Woodsroad gave you some great advice. Clearly he knows what he's doing. He did a great job post-processing your photo.
One of the things I would advise is shooting at the same elevation as the pipe with it resting naturally. Don't shoot down at an angle; it creates lens distortion plus the composition isn't as pleasing.
There will almost always be tone in the background, even if you're shooting against a white background The only way to eliminate withing post processing is to use flashes to blow the background out. That means firing flashes behind the pipe. What this requires is using three to four color balanced hot lights in front and over the pipe and using rear-facing flashes to blow the background out. This takes awhile to set up, but it can be done quickly this way (however the equipment expense to do it isn't cheap.)
With all due respect, there isn't a cheap or easy way to make great product photography, especially of pipes. Great photos are time-consuming. You can do good workmanlike images fairly quickly, but they're not going to be killer unless you spend some serious coin on equipment and set-up, and you become very facile at lighting and post-processing.
That's my experience anyway.
