We all know, pressure is one of the most important process parameters, in the field of measurement and control. Pressure measurement under extreme applications are done for enormously high-pressure range. These measurements must be safe and precise, for which we need reliable valves to maintain tight control and regulation at these high pressures.Continue reading
To support users in their proper planning and technical evaluation, I would like to share some information about one less-familiar product in the industry, the chemical injection quill.Continue reading
The energy sector has passed through various atmospheric and process environmental challenges. How big is the challenge? It depends on the region, application, process media, and industry. It is also not limited to these factors. One of these challenges is Chloride Induced Stress Corrosion Cracking (CISCC).Continue reading
I remember very well when we started the development of our Double Block & Bleed Valve Series. We called it “VariAS-Blocks”. Production started 20 years ago, and we have made many improvements since there.
We based the design on the standard SHELL MESC SPE 77/165 (which the MESC SPE 77/170 superseded) and EEMUA 182.Continue reading
Today, manufacturing has become global. Imagine a salesman in Europe or America. He supplies his product for a project in the Middle East, coming from their factory in India, which sources its raw material from China or other parts of the world. It has support and customer service from Southeast Asia. This scenario is common in companies with operations across the globe.Continue reading
In our second part of the cryogenic valve series I would like to responsive on questions like “What are the challenges of using cryogenic?”, “Selecting a valve for cryogenic service.”, “How can engineers ensure tightness of cryogenic valves?” and “What should engineers pay attention to during assembly of cryogenic valves?”.Continue reading
One of our customers needed a primary isolation valve for a pressure measurement on a container ship. The ship uses natural gas power. The valve had to meet the Fire Safe API requirements. It also had to pass a cryogenic test with liquid nitrogen (-196 ° C). The container ship rides under the American flag. Thus, an independent examiner had to administer the test. This examiner came from the American Bureau of Shipping (ABS) and the US Coast Guard.Continue reading
The chemical industry uses flush rings for diaphragm seals. These rings prevent clogging of the instrument connection. The technician mounts the ring between the process flange and the diaphragm seal. It has flushing ports and membranes. The flushing ports allow users to wash out particles from in front of the membrane. It also has a pressure chamber, which users can vent, drain, or fill with cleaning liquid. The user can then flush the chamber.Continue reading
In plant construction, you often come up against challenges where standard valves no longer fit. Then, you need professional support who can advice you what to do when standard solutions don`t meet the requirements of the installation.
Some time ago we have created a simple but very helpful solution for a pressure gauge manufacturer. The solution refers to the alignment of the pressure gauge display.Continue reading
Whether in Alaska, Norway or Russia: Industrial valves, such as those used in chemical plants or the oil industry, are exposed to extreme cold as low as -55°C in some regions. However, not all industrial valves are suitable for operation in extreme cold. Three criteria are decisive.Continue reading
