13 3/8 Inch Casing - J55/K55 Seamless Casing With BTC Thread And R3 Length

1. Product Introduction

Casing and Tubing are critical tubular components designed to maintain the stability and integrity of wellbores during oil, gas, geothermal and groundwater extraction projects. This batch of seamless casing is produced strictly in accordance with ISO 11960 international standard, featuring a nominal size of 13 3/8 inch with an outer diameter of 339.7 mm. The steel grade is J55/K55, with a wall thickness of 10.92 mm, equipped with BTC buttress thread connection and R3 standard joint length, and the total supply length of this order is 528 meters.

As a reliable casing solution for shallow and medium-depth well projects, Casing and Tubing can effectively prevent well wall collapse, isolate different underground formations, avoid cross-flow of formation fluid, and create a safe and stable channel for subsequent drilling, completion and production operations. We support both standard stock supply and customized non-standard tubular products for global oilfield, energy and water well customers.
