Product Description

ASME SA 333 Grade 6 Specification covers nominal (average) wallSeamless and Welded carbon and Alloy Steel pipe intended for low temperature use. Several grades of ferritic steel are included like grade1, grade3 & grade6. Some product sizes may not be available under ASME SA 333 Grade 6 Carbon Steel Seamless Pipes because heavier wall thicknesses have an adverse effect on low-temperature impact properties. ASME SA 333 Grade 6 Pipes are supplied with NACE MR 0103 AND NACE MR 0175 certifications with additions of HIC testing at low temperatures.

Product Identification

In addition to the marking specified in Specification A 999/A 999M, the marking should have the length, an additional symbol -S-, if ASME SA 333 Grade 6 Carbon Steel Seamless Pipes conforms to any of the Supplementary Requirements S1 to S6, the schedule number of the pipe is ordered to a schedule number viz. SCH 5,10,20,30,40,60,80,100,120,140,160,XS, XXS, STD, and the heat number of or manufacturer-s number by which the heat can be identified as per ASME SA 333 Grade 6.

Permissable Variations

Wall Thickness : the minimum wall thickness at any point or end on ASME SA 333 Pipes and Tubes shall not be greater than 12.5% under the nominal thickness specified. Inner Diameter: for pipe ordered in inside diameter, the inside diameter shall not vary more than ñ 1% from the required/specified inside diameter.

Inspection Certification

The Manufacturer shall provide Material Test certificate of inspection to the purchaser stating that the material has been manufactured, sampled, tested, and inspected in accordance with ASME SA 333 Grade 6( including year of issue), and has satisfied all the requirements of ASME SA 333.
