Advantages of Tubes What is a tube? Tubes are great for transporting fluids or protecting electrical or optical connections and wires. Although slight differences exist, the words “pipe” and “tube” are practically identical – in general, a Tube has more stringent technical standards than a pipe. In today’s fluid systems there are a lot
OCTG Pipes Types What are OCTG pipes? Oil country tubular goods are pipes used for onshore and offshore oil & gas upstream operations (extract oil and gas from the wellbore). OCTG pipes may be classified into three main families: drill pipes (to perforate the soil and reach the reserve), casing pipes (to consolidate the well and
Types of Oil & Gas Pipes: Seamless, ERW, LSAW Learn about the 3 types of steel pipes used in the petrochemical industry: seamless, ERW (electric resistance welding), and LSAW (longitudinal submerged arc welding). A seamless pipe is manufactured by drawing a solid steel billet through a piercing rod. Welded pipes are produced by cutting,
Safety Valve and PRV (ASME/API 526) Safety Valve A safety valve is protection equipment that is invented to control the pressure in operation. This valve protects people and the environment from overpressure that may produce explosions or different damages. When a set pressure exceeds, a safety valve opens automatically. A safety valve is the
OCTG Sour Service Steel Grades
13Cr Steel In Oil And Gas In most conditions when the partial pressure of CO2 is above 30psi, carbon steels present high corrosion rates. Steel grades alloyed with high contents of Chromium (Cr), Molybdenum (Mo) and Nickel (Ni) are able to effectively resist corrosion. 13Cr Steel OCTG Pipe made with 13% Chromium (13Cr) are
Differences between Oil Casing Pipe and Oil Drill Pipe There are two main differences between oil casing and oil drill pipe: 1. Different uses; 2. Different materials; 3. Different functions. Petroleum casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire
Duplex Stainless in Oil and Gas The oil and gas industry remains by far the largest user of duplex stainless steels. Standards such as Norsok and NACE (Appendix 1) provide detailed instructions for the selection of materials. They range from carbon steels, stainless steels (martensitic, austenitic, duplex, super austenitic) to nickel-base alloys depending upon
API oil pipe specification and non-standard specification API oil pipe specification system API Standard is a general term for specification (SPEC), recommended practice (RP) and notification (BUL). "Specification" To facilitate communication between purchasers and manufacturers, to provide interchangeability between the same equipment and materials purchased from different manufacturers and produced at different times; and
What is the API standard for petroleum steel pipe? Petroleum steel pipe Petroleum pipe is the general name of oil-specific pipe (casing, oil pipe, drill pipe, square drill pipe, weighted drill pipe, drill collar, etc.) and pipeline pipe for oil and gas transmission, which runs through all aspects of oil drilling, well completion, oil
