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.
