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..
Production Capacity: 500 000 tons/year
Dalipal Company is one of the most famous enterprises of china professionally producing pipeline and oil casing.We can supply API 5CT series of pipeline and oil casing with all kinds of specifications and materials.We have first-class production equipment and technology.
