Lined Pipe in South Carolina
From the tire plants of the Upstate to the chemical campus on the Cooper River, South Carolina makes things that need acid, caustic and solvent piping that will not corrode. Marspec Technical Products fabricates PTFE-, PVDF- and polypropylene-lined steel pipe spools and fittings and supplies lined valves, piping accessories and temperature-maintenance products for exactly those lines. Call (251) 625-4949 or contact us online and tell us what you are moving.
We have spent more than half a century in plastic-lined piping, working from Fairhope, Alabama, and shipping nationwide. South Carolina is a short haul for us, and its mix of paper, chemical and manufacturing work is one we know well.
South Carolina's process industries, region by region
Lowcountry: the Cooper River chemical corridor
Berkeley County's Bushy Park is a 1,530-acre chemical manufacturing campus near the Port of Charleston, with shared utilities and rail and water access, and its plants and the specialty and pine-chemical producers around North Charleston run their own acid, caustic, solvent and resin streams. The steel mill at Huger pickles coil in hydrochloric acid and regenerates it, and Redwood's battery-recycling plant in Berkeley County recovers lithium, nickel, cobalt and copper by hydrometallurgy. Every one of those streams is a textbook case for PTFE-lined pipe, which handles the acid, caustic and solvent streams, HCl pickle liquor and acid leach solutions inside a carbon steel housing; PVDF suits the acid streams but not the caustic or the ketone, ester and amine solvents.
Midlands, Pee Dee and Upstate: paper, tires and textiles
In the Midlands and Pee Dee, the kraft mills at Eastover and Bennettsville run bleach plants on chlorine dioxide, sodium chlorate, caustic, peroxide and sulfuric acid. The state is also the country's leading tire producer, turning out more than 99,000 tires a day across plants in Greenville, Spartanburg and Anderson counties in the Upstate and Aiken, Sumter and Chester counties elsewhere in the state and accounting for roughly a third of United States tire exports. Tire cord is brass-plated and pickled in sulfuric acid and copper and zinc sulfate baths, and compounding and cement areas handle solvents and process oils. The Upstate's remaining textile finishers mercerize in caustic and bleach with peroxide and hypochlorite.
What we supply to South Carolina plants
For acid, solvent and chlorine dioxide lines: custom lined pipe spools and fittings, 1/2" through 12", PTFE-lined, or PVDF- or polypropylene-lined where a specification calls for them, in carbon steel or 304/316 stainless housings, fabricated to your isometrics in lengths up to 20 ft; polypropylene is not suitable for aromatic or chlorinated solvents. Elbows, tees, crosses, laterals, reducers, reducing flanges and instrument tees are built to the same liner specification. Hydrocarbon solvents can build a static charge that pinholes a plain lining or ignites vapor, so bond and ground the spools and use anti-static PFA-AS valves; tell us if your specification calls for an anti-static liner.
For shutoff, throttling and sampling: lined ball, plug, butterfly, diaphragm, check and sampling valves, with PFA linings on the ball, plug and diaphragm valves and a PTFE lining on the butterfly valve. For the rest of the line: lined strainers, expansion joints, spacers, spectacle blinds, sight glasses and solid PTFE pipe from our piping accessories range.
For lines that freeze, crystallize or thicken: jacketed lined pipe, clamp-on steam heaters, electric tracing and heat-transfer compound. Fifty percent caustic crystallizes at roughly 54 °F (12 °C), and the Upstate sees nights well below that, so a traced caustic header at a mill or chemical plant is cheap insurance against a plugged line in January. For jacketed or traced service, we recommend specifying PTFE. Dimensional data, liner thicknesses and torque tables are on our Technical Details page.
Quality you can write into the spec
Our lined pipe and fittings comply with ASTM F1545. Fittings conform dimensionally to ANSI B16.5 and are welded to ASME B31.3 by welders certified to ASME Section IX, and every lined spool and fitting gets a minimum 10,000-volt spark test to catch liner defects before they reach a pickling line or a bleach plant.
Serving Charleston, Columbia, Greenville and the rest of the state
We ship to Charleston, North Charleston, Goose Creek, Moncks Corner, Summerville, Columbia, Aiken, Orangeburg, Florence, Hartsville, Rock Hill, Greenville, Spartanburg, Anderson, Greenwood and Seneca. Send us a spool list, a valve takeoff or the line you cannot keep steel in, and we will quote custom spools and valves to match. Call (251) 625-4949 or contact us online.
FAQ: Lined Pipe in South Carolina
Which liner suits chlorine dioxide and bleach plant service at a Midlands or Pee Dee kraft mill?
PTFE for chlorine dioxide, chlorate and hot caustic, and for the cooler caustic, filtrate and hypochlorite lines on the same liner specification; polypropylene is available for cooler caustic and alkaline filtrate where a specification calls for it. Lined plug and butterfly valves handle the isolation; on hypochlorite, use lined diaphragm valves, or ball valves with a vented ball (vent facing upstream).
Can lined pipe handle sulfuric acid leach and pickle liquor at a Lowcountry steel or battery-recycling plant?
It can. PTFE handles sulfuric acid across the concentration range and hydrochloric pickle liquor, PVDF the dilute leach strengths (not hot concentrated acid or oleum), and the smooth liner resists scaling. Tell us the temperature and solids loading and we will size the spools and valves.
How does ordering work for a plant in Charleston or Greenville?
Send drawings, a line list or even a photo of the failed section. We quote from Fairhope, Alabama, build custom spools to your dimensions, spark test them and ship nationwide.
