Tube & Pipe

Continuous Buttweld

Conforms to ASTM A53 Type F Grade A.
A general purpose pipe, most commonly used in steam, water, gas and air lines.

Electric Resistance Welded

Conforms to ASTM A53 Type E Grade B.
Suitable for welding, coiling, bending, and flaring.

Pipe Size (ERW) Tubing

Conforms to ASTM A500 Grade B.
A structural purpose pipe sized tube. Compared to pipe, this product offers higher strength, better straightness as well as superior finish and at a lesser cost than tested pipe.

Cold Drawn Seamless (CDS)

Conforms to ASTM A519.
Produced to OD and ID dimensions by a process that pierces a hot rolled bar. Normally furnished in the “as drawn” condition. CDS offers good surface quality and greater mechanical properties than hot finished seamless tubing. Made from 1026 grade steel.

Sizes ranging from: 1/2″ x .049″ wall to 10″ x .500″ wall

Drawn Over Mandrel (DOM)

Conforms to ASTM A513 Type 5 (mandrel drawn).
DOM has very little wall variation and no spiraling eccentricity. The tube is formed and welded from strip steel which has very little gauge variation. The tube is then cold drawn to size, causing the weld seam to virtually disappear. Tubing 10 ga and lighter is made from 1020 grade steel, heavier than 10 ga is made from 1026.

ADVANTAGES OF DOM

  • More uniform wall
  • Better surface finish
  • Less stock removal
  • No spiral on ID thickness
  • Denser ID surface
  • Closer tolerance
  • Comparable or lower cost

Sizes ranging from: 1/2″ x .049″ wall to 10″ x .500″ wall

Electrical Resistance Welded (ERW)

Electrical resistance welded tubes are produced from a cold rolled or hot rolled scale-free strip which is formed by rolls at room temperature into a tubular shape. Welding takes place as an electric current heats the two edges of the strip as they are pressed together. Only a narrow band of metal is heated while the rest of the tube remains at room temperature.

Sizes ranging from: 1/2” x .049” wall to 10” x .120” wall

Square And Rectangular Tubing

Conforms to ASTM A513 Type 1 (AWHR) or Type 2 (AWCR).

Mechanical – An electric resistance welded tubing produced from low carbon steel. Offers good surface finish and forming characteristics. All sizes have the OD flash removed, with the ID Flash-in. Generally available in wall thickness lighter than 11ga., in widths less than 3 inches.

Conforms to ASTM A500 Grade B.

Structural – An electric resistance welded tube produced from a structural grade of steel. Offers a high strength-to-weight ratio, yet is easily welded, formed, punched, and drilled. All sizes have the OD flash removed, with the ID flash-in. Minimum mechanical properties: Tensile Strength = 58,000 psi, Yield Strength = 46,000 psi, % Elongation in 2″ = 23%.

Sizes ranging from: 1/2” x 1/2” x .065” wall to 16” x 16” x .500” wall
