Hello,
I am looking for information regarding acceptable allowances for hydrogen and nitrogen in low alloy steels such as 41XX, 43XX, or 86XX. There is quite a bit of information on how these atomic gases are introduced during the steelmaking process, and what effects they have on the quality...
I have been trying to create a Mathcad worksheet using the formulas provided in this recommended practice, namely those formulas in Appendix A.8.
As with most API specifications, the formulas do not lend themselves to use in Mathcad if you wish to use a unit system. If you attempt this, and I...
Recently I discovered that a large manufacturer of commercial and industrial driveline components machines companion flanges out of AISI 1141 resulfurized steel. The part in question is something we would like to manufacture in house but I have doubts about using the same material based on the...
Howdy,
Recently a customer asked me to verify that our valves meet the requirements of NORSOK R-001 sec 5.1.5 for the nozzle loads. Essentially this confirms that the valve design is sufficient to support minimum moment and force loads at the nozzle to body (shell) junction that other...
Let's say I have a simple oil pump connected in a closed system with a heat exchanger. The pump adds 127,000 Btu/hr of heat through friction and the heat exchanger removes the heat at 46,140 Btu/hr. What else do I need to find the steady state operating conditions of this system, i.e., the max...
I am trying to do some calculations to quantify the rate at which heat is added to cooling/lubricating oil in a positive displacement (plunger type) pump. The largest contributing factors should be the oil viscosity, rpm of the pump, and time the pump is running. Our typical system can be...
