What is monolithic isolation joint?
A monolithic isolation joint (MIJ) is a single-piece electrical isolation block that is widely used in pipeline systems to reduce corrosion by the methods of cathodic protection. Monolithic isolation joints are an integral part of the pipeline system and provide satisfactory long-term integrity.
What is isolation joint in pipeline?
Insulating joints (or isolating joints or isolation joints) provide electrical isolation and cathodic protection in pipeline, tanks and pumping station where petroleum, gas and water are carrier fluid.
What is pipe isolator?
Thermoplastic isolators (TPI) provide optimum support and eliminate pipe contact with the supporting steel. TPI is used as corrosion prevention between the steel pipe and steel pipe support.
What does an isolation joint do?
Isolation joints allow for anticipated differential horizontal and vertical movements between pavements and structures. Their purpose is to allow movement without damaging adjacent structures.
What is an insulating flange?
Insulating Flange (FIK) Insulating flanges are those flanges equipped with plastic pieces that insulate and prevent the flow of an electric current between two metal surfaces. Insulating flanges are used in cathodic protection systems to prevent electrolytic corrosion.
Where should my isolation valve be placed?
“If you find that your leak is coming from a tap or a toilet you may be able to isolate it using an isolation valve instead of turning the water off to your entire property, the isolation valve should look something like this and it’s usually located, directly under your toilet or directly under your tap.”
Is isolation joint the same as expansion joint?
While isolation joints are recommended both inside and out, expansion joints are designed primarily for outdoor situations where weather extremes can add to slab movement.
Do isolation valves restrict flow?
If you are running mains pressure system and the taps aren’t rate suitably (and you can get taps suitable only for gravity fed systems), closing the isolation valves does nothing. What it does do is restrict the flow, so when you open the taps fully the flow is less so you reduce splashback etc.
Where should I put my isolation valves?
What happens if you put an isolation valve on the wrong way?
The ball is held on the seating with a spring clip any weight of water the wrong end will push the ball off the seating and eventually out the end of the fitting, along with the little ball.
