Diamondoid coatings derived from petroleum

Anti-corrosion coatings from Sub-One Technology are made from nanometer-sized carbon-based materials found in petroleum and developed by Chevron Technology Ventures (CTV).

Sub-One’s InnerArmor product line is available with molecular diamondoid coatings. When used to coat internal metal surfaces of pipes and other equipment, In-nerArmor coatings with diamondoids can extend part life by delivering very high hardness, low coefficient of friction and strong protection against corrosion and wear. “Increased equipment durability is important to many industries where parts are continuously exposed to harsh environments,” explained Andrew Tudhope, CEO of Sub-One Technology. “Combining the diamondoids developed by CTV with the durability, rigidity and heat resistance made possible by the InnerArmor deposition process creates protective coatings that can extend part life, improve flow performance and significantly reduce operating costs.”

Lincoln Electric Introduces the SAE-300 MP Engine-Driven Welder

Pipe welding with an SAE-300 MP Engine-Driven Welder.
Pipe welding with an SAE-300 MP Engine-Driven Welder.

Field applications, such as pipeline construction or general construction require reliable, rugged equipment that stands up to rough conditions on the job site. The recently launched SAE-300 MP Pure DC Generator Welder, the latest engine-driven welder from Lincoln Electric, responds to these challenges, delivering consistent power and maximum control no matter how hot or cold, how long the pipeline or how tough the job.

This new engine-driven welder features Temperature Stabilization, which enables operators to “set it and forget it,” eliminating any need for adjustments based on ambient conditions or a warm-up period.

QuickPurge, High Speed Pipe Purging System

Waiting for pipe joints to be purged ready for welding can take anything up to four hours, depending on the diameter of the pipe being welding and the method chosen for purging. QuickPurge III cuts these waiting times so dramatically that they amortise themselves in less than one weld.

A 36” diameter stainless steel pipe for example can be purged down to 100 parts per million (ppm) of oxygen in under 32 minutes. Compare this with purging using foam dams that will outgas heavily into the weld zone and will take hours, not a few minutes.

Pipe bevelling tool ideal for large-diameter pipe that requires welding

The Terminator MILLHOG Pipe Beveling Tool is a portable pipe machining and welding end prep tool that includes a dual spring safety hanger for easily maneuvering and precisely aligning it into a large pipe I.D. The tool is designed for large pipe from 8-5/8-inch I.D. to 36-inch O.D. and can bevel, face, and bore simultaneously to produce end preps of any angle, including “j” preps.

It comes equipped with a dual spring safety hanger to help align the tool which rigidly clamps to the I.D., has a tracker to compensate for variations in wall thickness, and a precision feed control to advance into the pipe.

New features added to flow simulator

Version 1.7 of the LedaFlow transient multiphase flow simulator introduces major functionality changes including non-Newtonian fluids, wax appearance temperature, 3D visualization and flow line profile tools.

A number of important features have been added so users can perform a more complete analysis of the field to make better-informed decisions during design and operations. Among these is the ability for fluids to support Herschel-Bulkley rheology enabling non-Newtonian behaviour for simulations of operations such as well cleanup studies. Another functionality similar to hydrate formation margins is the wax appearance functionality allowing calculation of the temperature margin to wax formation.

Accuracy and ease of installation the benefits of Coriolis flow meters

Accurate measurement of liquids is important for all oil and gas industry production or consumption sites. This is especially true for bulk transfer devices where large volumes of products are being moved and must be monitored, including crude oil depots, gasoline and jet fuel tank farms, and refineries.

In the past, mass transfer was measured in batches with weigh scales or load cells. However installation, calibration, and maintenance of a scale or load cell are costly, difficult to do, time consuming, and don’t work for continuous processes. For these processes, such methods as orifice plates and magnetic flow tubes can measure volumetric flow, but additional instruments are needed to measure temperature and pressure to compensate for fluid density changes. Introducing additional instruments also introduces errors, which can result in an overall measurement error rate as high as three percent.

Proactive management for long term integrity of pipeline assets

Corrosion has always been a major threat to assets both on and offshore, yet it is often only as these assets age that the fight against corrosion becomes a priority to operators. To deliver enhanced long term integrity, operators must ensure that corrosion protection is an ongoing and proactive task, not a reactive one.

Over the last couple of decades, pipeline corrosion management has attracted ever-increasing attention due to a number of high-profile pipeline failures in the industry. Corrosion is an expensive business, and pipelines are increasingly subjected to attacks caused by transporting multiple products, empty periods during product changeover and below capacity flow through the pipelines. Pipeline failure can present a whole host of problems, from safety issues to the financial cost of total shutdown, which has highlighted the importance of risk assessment strategies and pipeline integrity management programmes.

Trelleborg Launches Mobile Production Unit for Flexible Coating Applications

Trelleborg’s offshore operation has launched its brand new Mobile Production Unit (MPU) – a portable coating facility that will enable onsite coating of thermal insulation, passive fire and corrosion protection, anywhere in the world.

The unit can be mobilized in a short time frame and sent straight to site to apply coatings such as Trelleborg’s thermal insulation – Vikotherm R2 and Firestop, a jetfire resistant material. This increases project flexibility and reduces the costs and lead times associated with transporting parts to a specialist coating facility.

Innovative Fasteners Increase Reliability and Rig Productivity

A unique internal thread form aids to resist shock, vibration, loosening and extreme temperature while enabling reusability.
A unique internal thread form aids to resist shock, vibration, loosening and extreme temperature while enabling reusability.

Downhole or topside, onshore or offshore, oil rigs have some of the most difficult operational requirements in the oil and gas industry.

Drilling deeper, farther, as well as both hotter and colder in increasingly remote locations has made oil rig reliability and serviceability even more vital. Today, their critical joints must be maintained and production downtime minimized, despite ever more extreme operational shock, vibration and temperature demands.

Experimental data enhances CO2 pipeline design

First-of-its-kind data relating to the depressurization of CO2 pipelines is being made freely available through industry cooperation. This will help fill knowledge gaps associated with the safe and reliable pipeline transport of CO2 and result in cost efficiencies through a significantly improved design basis for CO2 pipelines.

With energy security and climate change high on the international agenda, Carbon Capture Utilization and Storage (CCUS) is again gaining momentum. The DNV GL-led CO2- PIPETRANS joint industry project (JIP) that is now releasing new data focuses on the transportation component of CCUS projects.
