You also want to consider looking into corrosion resistant parts to decrease downtime in production. One of the best corrosion resistant parts to look into is the hard-faced polished rods. With a nickel coated 4140 steal you can expect a much longer life in the rod. These rods work well in corrosive locations including salt water. You can also buy valve rods with nickel coated for corrosion resistant as well as almost every part you can think of. The most important factor in inspecting the polished rods is checking the diameter of each rod to insure the correct size. If the polished rod is too big then you take the chance of busting the stuffing box and increasing downtime. Make sure the supplier knows this importance and also has some kind of certification as in the API certification.

Finding the right company to work with does not have to be that hard. You just need to search for manufactures and distributors in your area and see what they have to offer. You should ask them about their quality as well as asking them for API certification or a sample of their quality. Having a talk with the manager can review most of this information. Talk with each company and let them know exactly what you need and ask what they have for corrosion resistant parts. They might not produce them but can refer you to a company that does. You can also check out some online market places to scan for good manufacturers and distributors. This is a good place to check out because most of the time they have reviews to check their reputation and this will give you a heads up on if they are a good company or not.
