High Strength and High Toughness Casing
As the depth of drilling increases, the load on casing is getting much higher, Meanwhile, the geological conditions are becoming much more complex, especially in oil and gas wells with high formation pressure or abnormal formation pressure, such as sock salt layer, mudstone layer and high pressure water injection wells, casings of common API standard are difficult to meet the requirements. Therefore, developing high strength and high toughness casing to meet the market demand is really necessary.
In the direction of "high strength and high toughness', through the process control technology such as 'clean steel + controlled rolling + heat treatment", combined with microstructure and property control method of "fine grain strengthening + solid solution strengthening + precipitation strengthening + phase change control", Glory Tube develops a series of high strength and high toughness casings with excellent performance such as 110V, 125V, 140V, 150V, 155V, 165V, etc.
Uses
Used for deep wells, utra-deep wells, oil and gas wells with complex geology.
Names
High strength and high toughness casings include GL110V, GL125V, GL140V, GL150V GL155V, GL165V.
Naming rule
GL+Strength+V
Meanings
GL - GLORY TUBE Non-API series
Strength -Specified minimum yield strength (the unit is KSI and trimmed to multiples of 5)
V - High strength and high toughness
Product size
The range of OD for the Glory Tube's the high strength and high toughness casing: 4 1/2'~13 3/8".
