    A135 Grade A & B Tubing

    Valmont  Tubing produces round electric resistance welded (ERW) steel tubing to meet ASTM specifications A135 Grade A and Grade B that is often used in the  conveying of gas, vapor, water or other liquids.  Valmont  produces pipe and tubing sizes up to 12" NPS (12.75" OD) and in wall thicknesses up to 0.312" nominal that meet the  requirements called out for in A135. Beginning in early 2016, Valmont  will begin producing schedule 10 light-weight fire sprinkler pipe in the 4" NPS (4.50" OD) to 8" NPS (8.625"OD) size range that meets ASTM A135. Please click on our Tubing Vs. Pipe comparison page that lists standard pipe  sizes and the equivalent tubing OD size and gauges produced by Valmont. 

    For a complete listing of all tubing sizes produced by Valmont, please visit our Steel Tubing Product Catalog. For more information about our new fire protection sprinkler pipe, please visit our Fire Sprinkler Pipe Sizes page.

    Specification Notes

    *Chemical,  physical, flattening, and hydrostatic testing or eddy current testing is required to meet ASTM A135  while a transverse tensile test is required only for sizes 8.625" OD and larger. As a standard, Valmont will produce fire sprinkler pipe using the eddy current testing (NH) alternative to hydro testing.

    *If  testing requirements differ from A135 Grade A or Grade B requirements listed above, please note at time of inquiry and order placement.

    *For more detailed information on the A135 specification and to purchase a copy of it, please visit the ASTM website.

    Please contact one of our knowledgeable sales staff members who will assist you with any further questions regarding this specification or with your  specific tubing requirements.
