Welded Steel Pipe for Gas Oil Line
Welded Steel Pipe for Gas Oil Line
When it comes to gas oil line, welded steel pipe is one of the best choices for transporting high-pressure, pressurized gas.welded steel pipe for gas oil line It is a very reliable, durable and cost-effective method of transferring natural gas across long distances. It is capable of withstanding harsh environmental conditions and can be safely used underground, onshore or offshore. It also features a wide range of mechanical properties, including high strength and toughness, excellent weldability, low-temperature resistance and corrosion (CO2), seawater resistance, and HIC, SSCC performance.
Welded pipes are constructed in two stages — first, the steel sheet is cut into a length of pipe, and then the weld seams are fused together using hot passes.welded steel pipe for gas oil line The weld seams are inspected to ensure that they have been thoroughly penetrated and sealed, and the pipe is then heat-treated to prevent rusting and extend its lifespan.
Most of the oil and natural gas that is used in the United States is transported by pipeline. In fact, more than 95 percent of the natural gas consumed in the country is transported this way, while nearly 70 percent of the petroleum is moved this way as well. The vast network of pipes used to transport these substances is extremely complex and requires a great deal of engineering and construction expertise.
There are a number of different types of welded steel pipes, but the most commonly used type is longitudinally-welded. This type of pipe starts out as a long, coiled ribbon of steel called a “skelp.” Then it is cut to the desired length, and the width of the shorter ends is used to calculate the final outside diameter. The skelp is then fed into a rolling machine that curls it into a rectangular sheet of metal.
From there, the steel is formed into a pipe by welding along the weld seams. The pipes can be made of either carbon, chrome-moly or stainless steel. They can have an outer diameter ranging from 1/2 in. to 36 in. and a wall thickness of up to 4 in.
Pipe manufacturers produce welded steel pipes to meet a wide variety of industry standards, from commercial gas to the latest API specifications. Some of the most common standards include ASTM, AWWA and ANSI. In addition to these standards, the pipe is often subjected to several quality assurance regimens, including a hydrostatic test, exterior size inspection and X-ray testing.
While welded steel pipes are an effective method of transporting oil and gas, many people have misconceptions about the durability of these pipes. For example, some people believe that welded steel pipes are much weaker than their seamless counterparts because of the weld seams. However, this is a misguided belief because welded steel pipes undergo extensive quality assurance regimens to ensure that the weld seams are strong and don’t cause the pipes to fail. In addition, welded steel pipes are tested for leaks to ensure that they are safe to use.
