High Strength Alloy Steel Pressure Test Spool

21 1/4"-2000psi BOP Test Stump

The BOP Stump (Blowout Preventer Pressure Test Spool) is a specialized flange spool designed exclusively for pressure testing blowout preventers (BOPs) in off-site locations such as wellsites or remote areas—eliminating the need for testing within the factory premises.

As a critical auxiliary component for BOP maintenance and compliance verification, it serves as a compact, robust connection interface between the BOP and pressure testing equipment, enabling the creation of a secure, closed-loop system to validate the BOP's pressure resistance, sealing integrity, and overall operational reliability.

Key Features & Benefits

Dedicated for BOP pressure testing in wellsites or off-factory locations (no on-site factory required)
Precision-machined alloy steel construction: withstands high test pressures and harsh outdoor conditions
Universal flange compatibility: fits most standard BOP configurations (annular, ram BOPs, BOP stacks)
Compact & portable: easy to transport and install, optimizing on-site testing efficiency
Leak-tight design: ensures accurate pressure testing and reliable validation of BOP sealing performance
Compliant with API and industry standards: guarantees safety and compliance

Technical Specifications

Engineered to meet oil and gas industry standards (including API specifications) and compatible with most standard BOP flange sizes, the BOP Stump features a precision-machined flange connection that ensures a leak-tight fit with BOP assemblies of various types (annular, ram, or stack configurations).

Constructed from high-strength alloy steel, it delivers exceptional structural stability and pressure-bearing capacity, capable of withstanding the high test pressures required for BOP qualification—ensuring safe and accurate testing results even in harsh wellsite conditions (e.g., extreme temperatures, outdoor environments).

Its compact and lightweight design facilitates easy transportation and on-site installation, eliminating logistical challenges associated with moving large testing equipment to remote locations. The spool's simplified structure minimizes assembly time, allowing operators to quickly set up the testing system and complete pressure verification procedures—streamlining maintenance workflows and reducing downtime for BOPs in active service.

Whether used for pre-deployment qualification, post-maintenance verification, or routine compliance testing, the BOP Stump provides a reliable, cost-effective solution for ensuring BOPs meet strict safety and performance standards. It is fully interchangeable with standard BOP flange connections, making it a versatile tool for drilling contractors, well service companies, and BOP maintenance teams operating in wellsites or off-factory environments.
