From Filter to FlangeMetal pipe, fittings, flanges, valves, & engineered products

You already count on CFS for strainers, housings, and filtration media. Now you can source the metal piping that connects it all — carbon steel, stainless, and alloy, from approved mills with complete traceability.

Why source metals through CFS?

One order. One source. One less vendor to manage.

Adding a metals supplier means another account, another PO, and another set of lead times to track. When you source metals alongside your filtration through CFS, you simplify the job without giving up quality.

01
Qualified mills onlyEvery pipe, fitting, and flange we stock comes from manufacturers that have passed a formal qualification process.
02
Verified to specEach product is tied to a documented Purchase Product Specification — no guesswork, no substitutions.
03
Complete traceabilityFull material records from mill to your dock, so you have the paper trail your projects and audits demand.

What we stock

Metal PVF & engineered products

The ranges below are representative of what we keep on the shelf. If your project calls for something outside these specs, ask — we can source it.

Pipe

Carbon, stainless & nickel alloy

Seamless and welded pipe in the sizes and schedules your projects demand. Whether you're tying into a filtration skid or running a new header, the pipe is sourced from approved mills and ships with full MTRs.

CarbonSeamless & welded, 1/2"–24", A106 / A333 Gr. 6 / API 5L X42
StainlessWelded & seamless, 1/2"–16", 304/304L / 316/316L / 347H
AlloySeamless nickel alloy (Monel 400), 1/2"–8"
ScheduleSTD through XXH, including S80, S120, S160

Butt Weld Fittings

Elbows, tees, reducers & caps

The direction-changers and branches that route process media where it needs to go. We carry carbon, high-yield, and stainless fittings across a wide range of sizes and wall thicknesses.

CarbonSeamless, 1/2"–36", A234 WPB / A420 WPL6
High yield2"–24", WPHY 52 / WPHY 65

Flanges

Carbon, stainless, alloy, & specialty

The connection point between your pipe and your equipment. A deep selection of carbon, stainless, low-chrome, high-yield, and nickel alloy flanges, ready to match whatever your piping spec calls for.

Carbon1/2"–36", 150# through 2500#, A105N / A350 LF2
Stainless1/2"–16", 150#–2500#, 304/304L / 316/316L / Alloy 20
SpecialtyLow R.E. (HF), high yield (F52/F65), low chrome (F5/F9/F11)
NickelAlloy 400 (Monel), 1/2"–8", 300# / 600#

Valves & Automation

Pipeline, terminal, & process applications

CFS already carries ball, check, butterfly, and pressure-reducing valves for filtration systems. Our metals line extends that to heavy-duty pipeline and process valves with electric and pneumatic actuation packages.

ActuationElectric & pneumatic; quarter-turn, multi-turn, linear
TypesAPI 6D ball, gate, check, triple offset, metal-seated, cryogenic
MarketsLiquid & gas pipelines, terminals, refining, chemical, power

Engineered Products

Terminal, storage, & loading-rack equipment

Specialized hardware for liquid terminal and pipeline operations — presets, loading arms, overfill protection, tank gauging, and flame arrestors. The equipment that sits between your storage and your truck.

Load rackPresets, loading arms, API couplers, grounding & overfill systems
ValvesIsolation & ESD, strainers, DBB plug valves, slab & expanding gate
StorageAPI-6D valves, tank gauging, flame arrestors, water draw valves
