To understand the term ‘allowable leakage rate’ and demonstrates its empirical nature, it is beneficial to presents a brief and timely analysis of the international standard ISO 5208 for valve pressure testing. For this purpose, it is also important to analyze the refinement provided by the API 6D valve specification to the ‘allowable leakage rate’ values of ISO 5208. This in turn highlights the importance of a comprehensive assessment of the valve’s life cycle to achieve the best performance beyond the testing stage.

To meet the net zero targets and the contribution from hydrogen, valve sales will likely average $4 billion per year, over the next 10 years, and $6.3 billion over the next 30 years.(1) This includes the valves needed for hydrogen use, production, transport, storage as well as for carbon capture and sequestration.

The Houston Port region’s make up is so unique that there is no blueprint out there showing how to improve its economic development activities/assets, transportation infrastructure, workforce development entities, and investment protections. For this reason, Economic Alliance has established itself as the convening entity in identifying, prioritizing, and promoting issues of Houston Port region significance.

With the increased focus on environmental issues, energy producers are giving thoughtful consideration to the growing concerns of fugitive emissions, and all eyes are on a major player: valves. The world’s largest energy companies are now beginning to audit their greenhouse gas emissions, as well as other energy metrics, in order to achieve global sustainability initiatives such as, ‘Net-Zero 2050’.

Applying the correct bolt torque in a bolted flange joint assembly procedure to achieve a leak-free connection can be a complex endeavor. There are a myriad of variables that need to considered and controlled to be successful. By Isadora R. Henriques, Mechanical Engineer – Teadit

Hydrogen is expected to play a significant part in the low-carbon future that lays ahead. When interacting with the production and handling of any fluid, valves are not only necessary but critical to successful operations. A valve design in a hydrogen application requires two types of materials; metallic materials when dealing with high pressure and cryogenic temperatures, and non-metallic materials for overall static and dynamic sealing and seating. Hydrogen however, poses a unique challenge for the materials selection for valves. Due to its small size, hydrogen can diffuse into metallic and non-metallic components and, once there, can interact in deleterious, and not-yet-understood, ways with the material’s internal structure. Read on to learn more about hydrogen and its related damage mechanisms in common valve materials.

Pipelines are vital in production, distribution, and refining processes, as they deliver energy to various operations where it is turned into useful fuels and products for supply to local communities. There are many products commonly delivered by pipelines, including: crude oil, refined products (such as gasoline and diesel), and natural gas liquids (such as ethane and propane).

As many companies and producers of energy are looking toward establishing a cleaner future, a great amount of consideration is being put into the environmental impact of various fuels. As oil and gas will continue to be used in many industries for the foreseeable future, liquid natural gas (LNG), has become used more frequently, especially in various aerospace applications

When assembling bolted flange joints, reliability engineers, industry experts, gasket manufacturers, and almost anyone with ‘skin in the game’ agree that utilizing best practices is paramount to overall joint integrity, reliability, and most importantly, safety. A great deal of time and resources have been devoted to identifying those best practices and to training plant maintenance personnel and contractors on proper flange bolt-up.
