Stainless steel is durable, low maintenance and can stay looking great for many years, but it still needs to be looked after. You want it to stay stainless, so that the surface keeps it’s original lustrous look, feel and finish. The basics of stainless steel maintenance 1.Apply pickling paste– if you have a small, difficult surface, you can use pickling paste or gels for brush pickling of weld seams. It adheres well and lasts a long time. 2.Apply pickling spray– the spray is better for larger surfaces of most stainless steel grades; it is able to reach even the most […]

Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality.Oil country tubular goods (OCTG) is a family of seamless rolled products consisting of drill pipe, casing and tubing subjected to loading conditions according to their specific application. In oilfield tubing and casings, thread profiles are designed and manufactured in order to provide superior hydraulic seals between the equipment and pipes. There are several types of Casing Threads used; they include: Ⅰ.Buttress […]

Stainless steel is made up of iron alloys, chromium (at least 10.5%) and other metal alloys such as nickel, titanium, copper or molybdenum. Essentially, it’s a family of heat and corrosion resistant metals combined to create an incredibly useful metal. The makeup of stainless steel varies depending on its intended use and corrosion resistance requirements. Stainless steel is available in a range of grades including Austenitic, Ferritic, Martensitic and Duplex. Making stainless steel involves a number of steps Melting&Casting:The iron alloys are first melted together under extreme heat for around 8-12 hours.Once the metals are melted,they are cast into specific […]
