ASME B36.19: Understanding the Dimensional Standards for Titanium Pipe Fittings.

ASME B36.19 is a standard specification for stainless steel pipe. It does not specifically cover titanium pipe fittings. However, titanium pipe fittings are commonly manufactured to similar dimensional standards as stainless steel pipe fittings, and manufacturers often adhere to similar ASME standards for dimensional specifications.

For titanium pipe fittings, manufacturers typically follow ASTM B363, "Standard Specification for Seamless and Welded Unalloyed Titanium and Titanium Alloy Welding Fittings." This specification covers the dimensions and tolerances for seamless and welded titanium pipe fittings, including elbows, tees, reducers, caps, and stub ends.

Here's an overview of some key aspects covered by ASTM B363 for titanium pipe fittings:

1. Scope: The specification covers seamless and welded unalloyed titanium and titanium alloy welding fittings for general corrosion-resistant and elevated-temperature services.

2. Material Grades: ASTM B363 applies to various grades of titanium and titanium alloys suitable for welding fittings, including Grades 1, 2, 3, 7, 9, 11, and 12.

3. Dimensions and Tolerances: The standard specifies the dimensions, tolerances, and wall thicknesses for various types of titanium pipe fittings, ensuring consistency and compatibility with piping systems.

4. Manufacturing Processes: ASTM B363 outlines the manufacturing processes for titanium pipe fittings, including forming, machining, heat treatment, and surface finishing.

5. Testing and Inspection: Requirements for testing and inspection procedures are included in the standard to ensure the quality and integrity of titanium pipe fittings. This may include visual inspection, dimensional checks, and non-destructive testing methods.

6. Marking and Certification: ASTM B363 specifies requirements for product marking and certification, ensuring traceability and compliance with specified standards.

While ASME B36.19 does not directly cover titanium pipe fittings, ASTM B363 provides comprehensive specifications for manufacturing and quality assurance of these fittings. Manufacturers typically adhere to ASTM B363 or other relevant ASTM standards when producing titanium pipe fittings to ensure dimensional accuracy, material quality, and performance consistency.
