De
sig
n Various National and International codes like ASME B31.4, API 1104, API 1102, API 5L,
Petroleum Rules 2002, OISD 141, 117, 214
Corrosion Allowance of 0.5 MM
Safety Factor of 0.72 as per ASME B31.4
Str
ength
Selection of line pipe based on API 5L standard spec
Automatic / Semi-Automatic welding ensuring strength of weld area greater than parent material
100% Radiography is ensured for the weld joints as per API 1104
Pipeline is shop floor tested at 95% of SMYS
Pipeline is site tested at either 1.25 times the design pressure or 95% of SMYS
Concrete coating of Pipes as anti-buoyancy measure
Sa
fety
The pipeline routes are selected based on urbanization and population
Laid at the minimum depth of 1.2 Meters
Environmental Impact assessment (EIA) and Quantitative risk analysis (QRA) studies
Higher wall thickness in Highway and Rail Crossings with casings ref. API 1102
Pipeline Laid 2 Meters below the Scour Depth using HDD while crossing Perennial rivers
Adequate safety margins considered for withstanding longitudinal stresses because of earthquakes / Tectonic Plate Movement
Mobile Cold Flare Systems for LPG Pipelines at Remote SVs

Corrosion Protection
Process Control
Safety/Security
Emergency preparedness
Internal corrosion:
� Dosing by Corrosion Inhibitor� Online Corrosion
Monitoring using Corrosion Probes
External corrosion:
� Anti corrosive coating using Denso/ 3 LPE coating.
� Corrosion protection thru Impressed Current Cathodic Protection
system
� PLC based onsite
control of various process and equipment parameters
� OFC Based dedicated telecommunication system for effective and
quick communication between stations.
� SCADA based control
of entire pipeline for control of Process and equipment
� Dynamic and Steady state leak detection system based on
mathematical model of Pressure, temperature, volume and flow.
� Day and Night Patrolling of Line walkers
� CCTV Cameras in all stations and SV stations
� Security Tracking System to monitor the movement of line
walkers on a daily basis
� Pipeline Intrusion
Detection System to detect third party intrusion on our
pipeline ROU
� Offsite and On Site mock drill
� Village awareness and
Village coordination meet
� Security Coordination
