Proyecto de Primera Revisión del Reglamento Técnico Ecuatoriano PRTE INEN 246 (1R) "Tubos de acero inoxidable" (Draft first revision (1R) of Ecuadorian Technical Regulation PRTE INEN No. 246: "Stainless steel tubing") (10 pages, in Spanish)

The notified Ecuadorian Technical Regulation establishes the requirements to be met by stainless steel tubing, whether with seams (welded) or seamless, both for transporting fluids and for structural use, prior to the marketing of domestic and imported products, with the aim of protecting human health and safety and preventing deceptive practices.

It applies to the following products:

1. Welded stainless steel tubing, of circular cross-section, for mechanical and general engineering purposes.

2. Seamless stainless steel tubing, of circular cross-section, for mechanical and general engineering purposes.

3. Welded stainless steel structural mechanical tubing, of circular, square, rectangular or special-type cross-section:

3.1 Welded stainless steel structural mechanical tubing for use in mechanical applications where appearance, mechanical properties, or corrosion resistance is needed, for structural and ornamental purposes.

3.2 As-welded or cold-reduced structural mechanical tubing in nominal diameter sizes of 406.4 mm (16 inches) outside dimension, and in wall thicknesses of 0.51 mm (0.020 inches) or more.

4. Seamless stainless steel structural mechanical tubing, of circular, square, rectangular or special-type cross-section:

4.1 Seamless stainless steel structural mechanical tubing for use in mechanical applications where resistance to corrosion or high-temperatures is needed.

4.2 Seamless cold-finished structural mechanical tubing and seamless hot-finished structural mechanical tubing in sizes up to 325 mm (12 ¾ inches) in outside nominal diameter (for round tubing).

It does not apply to: 

Steel tubing used in the oil and gas industries.
