Inspection and Testing Requirements

Hydrostatic or nondestructive (NDT) testing: Each tube must be tested for leaks.
Flattening test: For annealed tubes (sample must not crack or split).
Flaring test: For certain alloys/tempers.
Grain size test: For annealed copper tubes (ASTM E112).
Certification: Manufacturer must provide test results certifying compliance.
6

Dimensional Tolerances

Outside diameter: ±0.1 mm (metric) or ±0.005 in (inch-pound).
Wall thickness: ±10% of nominal thickness.
Length: ±3 mm for cut lengths.
7

Surface Finish

Tubes must be free of scale, cracks, and defects.
Minor imperfections allowed if within dimensional tolerances.
8

Certification & Marking

Each tube must be marked with:

Manufacturer’s name or trademark.
Alloy designation.
Temper.
ASTM standard (B111/B111M).

ASTM B111 Specification Chart

Frequently Asked Questions (FAQ)

What is the ASTM B111 standard?
ASTM B111/B111M is the standard specification for copper and copper-alloy seamless condenser tubes, evaporator tubes, and ferrule stock, used extensively in heat transfer applications.
Which alloys are commonly used for marine environments?
Copper-Nickel alloys like C70600 (90-10) and C71500 (70-30), as well as Aluminum Brass (C68700), are preferred for marine applications due to their superior corrosion resistance in seawater.
Does every tube undergo pressure testing?
Yes, according to ASTM B111, each tube must be subjected to either a hydrostatic test or a nondestructive electric test (like Eddy Current testing) to ensure there are no leaks.
What is the importance of the "Temper" in an order?
Temper defines the hardness and strength of the metal. For example, "Annealed" tubes are softer and easier to bend or flare, while "As-drawn" tubes offer higher tensile strength.
What dimensional tolerances should I expect?
Standard tolerances include approximately ±0.1 mm for the outside diameter and ±10% for the wall thickness, ensuring compatibility with heat exchanger headers and sheets.
Are test reports provided with the shipment?
Yes, certified test reports (MTR) confirming chemical composition, mechanical properties, and test results are available upon request to verify compliance with ASTM B111.
