Butt weld fittings is one of the most popular connection type in pipeline systems. It always been required in large quantities in different industries, and especially for the large diameter pipelines. What is Butt Weld FittingsButt weld is to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would allow to branch off, allow for change of direction of flow, attach auxiliary equipment, or reduce the size of the pipe. We aware the beveling is very important processes in the whole production procession of butt-welding pipe fittings, we always make beveling according to the standard … Continue reading Weld beveling for flange and fitting
The socket weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve, fitting, or flange. The joint construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations. Advantages of Socket Weld Pipe Fittings The socket weld pipe fittings can be used in place of threaded fittings, so the risk of leakage is much smaller. Socket weld pipe need not be beveled for weld preparation. The weld metal can not penetrate into the bore of the pipe. Construction costs are lower than with butt-welded joints due … Continue reading Why is the Gap needed on Socket Welds
The Knock out drum is a vessel in the flare header system designed to remove & accumulate condensed & entrained liquids from the relief gases. Both the horizontal & vertical design is a common consideration for the Knock out drum, … Continue reading What is Knockout drum?

Despite its inherent resistance to corrosion, stainless steel tubing installed in a marine environment suffers from different types of corrosion throughout its expected lifetime. Such corrosion can lead to fugitive emissions, lost product, and potential risks. Offshore platform owners and operators can reduce corrosion risks at the outset by specifying more robust tubing materials that offer better corrosion resistance. Later, they must remain vigilant in their inspections of chemical injection, hydraulic, and impulse lines, as well as process instrumentation and sensing equipment, to ensure corrosion isn’t threatening the integrity of the installed tubing and impacting safety. Localized corrosion can be … Continue reading What is PREN value for pitting corrosion?
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
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?
