TIPTOP manufactures precision control line tubing for hydraulic and chemical injection of onshore and subsea oil and gas wells. The control line tubing is manufactured in a number of different product forms including seam welded and redrawn, seam welded and floating plug redrawn and seamless depending on the customer’s specification and application.
In all stainless steels, chromium and nickel are critical for corrosion resistance and ductility. The addition of >10% chromium transforms steel into stainless steel, creating an adherent and invisible oxide layer that is chromium-rich. This oxide layer forms when chromium in the alloy reacts with oxygen in ambient air. This layer gives steel its stainless character. The addition of nickel provides good ductility and ease of forming and welding.
TIPTOP 316/316L stainless steel tube fittings and instrumentation valves contain more nickel and chromium than minimally required by ASTM standards for bars and forgings.
