5 Tips of looking after stainless steel

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 […]

Types of casing threads used

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 […]

How is stainless steel made of?

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 […]

A brief introduction of Steel Drill Pipe

Drill pipe is used to transmit power by rotary motion from ground level to a drilling bit at the bottom of the hole and to convey flushing media to the cutting face of the tool. Thus it plays a vital part in the successful drilling of oil and gas wells. 1.Grades and Lengths of Steel Drill Pipe Range 1               18 ft to 22 ft Range 2               27 ft to 3 0ft Range 3               38 ft to 45 ft 2.Mechanical Properties of Steel Drill Pipe Mechanical Properties API Steel Drill Pipe Grade E-75 X-95 G-105 S-135 Yield Strength (minimum psi) 75,000 […]

Stainless Steel Pipe Types

Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing. Based on the end use of the pipe, stainless steel piping is broken down into several categories. Pipes and tubes are sometimes difficult to classify, and tend to be distinguished […]
