Why Partner with Besdrill?
Besdrill bridges the gap between manufacturers and end-users, combining product expertisewith supply chain efficiency.
Ideal for clients who need:
1.Reliable supply of API-certified casings without factory commitments
2.Technical guidance for project-specific requirements
3.One-stop procurement with end-to-end logistics
Petroleum casing is used to support the wellbore of oil and gaswells in order to ensure the normal operation of the whole well after drilling and ompletion. Each well should use several layers of casing according to different drilling depth and geological conditions. Cement cementing is used after casing goes down. It is different from tubing and drill pipe. It can not be reused. It belongs to disposable consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes.
According to APIspec5ct standard of American Petroleum Society,casing can produce processed steel grade J55, K55, N80, p110, etc.Specifications from 60 to 508 K55 can be processed button type STC (short round buckle), LC (long round buckle), BC (partial ladder buckle), VAM (partial ladder buckle) and ther button type.
1. High-Strength Material & Structure
Manufactured from premium alloy steels (API grades J55, K55, N80, P110) with heat treatment and cold-working processes for superior tensile/collapse resistance.Withstands extreme downhole stresses in deep/ultra-deep wells and high-pressure formations.
2. Superior Sealing Performance
Thread connections (API BTC/LTC/STC or premium gas-tight threads like VAM/FOX).Prevents fluid migration and maintains wellbore integrity under high pressure.
3. Corrosion & Wear Resistance
Protective coatings (epoxy/zinc) or sour-service grades (C90/T95) for H2S/CO2/saltwater resistance.Extends service life and reduces downhole failures.
4. Comprehensive Size Range
Available in OD with customizable wall thickness.Adapts to all well types from shallow to ultra-deep applications.
5. Standardized Certification
Complies with API 5CT/ISO 11960 with mill test reports (MTRs).Guarantees quality and global acceptance.
6. Cost Efficiency & Easy Installation
Modular design for rapid deployment; some types are reusable.Reduces total drilling costs and improves operational efficiency.
Oil casing pipes are critical components in well completion and production operations, providing structural support and zonal isolation.
