OCGT PIPE


API 5CT L80-1(L809Cr,L8013Cr) OIL FIELD CASING PIPE

We have the ability to detect the whole process. We can fully guarantee the high quality of the products.The API 5CT L80 oilfield casing pipe be made of three Grades,including L80-1 ,L80 9 Cr ,L80 13Cr. these three Grades keep the consistent mechanical properties,but different heat treatment method and chemical composition.

It is well known that oil casing is the important lifeline for maintaining oil wells’ operation. But geographical environment is totally different in different areas and the connection of underground force is very complex. A variety of forces acting on the pipeline together, for example: tension, pressure, bending and twisting stress, all of which require oil casing should reach a higher level of quality. Oil casing’s damage for some reason will cause the oil wells’ production decline; some time seriously it will make well abandonment. So our company produces L80 steel grade oil casing strictly according to the API 5 CT standards.

Usage:

The API 5CT L80 oilfield casing pipe is an advanced type in the process of oil drilling.the mechanical performance is higher than the casing made of J55,N80. with relatively hight price,the product applies to more complicated geological conditions,and runs down deeper into the well. in the exploitation of oil and gas,the use of L80 is less frequent than J55,N80 and other Grades..

Q:What does "buried steel pipe" 6*2SC100 mean?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
SC in principle, it should be called water gas pipe, also called thick wall steel pipe;
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
General use seamless steel tube: is with 10, 20, 30, 35, 45# and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled. Seamless tubes made of low carbon steel, such as 10, 20, are mainly used for fluid delivery pipelines. 45. Seamless tubes made of medium carbon steel such as 40Cr, used for the manufacture of mechanical parts, such as parts of automobiles and tractors. General use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel tubes are delivered in hot rolling or heat treated conditions. Cold rolled in heat treated state.
Q:What are the uses of welded steel pipes?
Ordinary carbon steel wire bushings (GB3640-88) are industrial and civil construction, installation of machinery, equipment and other electrical installation works for the protection of electric wire.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
Strength design of steel pipe by this formula to calculate the maximum normal stress in the steel pipe should be less than the value (based on your choice of different grades of steel, steel strength design value is not the same, this value can also be found through the design manual of steel structure), meet the requirements, it can meet the requirements of steel pipe under the action of bending moment strength.
Q:Can the KBG25 steel tube hold 4 six types of cables?
The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
The difference between ERW (longitudinal resistance welding) and HFW (high frequency welding) is mainly due to the different principle.
Q:Is hot dipped plastic pipe steel?
The hot dipped plastic steel pipe is a steel pipe, and it is made of special antiseptic treated composite steel pipe.
Q:What's wrong with the 3PP anticorrosive steel tube?
That is, polypropylene corrosion resistant coating of steel pipe, the biggest feature of this anti-corrosion coating is good heat resistance.
Q:What does "1.5" steel tube mean?
1.5 inch [1 1/2 steel pipe, outer diameter 48.3mm, 1.5 inches, refers to the pipe bore is approximately the inner diameter (25.4x1.5 = 38.1mm). [DN40] the specific parameters of the steel pipe are as follows;The average wall thickness is: 3.5mm;The minimum wall thickness is 3.06mm,Nominal diameter is 40mm,External Jing is 48.3mm,
