Hey guys, Has anyone had experience with Perma-liner or similar trenchless CIPP (cured in place pipe) repair? We have a manufacturing plant with sewer piping in bad shape due to chemical attack. I thought this might be a good option...

Thank you. I agree that about 140F and above should be covered, but I couldn't find anything that says it directly. I was hoping to find something to present to help my case when I make the suggestion to insulate a good amount of uninsulated steam piping that is within reach in production areas...

Hello, I'm trying to locate the current OSHA regulation for protecting workers from hot steam piping i.e. height for required insulation, distance required from walkways, etc. It's in a food manufacturing environment. I did a Google search and tried searching on OSHA's site but found only...

Hey guys We had this screw drive shaft break at the welds today. It was installed less than a year ago and I’d estimate only 1500 hours on it. Just curious what you guys think on the failure. The drawings do state the plate can be welded to the shaft to develop full strength. I wonder if...

We are asking them for help but so far Hoxton seems to know more than anyone we've talked to. We are using OEM plug We did figure out the spark plug testing procedure above - so we are clear on that now

Hey Hoxton It is Digester gas with human waste as the feedstock We do have a gas analyzer in place and have checked that in the past - we will get the latest copy of that TR and check it again though. I'm pretty sure we are OK there. We also scrub our gas and check regularly for H2S and...

Dgallup - There is a single coil for each cylinder. 12 cylinders total on this engine. They are not connected

Hey guys A little over a year ago we made post on here on looking for aftermarket pre-chamber plugs since we are going through a lot of plugs on our biogas engines - we were trying to save some money. At the time we decided to stick with the OEM plugs and have been continuing to use them to...

Hey guys, We have (3) MWM biogas engines at our plant all with same issue. Failing rubber parts in the glycol system. It’s closed loop about 40PSI 180F propylene glycol 40% mixed with deionized water Engines are about 5 years old with 24,000hours. This problem is costing a large amount of...

We are the owners and it was our employees who where negligent unfortunately. They are used pieces that are being repurposed. It sounds like we should replace the members. Thanks guys

Conveyor support diagonal members got bent from careless lifting. Anyone know enough to recommend should we replace the members or can we use as-is? https://files.engineering.com/getfile.aspx?folder=19077638-773c-488d-9e0a-25aaed3de444&file=5B91F195-BDE0-4D90-A9ED-D667BA5168A4.jpeg

Thanks. We had plan 11 on the first pump (Dean pump). The second MP HTO 120 pump - I am not sure - I just know it was recommended to us by one of our pump suppliers we trust and from the literature it seamed to be proper for the application. The plan 52 design looks expensive and seems a bit...

Closed cup flash point per Paratherm website >410F. MP Pump HTO 120 max operating temp = 650F per pump specs. Our actual fluid temp in the system is 350-375F

I have been told that too to some degree - but it happens that both pump manufacturers seem to think that the seals should not leak at all.

we did not take the pumps apart - one was done at the pump supplier, and the other was done at the pump manufacturer with John Crane rep present

When talking about the leak it is not pouring out - about 2 tablespoons per day leak if I had to guess. Not really trying to figure this out online - just hoping to get a couple names so we can consider someone to hire

Thanks guys. Both pumps were brand new when installed and started leaking almost immediately. We have worked with Paratherm who is the thermal fluid supplier. We also worked with Dean pump, John Crane, and MP Pump. This is why we are at the point now of trying to hire someone to look at our system.

Hey guys, We have a thermal fluid pump at our plant that is leaking from the shaft seal. We have tried 2 different brand pumps now with the same result. It is a slow leak from the shaft seal. Both pump manufacturers have tried looking at the information for the system with no ideas. When...
