While standard Figure 1502 fittings are rated to 15,000 PSI, this specialized sour service blind is strictly de-rated to a Cold Working Pressure (CWP) of 10,000 PSI in compliance with industry safety standards. It is an essential component for safely dead-ending flowlines and well-testing manifolds exposed to toxic sour gases.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eManufactured from premium forged alloy steel, the entire assembly—including the male blind sub and the heavy-duty wing nut—undergoes a specialized heat-treatment process to meet stringent NACE MR0175 \/ ISO 15156 requirements. This controlled metallurgical process significantly reduces the material's hardness, preventing the catastrophic effects of Sulfide Stress Cracking (SSC) and hydrogen embrittlement that occur when standard steel is exposed to H2S under high pressure. Because it comes pre-assembled with the wing nut, rig crews can immediately deploy the blind to securely terminate pressurized systems.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eDesigned for uncompromising safety in the most lethal upstream environments, the 3\" 1502 Sour Service Male Blind Sub ensures absolute fluid and gas containment, protecting both rig personnel and the environment during sour well testing, flowback, and production operations.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
