Nooter Pressure Vessels and Storage Tanks

Product Description

Nooter Corporation, headquartered in St. Louis, Missouri, was a prominent American manufacturer of industrial pressure vessels, storage tanks, heat exchangers, and related process equipment. Founded in the late nineteenth century, the company built a long-standing reputation as a supplier to the petrochemical, refining, power generation, and chemical processing industries. Nooter’s fabricated equipment was installed across a wide range of heavy industrial facilities, including oil refineries, chemical plants, pulp and paper mills, power stations, and manufacturing complexes throughout the United States and internationally.

Pressure vessels and storage tanks manufactured by Nooter were engineered to contain gases, liquids, and chemical compounds under conditions of elevated pressure and extreme temperature. These vessels were custom-fabricated to meet the demanding specifications of individual industrial clients, meaning that Nooter equipment was found in highly varied configurations across many different facility types. The company’s products were considered industrial staples during the mid-twentieth century, a period when asbestos was routinely incorporated into industrial equipment and the insulation systems surrounding it.

Nooter Corporation continued operating through significant portions of the twentieth century before facing mounting asbestos-related litigation that became central to its legal history. The company’s pressure vessels and storage tanks remain a documented subject of asbestos exposure claims brought by workers who were present during manufacturing, installation, maintenance, and repair of this equipment.


Asbestos Content

The asbestos content associated with Nooter pressure vessels and storage tanks is primarily documented through the context of insulation systems and ancillary materials applied to the equipment rather than through asbestos embedded uniformly in the vessel walls themselves. Pressure vessels and storage tanks operating at high temperatures required substantial thermal insulation to maintain process temperatures, protect workers from surface heat, and comply with engineering specifications. During the mid-twentieth century, asbestos-containing insulation materials — including block insulation, blanket insulation, pipe covering, and finishing cements — were standard components of these insulation systems.

Litigation records document that asbestos-containing materials were applied to and around Nooter-manufactured vessels and tanks during fabrication, field installation, and subsequent maintenance activities. Plaintiffs alleged that the vessels as installed and maintained incorporated asbestos insulation products that were either selected by Nooter, specified in engineering documentation, or supplied alongside the primary equipment. Additionally, gaskets, packing materials, and other sealing components used in connection with pressure vessel fittings, flanges, and nozzles were alleged to have contained asbestos during the relevant manufacturing periods.

Because Nooter produced custom equipment across several decades, the specific asbestos-containing materials associated with any individual vessel or tank may vary depending on the year of fabrication, the facility where the equipment was installed, and the maintenance history of that particular piece of equipment. Documentation from litigation proceedings has addressed these variations on a case-by-case basis.


How Workers Were Exposed

Workers exposed to asbestos in connection with Nooter pressure vessels and storage tanks encompassed a broad population of industrial employees who encountered this equipment across its full lifecycle — from initial fabrication through decades of operation and periodic maintenance.

Fabrication and Shop Workers: Litigation records document that workers employed at Nooter’s manufacturing facilities and at subcontracted fabrication shops were potentially exposed to asbestos during the production process. Applying asbestos-containing insulation, cutting insulation materials to fit vessel contours, and finishing insulated surfaces were tasks that could generate airborne asbestos fibers in enclosed shop environments.

Insulators and Pipefitters: Field insulators and pipefitters who installed thermal insulation systems on Nooter vessels at industrial plants were among the workers most directly exposed. Plaintiffs alleged that cutting, fitting, and securing asbestos insulation blocks or blankets around large vessels released substantial quantities of respirable asbestos fibers. This work frequently occurred in confined or semi-enclosed spaces where fiber concentrations could accumulate.

Boilermakers and Vessel Maintenance Workers: Workers tasked with maintaining or repairing pressure vessels — including inspecting internal surfaces, replacing gaskets and packing, and performing welding or mechanical work on fittings — alleged exposure when they disturbed asbestos insulation to gain access to vessel components. Maintenance work often required removing and replacing insulation materials that had hardened, fractured, or deteriorated over years of service, conditions that litigation records document as particularly hazardous in terms of fiber release.

Refinery and Chemical Plant Operators: General industrial workers employed at facilities where Nooter vessels were in operation could be exposed to asbestos fibers released during routine maintenance activities performed by contractors or in-house maintenance crews working in the same areas. Plaintiffs alleged that ambient fiber levels in areas surrounding active insulation work could reach concentrations posing health risks to nearby workers not directly performing the insulation tasks.

Millwrights and General Industrial Tradespeople: Millwrights and other tradespeople involved in rigging, positioning, or mechanically connecting Nooter vessels during installation were alleged to have worked in proximity to ongoing insulation application, creating secondary exposure pathways.

The diseases documented in litigation involving Nooter pressure vessel exposure include mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease. These conditions typically present with latency periods of ten to fifty years following initial asbestos exposure, meaning that workers employed in industrial settings decades ago may only now be receiving diagnoses connected to this equipment.


Nooter Corporation has been named as a defendant in asbestos personal injury litigation across multiple jurisdictions in the United States. Litigation records document that numerous plaintiffs — primarily industrial workers and their surviving family members — have brought claims alleging that asbestos exposure connected to Nooter pressure vessels and storage tanks caused serious and fatal diseases.

Tier 2 — Active Litigation: Because Nooter Corporation does not have an established asbestos bankruptcy trust fund in the manner of some other historical asbestos defendants, claims involving Nooter equipment are pursued primarily through the civil litigation system. Plaintiffs alleged negligence, failure to warn, product liability, and related claims against Nooter Corporation and, where applicable, against manufacturers of the asbestos-containing insulation and component materials used in conjunction with Nooter vessels. Litigation records document that claims have proceeded in state and federal courts, with outcomes varying based on jurisdiction, evidence of product identification, and documented exposure history.

Co-Defendant and Multi-Party Claims: Because asbestos exposure in industrial settings typically involved products from multiple manufacturers, plaintiffs in Nooter-related cases have frequently pursued simultaneous claims against insulation manufacturers, gasket suppliers, and other defendants whose products were used in the same work environments. Several of those co-defendants have established asbestos bankruptcy trust funds through which separate claims may be filed in parallel with civil litigation against solvent defendants.

Who Should Seek Legal Counsel: Individuals diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease who worked in industrial settings where Nooter pressure vessels or storage tanks were present — whether as direct fabrication workers, insulators, maintenance personnel, or general plant workers — should consult an attorney experienced in asbestos litigation. Legal counsel can assist in identifying all potentially liable parties, locating historical employment and product identification records, and pursuing all available legal remedies within applicable statutes of limitations.
