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 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 and oxidizers that carbon steel cannot handle, and caustics and ultra-pure water it must not touch.
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 cluster around Worcester. 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. 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 is an option only on cooler, dilute acid; 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.
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. The specialty paper mills of the Berkshires, including the Dalton mill that makes currency paper, add 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, but it is not suitable for strong nitric acid, which stays in PTFE.
Water, wastewater and power
Deer Island is one of the largest wastewater plants 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 lined lines, fitted with lined diaphragm valves or ball valves with a vented ball (vent facing upstream), 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 (12 degrees C), and tracing matched to the liner's temperature limit keeps the line in service. For jacketed or traced service, we recommend specifying PTFE. Hypochlorite can freeze in deep cold; trace it only to keep it from freezing, and never overheat it, since heat speeds its decay.
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 limits, liner thicknesses, flange dimensions and torque tables 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 concentrated sulfuric or nitric acid and peroxide mixes and for hydrofluoric acid and mixed acid waste headers whose composition changes; PVDF an option only on the same acids cooler and dilute. 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. Lines 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. For jacketed or traced service, we recommend specifying PTFE.
