We were asked to develop a torquing procedure to follow PPC-1. But now our customer asking to submit a traning certificate.
We're basically bolting about 40, 2", 3" and 4" flanges. Does ASME PPC-1 require a certificate?
The thermal expansion calculations for pressure vessels are based on an empty vessel. If the empty vessel is in a fire and the gas stored starts to expand rapidly the relief valve will protect the vessel from damage.
However, what if the vessel is filled with a solid like desiccant in a...
We are using a GMAW procedure to seal weld a container's sheet metal wall. We had to submit our procedure for review.
We've been asked to submit a copy of the macrophotograph of the weld used in qualifying the procedure. Unfortunately, we did not get it done as we were only using the procedure...
We're working on a project where some 225kW rotary compressors are operating outside. The ambient temperature will vary from 21 to 93 degrees F throughout the year. When operating the compressors will be operating at approx. 205 degrees F. The units have freeze protection and will not be...
We have to weld grounding lugs on our package skids. Usually we weld a small stainless steel pad in the corners for the customer to ground to. We have been asked to supply a copper faced ground.
We would rather not go to a plating company as we have such a small quantity of pieces. Does anyone...
We're trying to design a small control panel for use in an ATEX Zone 1 area. So far we've found all the end devices that are suitable for this area.
We usually use an Allen-Bradley Micrologix 1500 in the US as we only have 5 inputs/7 outputs and 2 anlaog inputs through an expansion module...
We are being asked to supply the allowable nozzle load at a vessel contained inside a package skid. This nozzle connection is supported within 5 feet as the piping changes direction. We've supplied the allowable nozzle loads at skid edge connnections, which is where the customer will hook-up...
We are working on a project supplying air compressors to a European company. One of their engineers is asking for a certificate of conformance for the inlet air filter.
I've gone to the filter manufacturer and do not know what I am requesting. Does anyone have any idea what this form looks like...
Has anyone had any luck in finding a HMI that can operate in a 60ºC enviroment and is rated for a Class 1 Div 2 area. Cooling through a vortex cooler is not possible as there is no excess air.
Thanks in Advance
We are being asked to supply a Certificate of Conformance on an inlet air filter for an air compressor. The filter supplier has test conforming to SAE J726, but not to the new ISO 5011 standard. What does this certificate look like, so I can instruct the filter supplier.
I'd like to know if there is a guide explaining how the C&E diagrams are to be created. On simple cause effect systems it looks straight forward. However, in systems where one cause can have multiple effects which in turn can have secondary effects it becomes more difficult.
Any help would be...
Need assistance in calculating how to size a relief valve on the water size of a sheel & tube heat exchanger for a sudden rupture of one of the pressurized tubes on a 3-stage compressor cooling system.
The internal pressure is 3000psig and the closed loop water pressure is 70 psig. A water...
We're working on a process where nitrogen is extracted from compressed instrument quality air by removing O2 from the air. This extracted oxygen along with regular air is vented to atmosphere through a carbon steel pipe at near atmospheric pressure. This process increases the precentage of...
We are supporting conduit going to a 1/2" GUA fitting on one end and hanging a solenoid off the other end. The support is within inches of the GUA fitting. Our inspector is saying that the GUA fitting must be supported at two points to comply with NEC 314.23(E).
I like to ask whether a GUA...
I work for a company that design and fabricate skids for compressed air systems. These packages range in size and complexity dependent on the number of compressors/dryers and associated equipment requested.
Due to the amount of piping our packages have the main skids are designed to minimize...
