Carey Pipe Covering

Product Description

Carey pipe covering was a thermal insulation product manufactured by Philip Carey Manufacturing Company, a Cincinnati-based firm that operated as one of the United States’ oldest and most prominent producers of asbestos-containing building and industrial materials. Philip Carey had roots in the asbestos products industry stretching back to the nineteenth century, and the company built a substantial portion of its commercial identity around asbestos-reinforced insulation, roofing, and construction materials sold to industrial, commercial, and residential markets throughout much of the twentieth century.

Pipe covering, as a product category, served the critical industrial function of controlling heat loss and condensation on piping systems. These systems were found in virtually every type of industrial and commercial facility, including power generation plants, chemical processing facilities, petroleum refineries, shipyards, hospitals, schools, and large residential buildings. Carey pipe covering was designed to wrap around supply and return piping carrying steam, hot water, chilled water, and other process fluids, maintaining operational temperatures and protecting workers and equipment in the surrounding environment. The product was sold in preformed half-shell sections that could be fitted around standard pipe diameters and secured in place, making installation accessible for trades workers in the field.

Philip Carey’s pipe covering line was marketed under the company’s broader asbestos insulation brand portfolio. The company eventually underwent a series of corporate reorganizations and acquisitions. Its successor entities and associated liabilities were absorbed through corporate transitions that ultimately connected Carey’s asbestos product liabilities to the Celotex Corporation and its affiliated trust structure.

Asbestos Content

Carey pipe covering contained asbestos as a primary functional component. Asbestos mineral fibers — most commonly chrysotile, though amphibole varieties including amosite were used in certain industrial-grade formulations — were incorporated into the insulation matrix to provide thermal resistance, structural integrity, and fire protection. Asbestos was uniquely suited to pipe covering applications because of its ability to withstand sustained elevated temperatures without degrading, its resistance to moisture damage, and its capacity to be molded or formed into rigid shapes that retained their insulating properties over years of service.

The asbestos content in industrial-grade pipe covering products of this era was substantial. Preformed sections depended on asbestos fiber to create the interlocked mineral matrix that gave the product its insulating and structural properties. Binders, fillers, and sometimes magnesia were combined with asbestos fiber to produce the final composition, but asbestos remained a dominant ingredient by weight in many formulations.

Because asbestos was central to the product’s performance characteristics, its presence was not incidental. Philip Carey, like other manufacturers operating during this period, sourced asbestos fiber from domestic and international mines and incorporated it throughout their pipe covering product lines as a matter of standard manufacturing practice.

How Workers Were Exposed

Industrial workers across a wide range of trades and job classifications encountered Carey pipe covering during installation, maintenance, repair, and removal activities. Exposure pathways were numerous, and the nature of asbestos fiber release during work with pipe covering products was well-documented over time through industrial hygiene research and litigation.

Installation workers who applied Carey pipe covering to new piping systems were exposed during the cutting, fitting, and trimming of preformed sections. Asbestos-containing pipe covering required cutting to fit around valves, elbows, flanges, and other irregular piping components. Each cut — whether performed with a saw, knife, or other tool — released asbestos dust directly into the worker’s breathing zone.

Maintenance and repair workers faced exposures that were often more intense than those experienced during initial installation. Pipe insulation that had been in service for years or decades frequently became friable — brittle and easily crumbled by hand pressure — making disturbance during maintenance tasks highly likely to release asbestos fibers. Workers who removed old Carey pipe covering to access piping for repairs, or who worked alongside others performing such removals, were exposed to fiber concentrations that industrial hygiene research has documented as potentially significant.

Industrial workers generally in facilities where Carey pipe covering was installed were potentially exposed through the normal deterioration of aging insulation. As pipe covering aged and was subject to vibration, impact, and thermal cycling, surface fibers could be released into the ambient air of the facility. Workers in boiler rooms, mechanical spaces, and process areas where insulated piping was present could accumulate exposure over the course of a career without ever directly handling the insulation product themselves.

OSHA’s current permissible exposure limit for asbestos is 0.1 fibers per cubic centimeter of air as an eight-hour time-weighted average, reflecting the regulatory recognition that no level of asbestos exposure is considered without risk. Pipe covering removal and disturbance activities are specifically addressed under OSHA’s asbestos standards for general industry and construction, which require engineering controls, respiratory protection, and regulated work areas when asbestos-containing insulation is disturbed.

Diseases associated with asbestos exposure from products including pipe covering include mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease. Mesothelioma, a malignant cancer of the lining of the lung or abdomen, is considered a signature asbestos disease with a latency period that can extend for decades following initial exposure.

Individuals who were exposed to Carey pipe covering and subsequently diagnosed with an asbestos-related disease have access to a structured legal remedy through the Celotex Corporation Asbestos Settlement Trust. This trust was established through bankruptcy proceedings involving Celotex Corporation, which held successor liability for asbestos claims connected to Philip Carey Manufacturing Company and its product lines, including Carey pipe covering.

The Celotex Corporation Asbestos Settlement Trust is a Tier 1 trust fund, meaning it is an operative trust with established claims procedures and payment structures for eligible claimants. Carey pipe covering is a documented product within the trust’s claim review framework. Claimants are generally required to demonstrate product exposure and a qualifying asbestos-related disease diagnosis. The trust evaluates claims under defined disease categories that typically include:

  • Mesothelioma
  • Lung cancer (with qualifying exposure and, in some cases, smoking history considerations)
  • Other asbestos-related cancers
  • Asbestosis and severe asbestosis
  • Other asbestos-related nonmalignant conditions meeting defined diagnostic criteria

Filing a claim with the Celotex Trust requires documentation of exposure to Carey pipe covering specifically, along with medical records establishing the diagnosed condition. Occupational history establishing work in facilities or trades where the product was used is central to building an eligible claim.

Workers and family members of workers who were exposed to Carey pipe covering should consult with an asbestos attorney experienced in trust fund claims. Trust fund claims are entirely separate from courtroom litigation and operate under their own procedures and timelines. An attorney familiar with the Celotex Trust’s claim requirements can assist in gathering the exposure documentation, medical records, and occupational history needed to file.
