Hello,
I have a part which has an outside profile of a straight slot. This part has a top surface and a bottom surface, and has additional machined features not shown in the example. My primary datum, A, is the outside surface of the part. This is similar to ASME Y14.5-2018 Figure 7-3(f), which...
Hello everyone,
I’m looking for help in finding what I can best describe as a pressure compensated flow regulator or pressure compensated flow control valve for compressed air. I know that these valves are readily available for fluid power applications, but I cannot seem to find what I need for...
Perhaps an odd question and I am not sure if the code issues sub forums is appropriate so here we are.
I’m wondering if anyone has experience or thoughts about whether fluid power systems are subject to NFPA 30 code compliance. This would be for systems or equipment utilizing petroleum based...
Hello,
I’m working on the design of an investment casting and have a question regarding interpretation/application of a tolerancing standard to the product. For background, the casting is an investment casting made of CF3 (UNS S30403 Equivalent). Our product definition is IAW ASME Y14.5-2018. We...
Hi there,
Not sure if this the most appropriate forum for this question, but I'm not sure where else to post it.
I'm looking for an air pilot hydraulic valve with minimal resistance to flow for flow rates of 3gpm to 6gpm for oils with viscosities up to 1000-SUS (~ 210-cSt). Ideally, I'd find a...
Hi everyone,
I searched the forums but didn't see anything that caught my eye on this topic. I'm hoping to better utilize our vendors' tube laser machine in the design of frames and components and I want to ensure that I'm modeling the parts in a way that accurately reflects their true form...
Hi there,
Apologies if I'm being dense on this topic, but I can't quite sort this out.
I'm having some trouble understanding how to properly specify carbon steel plate/sheet materials for fabrication (located in the US). I feel as though I can properly specify an austenitic steel plate - but my...
Hello,
I'm tasked with design of a filter (pressure vessel) to meet a specific UL Standard, 331, and only to that standard. To my understanding, the standard covers some requirements and limitations on the construction of the filter, but not to the extent of a code, say for instance ASME BPVC...
Hello,
I've done some research through the forum and have found some helpful information but am looking for some more guidance, if possible. Below is a brief description of the assembly and conditions as well as a few questions.
- A356 cast pressure vessel with an A380 cast lid. The A356...
Hello,
I'm designing a filtration and oil transfer skid for gear oil. The reservoir is located too far from the main lube skid that it would reduce the pump performance due to the long suction line. To correct for this I will install a transfer pump adjacent to the reservoir which will pump the...
Hi there,
New here and looking for some help and direction.
I have a piece of equipment (gearbox) (approx. 10,000 lbs of steel) that holds 50 gallons of oil. I want to heat up the oil and gearbox by kidney looping the oil through an off-line heater. I'm trying to determine how long it will take...
