casing tubing,casing piep for oil and gas


Some of the OCTG covering tubing designed for your company’s demands incorporate:
 
Standard drill water lines, housing piping conforming to API requirements for oils discipline and strong effectively drilling
 
API 5CT L80 outer shell tubes conforming to API specification 5CT having a operated generate energy with solidity test requirement of 23 HRC greatest; generally utilized in wells with sour (H2S) surroundings or strong bitter wells
 
API 5CT N80 or N80 QAndT (Tempered and Quench) - general goal pipe manufactured to API specification 5CT
API 5CT N80 casing pipe,casing tubing
API 5CTNormalized N80 - lower-cost substitute for normal Q&T N80; water pipe walls lower than .500 inch; testing, inspections and dimensions are in accordance with API 5CT for quality N80. Charpy v-notch effect analyze assimilated vitality outcomes conform to API SR16 and therefore are lower QAndT N80
 
 
API 5CT H40 covering tubing - general function piping conforming to API specification 5CT
 
API 5CTJ55 common goal water lines for covering tubing programs, comparable to specification K55 with decrease lowest tensile strength conforming to API specification 5CT
 
API 5CTK55 common purpose piping employed primarily in casings conforming to API specifications 5CT

API 5CT C90 - an API managed deliver energy quality (25.4 HRC highest) typically employed in bad condensate wells; with needed considerable hardness evaluating, SSCC screening for every NACE Regular TM-0177-Technique A; lowest tolerance stress required is 80% of specific minimum deliver strength
 
API 5CT C95 - same durability range as T95 and You. S. Steel C95, but without a hardness requirement; generally not used in sour wells
