TP304L Stainless Steel Seamless Tubing , ASTM A269 Industrial Stainless Steel Pipe

Description:

Spezilla manufacture standard sizes of seamless and welded stainless instrumentation tubing. Our stainless steel instrumentation tubing primarily consist of the austenitic grades of 304, 304L, 316 and 316L, in a size range from 1/4” to 1/2” outside diameters in straight lengths and coils, where applicable. Stainless steel instrumentation tubing is stocked in the annealed and pickled, bright annealed, mill finish and polished conditions. These are the four most popular austenitic grades of stainless steel which provide excellent overall corrosion resistance.

Tubing Grade: 316/316L

Tube OD sizes (Fractional): 1/8, 1/4, 1/2, 5/8, 3/4, 1 in.

Tube OD sizes (Metric): 6, 8, 10, 12, 16, 18, 20, 25 mm

Wall Thickness (Fractional): 0.028, 0.035, 0.049, 0.065, 0.083, 0.095, and 0.109 in.

Wall Thickness (Metric): 1.0, 1.5, 2.0, and 2.5 mm

Applications:

Spezilla's stainless steel instrumentation tubing are sold to a wide range of industries/markets, due to their overall corrosion resistance and good machinability:

1. Power Generation

2. Automotive

3. Chemical and Petrochemical

4. Oil and gas platforms: 

    Process instrumentation and sensing

    Chemical inhibition

    Impulse lines

    Hydraulic application
