
formation of a vortex when a fluid (liquid or gas) is drained
from a vessel.

SADDLE
3 PHASE SEPARATOR
A vessel that separates the well fluids into gas and two types of
liquids: oil and water due to their density difference.

NDT
Dye Penetrant Inspection:
Dye penetrant inspection is a widely applied and low-cost inspection
method used to locate surface-breaking defects in all non-
porous materials (metals, plastics, or ceramics).
NDT
Radio Graphic Test:
Radiographic Testing is a non destructive testing (NDT) method of inspecting
materials for hidden flaws by using the ability of short wavelength electromagnetic
radiation (high energy photons) to penetrate various materials.
NDT
Hydro Test:
Design Pressure: 1350 Psig Test Pressure: 1755 Psig Holding Time: 1 Hour
P W H T
Stress Relieving is done temperature below the critical range to
relieve the stresses resulting from cold working, shearing, or gas
cutting.
SAND BLASTING
Electrometers are used to measure dry film thickness.
ELECTROMETER:
An ultrasonic thickness gauge is a measuring instrument for
the non-destructive investigation of a material's thickness
using ultrasonic waves.
