Lined Pipe in Massachusetts

Massachusetts runs on fluids that eat steel. Biologics plants along I-495 clean with hot caustic and phosphoric acid, wafer fabs in Wilmington and Lowell etch with hydrofluoric and sulfuric acid, plating shops from Attleboro to Worcester pump chromic and nitric acid, and Deer Island doses sodium hypochlorite around the clock. Marspec Technical Products fabricates the plastic-lined pipe spools and supplies the lined fittings and valves that carry those media without corrosion or contamination, with spools shipped from Fairhope, Alabama.

If you are specifying a new line or replacing one that failed, call us at (251) 625-4949 or contact us online with your sizes, pressures and media. We quote custom spools from a sketch or an isometric.

Industries in Massachusetts that run on lined pipe

Massachusetts has no refineries and no chlor-alkali plants. What it has is the largest life sciences cluster in the country, a compact but busy semiconductor base, more than a hundred metal finishing shops, and some of the largest water infrastructure in the Northeast, all moving acids, caustics, oxidizers or ultra-pure water that carbon steel cannot handle.

Biomanufacturing and pharmaceuticals

The biomanufacturing build-out that began in Cambridge has pushed outward along Route 128 and I-495: cell therapy and biologics production at Devens, clinical manufacturing in Andover and Billerica, drug substance plants in Framingham, Norwood and Lexington, and a growing cluster around Worcester, now among the top fifteen life sciences hubs in the country. These plants run clean-in-place systems that push sodium hydroxide, phosphoric and nitric acid through the headers serving bioreactors and chromatography skids, and buffer preparation handles concentrated acids and bases by the tote. PTFE-lined pipe keeps iron, chromium and nickel out of the process, tolerates the full pH swing of a CIP cycle, and does not pit under chloride buffers the way 316L can. Lined diaphragm valves give a drainable shutoff on the chemical side of the plant.

Semiconductors and electronics

Massachusetts fabs are smaller than those in Arizona and no gentler on piping. Analog and MEMS devices come out of Wilmington, and gallium arsenide and gallium nitride RF chips out of Lowell, where a multi-year upgrade is adding 150 mm gallium-nitride-on-silicon-carbide capacity. Wet benches consume hydrofluoric, sulfuric, nitric and phosphoric acid, hydrogen peroxide and ammonium hydroxide, and the acid waste and fluoride treatment systems downstream run on lime slurry, calcium chloride and caustic. PVDF-lined pipe handles the acids at ambient temperature, but hot concentrated sulfuric acid goes in PTFE, and PTFE-lined spools and lined plug valves serve mixed acid waste headers whose composition changes shift to shift, with heavy-wall liners and vented housings where HF or HCl is present.

Metal finishing, plating and specialty chemicals

More than a hundred plating and metal treating shops operate in the state, concentrated in Middlesex, Essex and Norfolk counties and serving aerospace, defense electronics, medical devices and the Attleboro jewelry trade. Their lines move chromic acid, nitric and hydrochloric pickles, sulfuric anodizing baths and cyanide rinses, and their waste treatment rooms meter hypochlorite for cyanide destruction and bisulfite for chrome reduction. A chromatography media plant in Taunton's Myles Standish Industrial Park and the specialty paper mills of the Berkshires, including the Dalton mill that makes currency paper, add solvents and bleaching agents. PTFE-lined pipe takes the ambient acid and caustic transfer lines along with the hot and mixed services; polypropylene-lined pipe is available for ambient transfer where a specification calls for it, except on nitric and chromic acid and hypochlorite.

Water, wastewater and power

Deer Island is the second-largest wastewater plant in the United States, treating roughly 380 million gallons a day on average and up to 1.2 billion at peak, disinfecting with sodium hypochlorite and dechlorinating with sodium bisulfite. Municipal plants from Springfield to Fall River use the same chemistry plus ferric chloride and alum for phosphorus removal, and gas-fired generators such as the Canal plant on Cape Cod Canal regenerate demineralizers with sulfuric acid and caustic. Bulk hypochlorite releases oxygen as it degrades, so vented lined lines with lined ball or diaphragm valves outlast steel.

What we supply to Massachusetts plants

Custom lined pipe spools from 1/2" through 12", lined with PTFE, PVDF or polypropylene inside carbon steel or 304/316 stainless housings, fabricated to your drawings in lengths up to 20 ft. Our lined pipe and fittings, elbows, tees, reducers and flanges, conform dimensionally to ANSI B16.5 and bolt straight up to existing flanged equipment.

Lined valves: ball, plug, butterfly, diaphragm, check and sampling valves with PTFE or PFA wetted parts, faced to match the spools.

Piping accessories and temperature maintenance: lined strainers, expansion joints, spacers, spectacle blinds, sight glasses and solid PTFE pipe, plus clamp-on steam heaters, electric tracing and heat-transfer compound. In a Massachusetts winter, 50 percent caustic begins to crystallize near 54 degrees F and outdoor hypochlorite lines thicken; tracing matched to the liner's temperature limit keeps the line in service.

Built to the standards your spec calls for

Our lined pipe and fittings comply with ASTM F1545. Lined fittings are welded to ASME B31.3 by welders certified to ASME Section IX, and every lined pipe spool and fitting receives a minimum 10,000-volt spark test before it ships. We have been in plastic-lined piping for more than half a century; liner temperature and vacuum ratings are on our Technical Details page.

Serving Boston, Worcester, Springfield and the SouthCoast

We ship nationwide from Fairhope, Alabama, to Boston and Cambridge, the Route 128 and I-495 corridors through Waltham, Andover, Billerica, Lowell, Marlborough and Devens, Worcester, Springfield and the Pioneer Valley, Pittsfield and the Berkshires, and Taunton, Fall River and New Bedford on the SouthCoast. Call (251) 625-4949 or contact us online and tell us what the line will carry and where it runs.

FAQ: Lined Pipe in Massachusetts

Can lined pipe meet the material requirements of a Massachusetts biomanufacturing CIP system?

Yes. PTFE pipe liners and PFA valve liners resist the sodium hydroxide, phosphoric acid and nitric acid used in CIP, add no extractable metals, and are rated for the temperatures used on the chemical side of the plant. We supply lined diaphragm valves for drainable shutoff; product-contact lines that your spec requires in sanitary stainless tube stay stainless.

Which liner do you recommend for acid waste systems at the fabs in Wilmington or Lowell?

PTFE for hot, concentrated sulfuric or nitric acid and peroxide mixes and for hydrofluoric acid and mixed acid waste headers whose composition changes, with heavy-wall liners and vented housings on HF lines; PVDF for the same acids dilute or at ambient temperature. Send us the chemistry and we will confirm the liner before you order.

Is PTFE-lined pipe suitable for the sodium hypochlorite service used at plants like Deer Island?

Yes. Hypochlorite at 12.5 percent corrodes steel and pits stainless, while a PTFE liner is unaffected. Spools should be vented at high points because hypochlorite releases oxygen as it degrades in storage.

Do you heat trace lined pipe for outdoor caustic lines in a New England winter?

Yes. We supply clamp-on steam heaters, electric tracing and heat-transfer compound matched to the liner's temperature limit, so 50 percent caustic stays above its crystallization point without damaging the liner.
