Product Description
Titanium Blind Flange For Oil And Gas Pipelines
ASME B16.5 Titanium Blind Flange Overview
Our Titanium Blind Flange Raised Face (Ti Gr2 & Gr7 BLRF) is engineered for oil and gas pipeline applications, meeting ASME B16.5 standards for dimensions, tolerances, materials, marking, and testing.
Material Specifications
- Titanium Grade 2 (Ti Gr2): Commercially pure titanium offering excellent corrosion resistance, formability, and weldability for industrial applications.
- Titanium Grade 7 (Ti Gr7): Enhanced with palladium for superior corrosion resistance in reducing and mildly oxidizing environments, ideal for chemical processing and marine applications.
Product Features
A titanium blind flange is a solid disk flange without a central bore, designed to cap off pipelines or close systems temporarily or permanently.
Key Benefits
- Material: Titanium construction provides exceptional corrosion resistance for aggressive environments
- Design: Solid disk configuration creates a sealed closure for pipelines
- Functionality: Serves as both a pipeline cap and access point for maintenance
- Adaptability: Can be machined to accommodate various pipe sizes and connection types
- Performance: Provides secure, leak-proof seals in harsh operating conditions
Applications
Ideal for chemical processing, oil and gas, marine, aerospace, and other industries requiring durable, corrosion-resistant pipeline components.
