Product Description

SD type drill pipe clamp

The SD drill pipe chuck (also known as the SD drill pipe slip or drill pipe slip) is a core safety load-bearing component for wellhead operations on oil drilling platforms. It is specifically designed for tripping and casing operations of 2 3/8-inch to 7-inch drill pipes. Through its graded structure, it adapts to different well depth requirements and provides stable support for the drill string with high-strength clamping and safe load-bearing capacity. It is a key wellhead equipment to ensure the safe and efficient operation of onshore and offshore drilling platforms. The entire series of products are manufactured in strict accordance with API Spec 7K “Drilling and Wellhead Equipment Specification”, ensuring compliant and reliable quality.

 

Key Product Features

  • Graded Adaptability, Multi-Purpose Clamping: Three series covering all well types from shallow to deep wells, compatible with 2 3/8″-7″ drill pipe sizes, providing one-stop solution for all drilling needs.
  • High Strength and Reliability: Constructed from high-quality alloy steel, impact-resistant and wear-resistant, stably clamping the drill pipe, eliminating slippage risks, and ensuring safe wellhead operations.
  • API Standard Compliance, Quality Assurance: Strictly adheres to API Spec 7K. Standardized, reliable performance, and long service life, reducing equipment replacement costs.
  • Compatible with all scenarios and highly versatile: Covers all types of drilling platforms on land and offshore, adaptable to various drilling rigs, drill pipes, and operational requirements.
  • Easy installation and efficient operation and maintenance: Standardized structure, simple installation and disassembly, low maintenance costs, and improved wellhead operation efficiency.

 

Applicable Scenarios
