4 most important mechanical isolation methods of process piping & equipment

Oil and gas plant with closed and locked valve shawing different isolation methods.

Positive isolation is the isolation of process piping, equipment, or vessels from hazardous materials such that it is impossible for the material to enter the work area. Positive isolation must remove all risk of accidental reconnection to the source of the hazard due to equipment failure or operator error. There are several methods of achieving positive isolation some of which are discussed below.

Case Study: High temperature DBB valves for steam injection – A common enhanced oil recovery method

5 important facts for a safe and transparent (remote) third-party inspection

Safe and transparent through your third-party inspection (remote inspection).

We are all facing many restrictions due to the pandemic. Therefore, we need to find ways to still provide the best possible support to our customers. One digital service that our customers can use is our third party inspections – better said remote inspections.
Our customers can use the remote visual inspection to check the valve quality before shipping.

High pressure valves up to 15,000 psi in offshore application

Offshore platform with high pressure valves up to 15,000 psi.

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.

Chloride induced stress corrosion cracking (CISCC) in pipelines

Chloride Corrosion of pipeline - Chloride induced stress corrosion cracking (CISCC).

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).

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We based the design on the standard SHELL MESC SPE 77/165 (which the MESC SPE 77/170 superseded) and EEMUA 182.

Why do material traceability and type 3.2 certification matter?

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.

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?”.
