Enpro Pipe. Enpro Pipe is China Based Pipe Supplier, with multinational branches in Korea, United States, South America. We are engaged in distributing steel pipe, OCTG casing and tubing, drill pipe
OCTG Tubing pipe goes inside the casing pipe because it is the pipe through which oil makes its way out. Tubing is the simplest part of OCTG and it is normally found in the segment of 30 ft (9 m), with threaded connection at both ends.
Casing and Tubing At our state of the art, fully integrated manufacturing facilities, we produce steel pipe from 1 1/3" to 28" (outside diameters). Our casing and tubing pipes are manufactured according to API grades and also in proprietary grades including sour , high collapse , chrome and CRA products for special applications.
Jul 03, 2017 · Tubing naturally has a smaller diameter than casing, except for the 4 1/2 inch diameter. An outer diameter of 114.3 mm (4 1/2 inches) is considered a threshold and can be either casing or tubing. Anything smaller is called tubing, anything larger is casing.

What are the differences between casing and tubing? Casing is generally a steel pipe installed in wellbore and is cemented in place to prevent Wellbore collapse, cross flow of fluids between different reservoirs and to control abnormal formation pressures. Tubings are usually run inside casing (cased hole) and serves as a conduit through which oil and gas is produced.
• Casing and tubing attachment materials shall be seamless pipe, unless other type stated on the order. Casing and Tubing is a kind of OCTG pipe Heat Treatment
The API 5CT specification covers seamless and welded casing and tubing pipes for upstream operations (pipes that belong to the OCTG family, as illustrated above).. Let’s review each type of OCTG pipe more in detail. OCTG “CASING” PIPES. Function. OCTG casing pipes are a key structural component for an oil & gas well and have the following scope:
The types of steel for tubes for casing and tubing API 5CTH40, J55, K55 and N80. Chemical composition and mechanical properties of steels Steel is made
Casing and Tubing At our state of the art, fully integrated manufacturing facilities, we produce steel pipe from 1 1/3" to 28" (outside diameters). Our casing and tubing pipes are manufactured according to API grades and also in proprietary grades including sour, high collapse, chrome and
What's the casing and tubing pipe grades?. The API 5CT standard covers seamless and welded casing and tubing pipes for oil and gas transportation.Casing pipes are available in the following materialsH 40, J 55, K 55, N 80, L 80, C 90,T 95 ,P 110, Q 125. Depending on the different condition and the depth of the well,we should use the different steel grades.The corrosion resistance of the
Casing,refers to casing pipe which is tubing that is set inside the drilled well to protect and support the wellstream.The Casing lines the wellbore and thus protects the layers of soil and above all the groundwater from being contaminated by the drilling mud and frac fluids.
Casing pipe and tubing pipe Casing is a large diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
Providing customers an extensive inventory of casing & tubing products through 24/7 availability, expertise, and dedication. B&L Pipeco Services inventories a complete line of API casing and tubing products, manufactured to the most rigorous quality standards. Utilizing our outstanding relationships with a variety of manufacturers and service companies, we can provide our customers with the 
Casing Casing is equally as important as pipe. The goal is to make all of your installations come together faster, easier, and at less expense. Our supplier does this by providing virtually every water well casing component you need in a range of sizes, grades, and specifications to
Casing and Tubing High precision in size and shape ,Good corrosion resistance,High collapse strength,Excellent comprehensive mechanical properties,High connection strength and sealability,Constant mechanical properties at high temperature.
Casing and Tubing Hunting provides a complete service throughout the tubular cycle, combining the provision of tubulars, threaded accessories and connection threading. These items are critical to every stage of the exploration and production process.
The most important mechanical properties of casing and tubing are burst strength, collapse resistance and tensile strength. These properties are necessary to determine the strength of
Casing and tubing are the main parts of the well drilled construction. They are selected for the specific conditions anticipated in a given well. The anticipated production flow rates and economics of the well determine tubing size, which then determines the necessary size of each previous hole and tubular.
