Product Description
Seamless Stainless Steel Stub Ends ASME B16.9
Product Overview

The Seamless Stainless Steel Stub Ends ASME B16.9 are hygienic grade pipe fittings designed for food, beverage and pharmaceutical processing lines. Manufactured from seamless SS304 and SS316L pipe with a mirror polished surface finish, these stub ends provide the smooth, crevice-free surfaces required for sanitary applications.

Because the fittings are seamless, there are no weld seams inside the bore where product could accumulate and breed bacteria. The mirror polished interior with roughness below Ra 0.8 microns allows complete drainage and easy cleaning, meeting the strict hygiene standards of the food industry. Manufactured to ASME B16.9 dimensions, these food grade stub ends pair perfectly with lap joint flanges, enabling fast disassembly for inspection and sanitation.

Frequently Asked Questions
Q1: Why is a seamless fitting better for food processing?

A: Seamless stub ends have no longitudinal weld seam inside the bore, eliminating crevices where food residue and bacteria could accumulate. This makes cleaning and sanitation much more effective.

Q2: What surface roughness can you achieve?

A: Our standard hygienic finish is mirror polished with surface roughness below Ra 0.8 microns. Finer finishes such as Ra 0.4 microns can be provided for pharmaceutical applications.

Q3: Is SS304 suitable for food contact?

A: Yes, SS304 is FDA compliant and widely used in food processing. For acidic or chloride containing food products, SS316L provides better corrosion resistance and is recommended.

Q4: Can these fittings be cleaned with CIP systems?

A: Yes. The smooth mirror polished bore and seamless construction make these stub ends fully compatible with clean in place systems, allowing effective cleaning without disassembly of the pipeline.
