I'm trying to determine why weld penetration values for fusion welded (TIG and LASER) tubes retaining a rupture disk don't meet min wall thickness requirements to handle internal pressure. A thin disk is compressed between two cylinders/tubes and the three parts are fused together with required...
I am designing a face seal for a test fixture using 017 )-Ring with a .070 diameter cross-section. Parker recommends the corner radii of the groove should be at least three times (ideally six times) the cross-section diameter of the O-ring to avoid over-stressing the ring. This doesn't make...
Has anyone ever used heat-treated steel certification having Tensile and Yield strength minimums calculated from the tested Brinell hardness value rather than a physical strength test? Is this accurate enough to say steel meets the certification minimums if the conversion meets the min?
The...
I'm trying to find out why an all-monel butt weld joint with no filler, just fused, is so much harder to get penetration depth than other CRA materials welded to Monel. We are fusing a .85 OD x.010 thick solid monel disk between two.850 OD x 1/2" ID monel tubes. We just fuse the parts...
Does anyone know what the Tubing End Dimensions are for an AS5202 BOSS?
Parker Tech told me this, "we do not make plugs for AS5202, only for J1926. AS5202 is an aerospace standard and we do not currently make fittings according to aerospace standards". I thought the same tubing end was used...
I need dimensions for AS5202 ORB Plug or male fitting but can't find them on the internet. I found the fitting end AS4395 in Parker O-Ring Handbook Table 4.4 but Parker says only the o-ring size applied to the AS5202 port and not the dimensions. The AS4395 male end fits the AS5202 ORB but the...
I have a male tapered thread that contains brass shavings and burrs in between thread flanks. Is there a common method to clean out shavings from between the threads of the male thread and also for the same problem in the tapped hole? Mcmaster -Carr has sanding wheels for Brass and Bronze but...
I HAVE A .005" 316 SHEET SANDWHICHED BETWEEN TWO 1/4 316 DISKS. ALL THREE PARTS ARE JOINED WITH FUSION WELD AND PARTS HAVE SHARP EDGES SO THE MATERIAL CAN FUSE EASILY.
PROBLEM: INLET DISK SHARP CORNER HAS A .031 DEEP X .015 STEP WHERE THE .005" THICK DISK SHOULD MAKE CONTACT AND BE FUSED...
I have a 1/2 NPT Male Brass fitting with NPT thread cut with wrong taper (2.2 instead of 1.788 degrees). Looks like it was single pointed and they attempted to fix them with a die but that's just a guess. It gages within +/- turn to face of thread but worries the incorrect taper will allow it to...
I need to design a 1" Sanitary connection onto 3/4" Tubing Fitting. I'm looking for geometry and dimensional data for this connection. I believe its a clamp type fitting and is similar to having a flange on each end. Can any one provide a link where this can be found? I found some info but...
I have fittings with 1.5" long 1/4 OD tubing ends with drilled ID to .13" The drilled finish is maybe a 250Ra. The drawings call out 63 Ra everywhere. I bought the parts off as this is just for flow and won't affect flow performance significantly. Our QC engineer is having a fit saying...
I have hears two different opinions of that the downhole wellbore temp will be after treating with cooler fluids like acid and fracing.
If you were fracing though a sleeve, packer or other device with seals, would you expect the temperature of the wellbore equipment to drop durig treatment?
I...
Question about o-ring frictionz;
1) Is friction higher at temperature or ambient considering factors like thermal expansion of gland? O-Rig Material is Viton 90 and Virgin Peek back-ups
2) High temp is 350F
3) Gland has 32 RMS and 14%-20% squeeze
4) Fluid is hydrocarbons and then acid
4) I...

Look a oilfield inflatables. They design the bladder (rubber tube to expand to about .060" thick when expanded. The strength come from a steel slat back-up, or a weave cable back-up impregnated in rubber cover. alone, the rubber is too weak and expands unlimited until it...
I'm looking for advise on how I can take a temperature measurement inside the ID near a circuit header board on a pressure sensor. The EB Weld machine makes it difficult to see anything and it done in a sealed vacuum.
Here are the specifics and a pic showing where I want to get a measurement...
There is a method to select a plane or planes and orient a view. I don't remember what tool to select to orient the part based on the planes I selected. For instance, I could select a plane that is at 45 degrees with front view, select the plane and then select tool and tell it to make new...
I have a question about a pressure transducer reading that doesn't make any sense. I have a Pressure sensor soaked in water at 125c and 11,000 psi for 24 hours (See images). When bleed off, gauge pressure is 1,000 psi less than sensor pressure. Is there any way that atmospheric pressure cold...
