The industry then shifted to more durable asbestos cement pipe. [ 1 ] While a variety of companies competed with Fiber Conduit Co., including American (East Chicago, Indiana), J–M Fibre Conduit (Lockport, New York), Bermico (Brown Co. of Berlin, New Hampshire), and American (Fulton, New York), it was by far and away the industry leader in ...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Asbestos cement competed with aluminum alloy, available in large quantities after WWII, and the reemergence of wood clapboard and vinyl siding in the mid to late 20th century. Asbestos cement is usually formed into flat or corrugated sheets or into pipes, but can be molded into any shape that can be formed using wet cement.

Transite originated as a brand that Johns Manville, an American company, created in 1929 for a line of asbestos-cement products, including boards and pipes. [1] In time it became a generic term for other companies' similar asbestos-cement products, and later an even more generic term for a hard, fireproof composite material , fibre cement ...
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
Gravity sewers have been assembled from cast iron pipe, vitrified clay pipe, precast concrete pipe, asbestos-cement pipe, and plastic pipe. [8] While some older brickwork sewers remain in use, new sewers of diameters exceeding 1 metre (39 in) typically use reinforced concrete.
Japan has its own set of standard pipe sizes, often called JIS pipe. The Iron pipe size (IPS) is an older system still used by some manufacturers and legacy drawings and equipment. The IPS number is the same as the NPS number, but the schedules were limited to Standard Wall (STD), Extra Strong (XS), and Double Extra Strong (XXS).
