Product Features
• OEM Interchangeability: Designed with full compatibility for BOMCO, LSNOV, and similar manufacturer assemblies, enabling direct replacement and minimized rig downtime.
•Durable Alloy Steel Construction: The alloy steel main body provides excellent wear resistance, fatigue strength, and ease of repair through forging-welding.
•Strict NDE Protocols: Mandatory MPI and UT ensure each unit meets stringent structural and safety criteria, reducing risks in field operations.
•API 8C Compliance: Manufactured under API Spec 8C licensing, meeting material traceability, grooving, and inspection requirements. Our API 8C certificate number : 8C-0349.
•Precision Groove Sizing: The groove diameter (38 mm) matches the drilling line, avoiding excessive friction or wear, while optimizing line support and longevity.
Crafted to mirror the fit and function of BOMCO, LSNOV, and other leading OEM assemblies, it ensures seamless interchangeability. This assembly is designed to precisely guide the drilling line,whether it's the fast line or deadline,within the crown block framework, maintaining proper alignment and load distribution. The main sheave body is made from high-quality 45# alloy steel, chosen for superior toughness, fatigue resistance, and weldability, ensuring long term reliability in demanding drilling operations.

Quality Assurance & Compliance
Each TC-315 Guide Sheave Assembly undergoes rigorous inspection protocols before delivery. We perform full Magnetic Particle Inspection (MPI) and Ultrasonic Testing (UT) on all welds and sheave surfaces to detect internal and surface discontinuities, ensuring structural integrity. The rope groove diameter is precisely sized to accommodate 38 mm (11/2 inch) drilling line.
Overall, manufacturing and quality control adhere strictly to API Spec 8C standards, offering global assurance of safety and performance.
