Given below is the T Table (also known as T-Distribution Tables or Student’s T-Table). The T Table given below contains both one-tailed T-distribution and two-tailed T-distribution, df up to 1000 and a confidence level up to 99.9%

We designed steel composition and heat treatment of deep well (DW) grades targeting an optimized yield strength / toughness trade-off: high yield strength and good ductility are granted, together with fracture toughness proved by Charpy testing at specific temperatures.

The molybdenum content for T95 Type 1 may be decreased to 0,15 % minimum if the WT is less than 17,78 mm. For EW Grade P110, the phosphorus content shall be 0,020 % maximum and the sulfur content 0,010 % maximum.

7.2.4 Statistical tensile testing – Grades C90, T95 and C110 By agreement between purchaser and manufacturer the supplementary requirements for statistical tensile testing of Grades C90, T95 and C110 in A.12 (SR38) shall apply.

API Steel Grade – K55, N80, L80, C90, T95, P110, Q125 API, shorted for American Petroleum Institute, is considered as the most authoritative and comprehensive principles for oil and gas industry.

WLD steel is a leading API 5CT casing and tubing manufacturer and supplier, we provide a broad range of API 5CT T95 oilfield casing pipe, API 5CT T95 type1 tubing but also casing coupling, perforated pipe, and more.

Steel grades to classify various steels by their composition and physical properties have been developed by a number of standards organizations. For alloys in general (including steel), unified numbering system (UNS) of ASTM International and the Society of Automotive Engineers (SAE).

Table of critical values for a 2-tailed t -test at 95% confidence level, generated from Excel using the TINV function.

API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries. Besides casing and tubing, it also includes pup joints, coupling stock, coupling material, and accessory materials, and establishes requirements for three product specification levels (PSL-1, PSL-2, and PSL-3).
