Domestic acquisitions The company has grown mainly through acquisition of other domestic foundries and related enterprises. In 1926, the company opened its first subsidiary, the Pacific States Cast Iron Pipe Company. Later, McWane acquired Empire Coke Company in 1962, Atlantic States Cast Iron Pipe Company in 1975, and Union Foundry Company in 1977. Between 1984 and 1996, the company continued its expansion with the acquisition of the following companies, M&H Valve Company,
Clow Water Systems, Clow Valve Company, Kennedy Valve Company, Tyler Pipe and Anaco. In 1999, McWane bought two more companies: Manchester Tank & Equipment of
Brentwood, Tennessee and Amerex Corporation of
Trussville, Alabama, expanding its manufacturing of fire extinguishers. In 2008, McWane Poles developed a new product for the
electric utility industry that is used by such companies as the Florida Keys Electric Cooperative. Then, in 2012, McWane entered into the technology industry by adding Synapse Wireless and
Nighthawk, a provider for wireless smart grid solutions.
International expansion McWane's international expansion began in 1989 when it acquired Canada Pipe Company in
Hamilton, Ontario, then part of Canron Inc. of
Toronto. The company established Clow Canada in 1990 with manufacturing in
Saint John, New Brunswick; the Saint John works had previously operated as Thomas McAvity & Company from 1834 to 1960 before being sold to Crane Canada Ltd. Through Canada Pipe, McWane acquired the Bibby Companies in 1997 and in 1999 extended operations to Australia with the acquisition of Manchester Tank & Equipment Company. Through its Amerex subsidiary, McWane also acquired Solberg Scandinavian AS, a
Bergen, Norway-based firefighting foam manufacturer. The company added
Seoul-based Comtech Korea and acquired
UK-based Zinwave in 2014. In 2015, it opened its first manufacturing plant in
Abu Dhabi called McWane Gulf. In June 2024, Manchester Tank & Equipment announced it would acquire the tank refurbishment and recertification business assets of Ditech Testing, a Canadian firm with operations in New Brunswick and Alberta.
China In 2003, in response to increasing pressure to move operations overseas due to competition from importers, McWane filed a petition with the
International Trade Commission asking for relief from Chinese competition. The commission unanimously approved McWane's petition and recommended that President
George W. Bush impose a three-year import quota on China's waterworks fittings and
tariffs of up to 50 percent on imports exceeding the quota. However, in March 2004, President Bush decided not to adopt the commission's recommendation. Following this decision, McWane opted to begin manufacturing its products both domestically and overseas. To that end, in 2005, it opened a plant in China's
Hebei Province. The company was named the "Excellent Environmental Protection Facility of 2006" by the
Cangzhou Environmental Protection Bureau. == Environmental and safety issues ==
