Corrosion Under Insulation (CUI) – Mitigation methods
DNV GL unveiled a methodology for managing safety and cost associated with corrosion under insulation (CUI) alongside new technology designed to support it. CUI occurs when water becomes trapped between insulation and the piping and vessels it is designed to … Continue reading Corrosion Under Insulation (CUI) – Mitigation methods
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 different between Partly mechanized and Fully mechanized welding process?
Welding fabrication involves several operations which might have a significant ergonomic impact.This article aimed at providing an overview on these typical activities, and the most confusion on terminology of Partly Mechanized and Fully Mechanized processes during identify the welding personnel as a WELDER or WELDING OPERATOR? The role of welding personnel in welding processes: Based on the level of automation, processes are defined by applicable industrial standards as:– Manual processes, involving welders;– Partly mechanized (or semiautomatic) processes, involving welders;– Fully mechanized (or automatic) processes, involving welding operators;– Automatic and/or robotized processes, involving welding programmers, operators.Depending on the industrial needs, some … Continue reading What is different between Partly mechanized and Fully mechanized welding process?
What is water standards for hydrostatic testing?
Selection and Treatment of Water and Conduct of the Test, to Maintain the integrity of the System is a priority concern in new-building or construction project. Specially on Stainless-steel which is very sensitive to corrosion. 1.0 Introduction Welded fabrications are frequently tested hydrotested for pressure tightness. Unless properly conducted, this procedure can induce problems. It is important to avoid initiating corrosion of the fabrication by subjecting it to critical conditions outside the initial design constraints. Where the vessel is to handle materials which are later ingested, contamination must be avoided. Damage may be caused by the induction of latent corrosion … Continue reading What is water standards for hydrostatic testing?

What is Hot Induction Bends and Inspection guides.
This article outlines the minimum requirements for manufacturing of induction pipe bending according to ASME B31.8, ASME 16.49 and ISO 15590-1. Induction Bending is formed by passing pipe through an induction bending machine. This machine uses an induction coil to heat a narrow band of the pipe material. As the pipe is pushed through the machine, a bend with the desired radius of curvature is produced. The heated material just beyond the induction coil is quenched with a water spray on the outside surface of the pipe. Thermal expansion of the narrowly heated section of pipe is restrained due to … Continue reading What is Hot Induction Bends and Inspection guides.
