Thanks for the comment JP. Actually, this damaged laby seal was only discovered during bearing dis-assembly, there was no issues raised with leaking seals. The only difference in the seal design is changing of ring materials...Aluminum vs. Brass. My concern is protecting the condition of the...
Hi, I have a large 3ft diameter turbine bearing that has a damaged non-contact mechanical Labyrinth seal that uses multiple brass rings in the assembly. My machine shop is proposing to replace the lab seal with a 1 piece aluminum housing out of 6061-T6 with the grooves cut directly into the...
Hi,
I'm currently designing a permanent pipe dock to be installed at the cabin...In addition to considering buckling, I need to consider ice loading...Does anyone know what the design pressure due to ice loading on marine structures is? Is this load dependant on the body of water (My location...
Hi Guys,
Our design group has recently provided a criteria regarding the use of SMAW electrodes and MIG wire consumables with the restriction of less than 16ml/100g of diffusable hydrogen and we are trying to conclude if the consumables we have in stock meet these specs.

I'm looking for some feedback in regards to standard cavitation repair practices for turbine runner blades in the hydro electric industry. There are various opinions regarding pre-heat of runners prior to a gouging operation and welding Stainless overlays onto cavitated areas.
Typically our...
PROBLEM: Unfortunately site has no more 1.5" square PTFE braided packing in stores for their water seal stuffing box, located on one of their hydraulic turbine units.
Shipping is 7-10 days and they need the unit online ASAP. The question is, can we compress 1.25" square braid (in stock) to fit...
I recently have been performing design calculations for a small cast iron link with an applied bearing load (pins)on each end, compressing the link. 2.375 OD bushings are spaced 6" center to center at the link ends. cross section of the link 3" x 1.5" thick.
Using Eulers formula for pin ended...
Yates, This is a 100yr old grey cast iron casing. Unfortunately I don't have confidence that a weld repair will provide a successful fix.
We are currently in contact with several Cast Iron repair companies that specialize in this service. If all else fails, I may have to fabricate a new...
Can anyone recommend repair options for a 12" long crack on a 4" thick cast iron turbine casing? This 17 ton component is located inside a turbine pit which holds a dual francis horizontal runner/shaft assembly. Will a weld repair be successful if preheat is not possible?
Thanks.
Thanks CoryPad
I figured that the stover nut did not require the same thickness than a nylock, since it did not have the 1/4" thick nylon portion on the top face...Do you know whether it has better or worse breaking torque than the nylock?
Are you suggesting that these type of nuts only be...
