Research shows that a check valve failure may have led to the destruction of a Crew Dragon spacecraft during testing. However, the root cause could have been a nitrogen tetroxide leak.

Axial flow valves are often used in High Integrity Pressure Protection Systems (HIPPS) and present peculiar design features to suit HIPPS requirements: short stroke, pressure balanced disc and low internal mass to allow the use of compact actuators with fast response times.

When choosing a valve, two critical things to consider are quality and safety. In a technical paper that was recently issued by family-run company AS-Schneider, the limelight is put on cryogenic valves and how these can be utilized for safe transport and storage. Standard valves contract and expand when exposed to extreme temperatures, cryogenic valves however –providing the right materials are chosen – can withstand pressure at cryogenic temperatures.

Chevron’s six newest liquefied natural gas (LNG) carriers feature stainless steel containment tanks specially designed to reduce boiloff during transport. As global exports of natural gas continue to rise at a recordsetting pace, the enhanced efficiency of Chevron’s new vessels will help the company remain competitive in an increasingly crowded market.

The Safety Assessment Federation (SAFed) represents the UK’s independent engineering inspection and certification industry, which plays a key role in maintaining high standards of safety within the workplace. New guidelines published by SAFed have been introduced surrounding safety valves and pressure relief valves.

The four offset butterfly valve from the manufacturer Quadax is used worldwide in solar thermal systems and offers important advantages in terms of reliability and cost efficiency.

In the past 20 or 30 years, the world is changing rapidly. A lot of new technologies have changed our lives. To illustrate how fast those changes happened, I would like to take two samples from China as my country has developed at a rapid pace in the new millennium.

Dr. Baumann, international consultant and former VP of Masoneilan and Fisher Controls, is a real expert when it comes to control valves. To date he has authored 140 publications, is credited with over a hundred patents and has written several books. Valve World is therefore delighted to report that his latest publication on control valves is now available via the ISA.

Working in a plant means having to make technically based decisions promptly, says Dow materials engineer Dr.-Ing. Evelyn Dayss

When running at full capacity, the Reggane Nord Project promises enough gas to meet over 10% of Spain’s demand. For Repsol and their partners, the project reaffirms a focus on oil-rich Algeria, where support from the government has aided investment. This is the first gas project to tap into in the southwest of Algeria’s reserves, and opportunities for expansion abound.
