ASTM B338 Seamless and Welded Tubes It is a type of titanium and titanium alloy pipe that was created to meet the needs of an application where corrosion failures, fouling, and inefficient heat transfer could not be tolerated. These tubes are mainly designed to work in seawater, evaporators, heat exchangers and condensers environments that are very acidic, chloride and brine environments.
ASTM B338 was developed to address a different issue, unlike the stainless steel tubing standards, which are based on pressure piping or instrumentation, namely, long-term reliability in aggressive service in the heat-exchange. Being the leading ASTM B338 Seamless and Welded Tube Manufacturers in Bangalore, India , Shubham Metals provide tubing with ASTM B338 to the industries whose material degradation directly affects the overall availability of the plant, safety, and operating cost.

Why ASTM B338 Is the Preferred Standard for Heat Exchanger Tubing
ASTM B338 is not a general titanium tube specification. It is narrow minded and it deals with heat-transfer equipment in which tubes are subjected to:
- Continuous fluid flow
- Elevated temperatures
- Cyclic thermal stresses
- Highly corrosive media
The natural oxide coating gives titanium highest level of resistance to pitting, crevice corrosion and biofouling and ASTM B338 tubing has become an established substitute to copper alloys and stainless steels in severe systems.
As a buyer, one usually uses ASTM B338 when:
- Replacement of tubes is very expensive.
- Close-downs are very costly.
- Expectancy of service life is more than 20-30 years.
Seamless vs Welded ASTM B338 Tubes: How Buyers Decide
ASTM B338 permits smooth and welded tube fabrication that gives designers the performance and cost leeway.
1. Seamless ASTM B338 Tubes
Seamless tubes can be produced using solids of titanium billets by extrusion and cold working. The tubes have no weld joint and hence uniform metallurgical properties across the cross-section.
They are usually defined with regards to:
- High pressure condenser systems.
- Important uses of evaporator.
- Nuclear-related services and power plants.
When the failure tolerance is very low then seamless tubes are usually chosen.
2. Welded ASTM B338 Tubes
Welded tubes are made of flatted titanium strip which is formed and welded through controlled automatic welding processes. Cold working of many of the tubes that have been welded is done after welding which greatly enhances the integrity and performance of the weld.
They are preferred for:
- Bundles of heat exchanger large diameter.
- Desalination plants
- Industrial projects optimized in terms of costs.
In most heat-transfer services, welded ASTM B338 tubes may be reasonably trusted to work when sufficiently manufactured and tested.

Titanium Grades Commonly Used Under ASTM B338
ASTM B338 is available in several grades of titanium to meet different grades of corrosion and strength needs.
|
Grade |
Typical Selection Reason |
|
Grade 1 |
Maximum corrosion resistance, high ductility |
|
Grade 2 |
Best balance of strength and corrosion resistance |
|
Grade 2H |
Higher pressure resistance than Grade 2 |
|
Grade 7 |
Superior resistance in reducing and acidic media |
|
Grade 12 |
Improved crevice corrosion resistance |
The appropriate grade has a direct impact on tube life, maintenance rate and overall cost of operation. Shubham Metals helps buyers to select grades using fluid chemistry, temperature and system pressure.
