The Blast Joint is a vital component in oil and gas operations, designed to provide protection to the tubing string and minimize the impact of external erosion from flowing fluids. It is constructed using high-quality steel with a hardness level ranging from 28 to 36 HRC according to NACE MR-0175.
This ensures its durability and integrity under harsh conditions.
By strategically placing the blast joint opposite to the well perforations or below the tubing hanger during sand fracturing operations, it offers an additional layer of defense to the tubing string. The blast joint's heavy-walled tubing construction safeguards against erosive forces and prevents damage to the production equipment.
To maintain the full-bore inner diameter of the tubing, the blast joint is designed to have the same outer diameter as the couplings connected to it. This allows for smooth fluid flow through the system without any significant restrictions.
In situations where the presence of hydrogen sulfide (H2S) is a concern, Landrill has the capability to produce blast joints specifically designed for H2S services. These blast joints are made from heat-treated materials with a hardness level between 18 and 22 HRC complying with the specifications outlined in NACE MR-0175. Adhering to these standards ensures the joint's resistance to the corrosive effects of H2S and maintains the overall integrity of the tubing string in H2S-rich environments.
Overall, the blast joint is an essential component in well completions and production operations, offering protection and longevity to the tubing string while maintaining optimal flow characteristics.
