Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.


EEJ EXPANSION JOINT  

INTRODUCTION

Expansion Joint is designed for use in both single and dual string completions to compensate for tubing movement. The tool provides 10ft of movement, and utilizes rugged module seals for reliable continuous service. The telescoping action permits the tool to be used as a bumper sub or jar when retrieving the installation. Shear screws may be installed to initially position the expansion joint in its extended, collapsed or mid-position. A rotation lock lets the operator rotate through the expansion joint in any position.

FEATURES

• Shear screws easily added or removed to adjust shear value

• Tool can be locked in fully extended, fully collapsed or mid-stroke position with shear screws

• Full length keys provide transmission of torque through full length of travel
