API Standards & Plant Integrity Guide
One complete engineering picture. Discover how key API standards interlock to build safe, reliable, and efficient process plants — and how NDT inspection methods and platform designers enforce compliance.
Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries
Design and performance requirements for centrifugal pumps used in critical refinery and process applications.
Minimum mechanical reliability, casing pressure containment, dynamic balancing, and vibration performance.
Axial and Centrifugal Compressors and Expander-compressors
Defines minimum requirements for axial and centrifugal compressors used in severe gas service.
Aero-thermodynamic efficiency, rotor stability analysis, dry gas sealing integration, and casing integrity.
Reciprocating Compressors for Petroleum, Chemical, and Gas Industry Services
Standard for design, operation, and maintenance of heavy-duty reciprocating compressor systems.
Pulsation control, cylinder thermal stress, rod load limits, and valve assembly reliability.
Rotary-Type Positive-Displacement Compressors
Requirements for dry and oil-flooded rotary positive displacement (screw) compressor systems.
Rotor profile mesh verification, thermal growth clearance, and continuous gas delivery stability.
Lubrication, Shaft-Sealing and Control-Oil Systems
Ensures reliable lubrication, shaft-sealing, and control oil supply for critical rotating equipment.
Dual redundant pump systems, oil reservoir filtration, thermal regulation, and emergency lube accumulator pressure.
Pumps & Gas Compressors Mechanical Shaft Seals
Standards for mechanical seals and dry gas seal support systems in hazardous hydrocarbon service.
Zero-emission containment, dry gas face separation clearance, seal flush piping plans (Plan 52/53/74).
Machinery Protection Systems
Covers continuous monitoring of shaft vibration, axial position, speed, phase reference, and bearing temperatures.
Hardware trip logic fault-tolerance, proximity probe calibration, and automatic trip protection against catastrophic failure.
Pressure Vessel Inspection Code: In-service Inspection, Rating, Repair, and Alteration
Covers inspection, repair, alteration, and re-rating of pressure vessels operating in process industries.
Remaining life assessment, minimum required thickness calculation, internal corrosion mapping, and weld integrity.
Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems
In-service inspection code for process piping circuits, elbows, injection points, and deadlegs.
Corrosion Under Insulation (CUI), localized erosion at elbows/tees, injection point decay, and fatigue cracking.
Risk-Based Inspection (RBI) Framework & Quantitative Methodology
Methodology to calculate risk profiles (PoF × CoF) to optimize inspection intervals and target critical damage mechanisms.
Probability of Failure (PoF), Consequence of Failure (CoF), damage mechanism modeling (thinning, SCC, HTHA, fatigue).
Sizing, Selection, Installation & Pressure-Relieving Systems in Refineries
Governs pressure relief valves (PRVs), rupture disks, flare headers, and emergency depressurization systems.
Overpressure scenario relief rates, acoustic fatigue in flare piping, valve seat tightness, and flare radiation.
