What is Static equipment in Oil & Gas?

The majority of mechanical equipment found in oil and gas facilities belongs to the static equipment group, which comprises pressure vessels (drums, columns, reactors, filters) and heat exchangers (shell and tubes, plate and frame, air coolers). This article will contain cost-effective recommendations for design, materials, and fabrication. They aim to enable the inspector/surveyors/engineer/purchaser who is not an equipment specialist, to check that economical choices are made. The specification and selection of the equipment is the responsibility of the static equipment engineer, based on requirements specified by other disciplines, including process, materials and plant layout. Let’s start with the review of … Continue reading What is Static equipment in Oil & Gas?

What is Valve Trim

Valve Trim;  Valve Trim is a name for Valve ‘s Internal Parts that come into contact with Process Fluid and be Worn. The deterioration caused by the use of Valve Trim can be replaced (Replaceable), including Seat, Disc, Stem, Bushing, and others. The parts of Valve that are considered Valve Trim will depend on the type of Valves in the table. Meanwhile, the Body, Yoke, and Bonnet are not considered. Valve Trims Standard: (API 600)   Continue reading What is Valve Trim

API 650 / 653 – Tank Critical Zone

API 650 Storage Tank – Critical Zone in the Bottom;  API 653 Storage Tank Inspection, Repair, Alteration, and Reconstruction Code requires the tank bottom to be within 3 inches from the tank shell to be a critical zone because the area must support the weight of the tank shell that is placed near the welding line. Shell-to-Bottom makes Tank-Bottom in this area highly stressed. Critical Zone will have special requirements for inspections, repairs or reconstruction. Continue reading API 650 / 653 – Tank Critical Zone

API 650 – Storage tank Nameplate requirements

API 650 Storage Tank – Nameplates;  The Nameplate of the API 650 Aboveground Atmospheric Storage Tank as per Standard (para.10.1) specifies that the letters and numbers on the Nameplate must be at least 4 mm tall and the Nameplate must be welded or welded to the Tank Shell at the position near the Manhole or attached to the Reinforcing Plate of the Manhole. On the Nameplate, the Storage Tank must be specified as in the picture.   Continue reading API 650 – Storage tank Nameplate requirements

Allowable Stress in ASME VIII, B31.3, API 650, API 653

Basis of Allowable (Design) Stress in ASME VIII Pressure Vessel and ASME I Boiler;  (The Allowable Stress from SMTS and Allowable Stress) as well as the ASME B31.3 Proces Piping, for ASME VIII Pressure Vessel and ASME I Boiler values Allowable Tensile Stress of Material , the Code permits used to calculate the thickness and composition. The variables that are used to handle the pressure of the Pressure Vessel and Boiler will be specified in the ASME BPVC Section II Part D, which is generally equal to A value that is less than 1/3.5 Tensile Strength and 2/3 Yield Strength … Continue reading Allowable Stress in ASME VIII, B31.3, API 650, API 653
