Impossible de charger la disponibilité du service de retrait
The 2" Figure 1502 Female (Threaded) Blind with a 1/2" NPT Tap is a specialized high-pressure flowline component designed to provide both secure system termination and a convenient access port for instrumentation. Often referred to as a tapped bull plug, this blind securely seals 2" Figure 1502 hammer union connections and features a precision-machined 1/2" NPT female port integrated into the center of the face.
Rated for a Cold Working Pressure (CWP) of 15,000 PSI, this component is engineered for the extreme environments of hydraulic fracturing, cementing, and well-testing operations. The 1/2" NPT tap allows operators to directly install pressure gauges, transducers, or small-diameter bleed-off valves without the need for additional crossover adapters. This integration reduces the total number of leak paths in a high-pressure manifold, enhancing overall site safety.
Manufactured from high-strength forged alloy steel, the 2" 1502 Tapped Female Blind ensures structural integrity and a blowout-proof seal. Its threaded (female) hub profile is fully interchangeable with all industry-standard 2" 1502 male union ends, providing a robust solution for monitoring and managing pressure at the dead-end of a flowline.
Features & Benefits

Applications
This 2" Figure 1502 tapped female blind is essential for high-pressure operations requiring system closure and pressure diagnostics. Typical uses include capping off fracturing or cementing manifolds while providing a port for pressure transducers, acting as a bleed-off point for trapped air or gas, and facilitating chemical injection into isolated flowline segments.
Quality Assurance
Each tapped blind is manufactured under rigorous quality control protocols and undergoes dimensional inspection and non-destructive testing (NDT) to ensure the integrity of the hammer union profile and the NPT thread under extreme high-pressure conditions.
