ERW steel Pipe
ERW pipes are manufactured from the longitudinal welding of steel. The welding process for ERW pipes is continuous as opposed to welding of distinct sections at intervals. ERW process uses steel coil as feedstock.
ERW Pipes and hollow sections produced by our sources are widely used for low pressure fluid transportation and construction projects
LASW steel Pipe
There are two technologies that can be used to manufacture steel pipes of sizes larger than the steel pipes that can be produced by seamless and ERW processes. The two types of pipes produced through these technologies are Longitudinal submerged arc welded (LSAW) and Spiral submerged arc welded (SSAW) pipes. LSAW are made by bending and welding wide steel plates and most commonly used in oil and gas industry applications. Due to their high cost, LSAW pipes are seldom used in lower value non-energy applications such as water pipelines.
SSAW Steel Pipe
There are two technologies that can be used to manufacture steel pipes of sizes larger than the steel pipes that can be produced by seamless and ERW processes. The two types of pipes produced through these technologies are Longitudinal submerged arc welded (LSAW) and Spiral submerged arc welded (SSAW) pipes
SSAW pipes are produced by spiral (helicoidally) welding of steel coil and have a cost advantage over LSAW pipes as the process uses coils rather than steel plates. As such, in applications where spiral-weld is acceptable
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
Casing is the major structural component of a well. Casing is needed to:
Casing provides locations for the installation of:
The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors, and setting depth is a primary engineering and economic consideration.
Tubing is the conduit through which oil and gas are brought from the producing formations to the field surface facilities for processing. Tubing must be adequately strong to resist loads and deformations associated with production and workovers. Further, tubing must be sized to support the expected rates of production of oil and gas. Clearly, tubing that is too small restricts production and subsequent economic performance of the well. Tubing that is too large, however, may have an economic impact beyond the cost of the tubing string itself, because the tubing size will influence the overall casing design of the well.
