Plant standards in the oil and gas industry

Factory standards in the oil and gas industry and comparison with tapas.

I have now been in the field for more than 25 years and support my customers exclusively in Germany. I have noticed that the measurement technology in the plants is carried out very differently. Just as there are endless variants of Tapas, there are also many different types of measurement technology. As a passionate Tapas connoisseur and with over 30 years of professional experience, I know both areas very well.

Close-coupled installation vs. conventional installation

Close-coupled installation versus conventional installation.

In times of budget cuts and lack of skilled workers, it is all the more important to use the right product solutions in your plant. In my current article I would like to explain the advantages of a close-coupled installation in the area of one of our products, “monoflanges”. That can have a very positive effect on your maintenance and operating work.

Chemical injection quill for oil & gas application

Chemical injection quill for oil and gas application.

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.

DBB system in instrument piping – a cost effective safety solution

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We based the design on the standard SHELL MESC SPE 77/165 (which the MESC SPE 77/170 superseded) and EEMUA 182.

Cryogenic valves for LNG application – Part 2

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?”.

Cryogenic valves for LNG application – Part 1

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.

All about Close Coupled Flush Ring

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.
