Rubber Hose
- Thread starter meca
- Start date
We use rubber hose in oil services that contain bitumen and naphtha. The spec we normally go for is a nitrile that is resistant to the naphtha. The temperatures are relatively low - less than 200 degrees F.
We use hose for wear resistance in addition to flexibility. Inspecting hose for wear is difficult, hard to measure with calipers the remaining wall. Most companies will now provide you with a wire buried spirally a certain depth into the rubber. Two ends of the wire stick out, and you can test the continuity. if there is no continuity, then you have worn out through the wire. You can also get colored layers that will indicate how far you have worn.
