What Are The Different Types Of Oilfield Pipes?
Oilfield pipes are an essential part of the oil and gas extraction process. There are many different types of oilfield pipes, and it can be difficult to know which one to use for your project. This article explores the different kinds of oilfield pipes and their applications.
Seamless Pipes
Seamless oilfield pipes transport crude oil, natural gas, and other fluids from one location to another.
These pipes are made from a single piece of metal, so they don't have any welds or seams. This feature makes them stronger and more durable than welded pipes. Seamless pipes are also less likely to leak, so they are often used in high-pressure applications.
There are two main methods for manufacturing seamless pipes: hot rolling and cold drawing. Hot rolling involves heating the metal until it is hot enough to be shaped into a pipe. Cold drawing is a more precise method that results in a smoother surface finish. It involves pulling the metal through a die that is slightly smaller than the desired diameter of the pipe.
Seamless oilfield pipes are available in a variety of sizes and grades. Grade refers to the strength of the pipe. The higher the grade, the stronger the pipe.
Electric Resistance Welding (ERW) Pipe
ERW pipes are made from a coil of metal that is unwound and then welded together. This process involves heating a steel pipe to forging temperature and passing an electric current through the pipe.
As the pipe is lowered and straightened, the electrodes surrounding the steel meet each other. This interaction creates a solid weld joint used in oilfield applications like well casings, risers, and pipes.
ERW oilfield pipes provide a long-lasting and reliable material that can withstand high-pressure levels while maintaining structural integrity. Additionally, they are resistant to corrosion and chemical damage, making them a highly effective option for use in the harsh conditions of oil drilling sites.
ERW oilfield pipes are indispensable as they ensure the safe and efficient operation of offshore wells, cutting rigs, and pipelines.
Longitudinal Submerged Arc Welding (LSAW) Pipe
LSAW oilfield pipes are large steel pipes used in offshore drilling operations. These pipes are highly durable and can withstand the harshest environments and conditions.
These pipes are made from sheets of steel plate that are first cut to size and then rolled into cylinders. The cylinders are then welded together to create the final pipe shape. This process creates a seam along the length of the pipe where fluids or gasses can escape.
LSAW oilfield pipes are uniquely suited for offshore drilling due to their ability to handle high pressures. They can also withstand corrosion caused by harsh sea environments and chemical lubricants.
So, if you want a reliable option for your company's latest offshore project, LSAW oilfield pipes may be what you need. Contact a qualified oil pipes sales associate who can help you find oilfield pipes for sale and help you understand if these pipes are a good fit for your needs.
