Hello all: Looking for help to find a table of heat values for natural gas components that covers decanes ++ Thanks Geoff

I think we should not try and be too clever when buying a pump, that is by trying to show more knowledge than the pump supplier. He has to supply the warranty, and also the spare parts. You can do a "life-cycle" cost analysis to choose between pump package suppliers, and hold the...

I would like to echo ietech's point. There are many regulatory requirements in many countries that negate the possible benefits of RBI. Don't get caught out! Also take care that the employer is not just looking to cut costs with the latest whizzy scheme. A planned preventive maintenance and...

I would also pay attention to the hydraulics of the system. Take care with surge, and don't put any fast closing valves in the line. Especially if you have a few miles of large diameter pipe with water at high velocity.

Thanks for the idea to post a photo, however my employer's website security does not permit putting pictures onto websites. I can email photos to anyone who would care to pass comment on what we got installed. Sure does not look like any weldolet in the bonney forge catalog Thanks...

Thanks, 11echo, I am concerned that we got short changed on the fitting used by the contractor. I have a photo of the installation - I can email it if anyone is willing to let me have their email address and offer opinion on what was installed. I'm not sure if I can attach photos to these...

Contact some paint manufacturers and you will find they offer free info if you are likely to specify their product. Start with a web search and take it from there with manufacturers in your state or local area.

We have experienced weld failure on a number of branch to header connections in thin-wall pipe. The application is 8-inch branches on a 20-inch flare header, where both main run and the laterals are specified as schedule 10S gr. 304 stainless steel.We have had our own problems with welding and...

We have a 24-inch full bore pipeline ball valve in shut-off service in an isolated desert oilfield location. Normal duty is valve closed with 60 bar on one side and 15 bar on the downstream side. Questions / problems: 1. What are our chances of using this valve for a short time to flow into the...

I seem to have a similar problem to yamin. We have a 2MVA oil-filled transformer that has a seam weld leak in the main oil filled steel box part, right underneath where we can only get at it by hoisting up the transformer on a crane. We are in the Sahara desert and back-to-manufacturer repairs...

Do the piping codes permit the use of 6-inch weldolets on a 14-inch line? Application is water injection in the Algerian desert - no statutory codes but they recognise "major" international standards e.g ANSI, BSI, DIN etc. Thanks Geoff
