Seamless Tube

Seamless Mechanical Tubing

Our seamless mechanical tubing is produced through an extrusion process where a solid steel billet is heated and drawn over a piercing rod. This method creates a hollow shell without a weld seam, resulting in a tube that handles higher internal pressures and offers superior structural integrity. Unlike standard pipe, our seamless tubing is manufactured to precise outside diameter (OD) and wall thickness specifications.

Standard Specifications & Grades

We stock a full range of carbon and alloy seamless tubing:

  • ASTM A519: 1018, 1026, 4130, and 4140 (Mechanical grades)

  • ASTM/ASME A106 & SA106: Grades B & C

  • API 5CT: Grades L80 & P110 (Casing and Tubing)

  • NACE MR0175: (Sour Service compliant)

Size Capabilities:

  • Diameter: 1” to 26” OD

  • Wall Thickness: 0.500” to 4” (Heavy Wall specialists)
