One-Minute Overview

ASTM TP316 welded pipe, 1/8 to 30 inch, STD wall, 5.8 m plain end lengths.
Molybdenum bearing 316 stainless for chlorides, brine and marine exposure.
Corrosion resistant from instrument bore up to 30 inch process mains.
End caps on both ends; seam tested and lengths checked before dispatch.

TP316 is the stainless grade you reach for when 304 is not enough. The molybdenum addition shifts the pitting resistance upward, which matters whenever chlorides are present — brackish water, cleaning chemicals, coastal air, marine washdown. This A312 welded pipe runs that grade across a wide size band, 1/8 to 30 inch in standard wall with 5.8 m plain end lengths, so the same corrosion logic can follow a project from an instrument line to a 30 inch process main without switching materials mid-drawing.

Specifying 316 is really a question about the medium. Ask what the line carries, how often it sits wet, and whether chlorides concentrate under deposits or in crevices — that last case is where pitting starts, and molybdenum is what buys time. The 5.8 m length is the container-friendly format that keeps freight efficient on export orders while still limiting field joints on site. Weld with a matching 316 consumable, keep heat input moderate, and preserve the passive layer: no carbon steel brushes, no grinding discs shared with carbon work, and passivation where the service warrants it. In severe chloride duty, talk to us about duplex stainless as the next step.

Installation and handling follow stainless discipline at every size: caps on until fit-up, bundles supported and separated, ends clean for welding. Size and wall thickness are confirmed per inquiry, and a detailed specification sheet is available on request.

FAQ

Q1. When should I choose TP316 over TP304?

When chlorides are part of the story. Seawater proximity, brine, chloride-bearing cleaning agents and coastal atmospheres all push the case toward 316, because molybdenum raises resistance to pitting and crevice corrosion. For dry or mild service, 304 remains the economical choice.

Q2. Why is the length 5.8 m instead of 6 m?

5.8 m is the export-friendly length that loads efficiently in containers, which keeps freight sensible on international orders. On site the difference is small — one fewer or one extra field joint depending on the run — and the cut list is planned from the spool drawing anyway.

Q3. What is the next step if 316 is not enough?

For truly severe chloride duty, duplex stainless steels combine higher strength with better chloride resistance, at the cost of tighter fabrication control. Tell us the medium, temperature and concentration and we will confirm with you whether 316 holds or a duplex grade is the better answer.

Q4. What is the minimum order for TP316 pipe?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Kits made to your drawing or for a non-standard bolt pattern are quoted individually, because the minimum really depends on the material and the tooling involved.
