Materials/Specifications

Carbon Steel

Carbon Steel Piping: This piping is an alloy of iron and carbon. Carbon steel exhibits high yield stress, high tensile strength, elasticity, ductility, and lack of brittleness which enable it to operate at high pressures. Carbon steel pipes have greater carrying capacity for a given pressure over pipes made with other materials with the same outer diameter. Carbon steel pipes are supplied in longer lengths than pipes made with other materials, requiring fewer assembly joints. Corrosion is a major disadvantage in carbon steel pipes.

Copper

Copper Piping. This piping is recognized as superior for conveying water. It is light, strong, and corrosion resistant. It does not react with water, has high yield stress, and is germicidal. It is readily available in a multitude of sizes with a broad assortment of fittings. Joints are easily and economically made.

Fiberglass

Fiberglass Piping: Fiberglass pipe is often the material of choice for corrosive process systems. It can withstand higher temperatures and pressures than ordinary thermoplastic materials. Its corrosion and chemical resistance, makes it well-suited for general chemical processing applications. Fiberglass pipe can be used in a wide variety of corrosion resistant conditions. It is 20% lighter than steel, stronger than steel on an equal weight basis, has a coefficient of friction 25% better than steel, has low thermal conductivity, and low long-term maintenance costs.

Gas Poly

Gas Poly Piping. This polyethylene pipe is commonly called gas poly piping because of its nearly exclusive use by the natural gas industry for its distribution lines. This is due to several of its characteristics. It has excellent diffusion resistance. It can be installed with bends over uneven terrain in continuous lengths without additional welds or fittings. It is extremely resistant to scale build up and is impervious to most aggressive chemicals and corrosive elements. Its exceptionally smooth inner surface offers minimal resistance to flow over the life of the pipe. This pipe can be joined by a several methods, but heat fusion is preferred. Polyethylene pipe can also be joined with mechanical and flanged connections.

General

General Piping: A system of pipes used to convey fluids or gases from one location to another. Pipe and fittings can be manufactured from wood, glass, steel, aluminum, plastic, or concrete. In-line components; fittings, valves, meters, and other devices, are used to sense and control the pressure, flow rate, and temperature of the transmitted liquid or gas.

Glass

Glass Piping. This piping, usually manufactured from borosilicate glass, has many desirable characteristics for laboratory applications. It provides long service life, product purity, smooth interior surface, and transparency. It is impervious to almost every corrosive and reagent known, is virtually unaffected by heat and thermal expansion, and does not burn or emit toxic fumes.

Lined

Glass Lined Piping: Glass lining is a form of porcelain enamel, much like the material applied to tubs and sinks for many years. It is applied in a process that forms a permanent chemical and physical bond with the metal surface. The finished surface is extremely smooth and very hard, making glass-lined pipe ideal for transfer of solids or chemicals that tend to adhere to the inside of bare pipe. Using glass-lined pipe significantly reduces maintenance, wasted energy, and repair costs associated with solids build up in piping systems. It is non-permeable; resistant to corrosion, abrasion, high temperatures, and thermal shock; and has a wide pH range

Modular Pneumatic Tubing

Modular Pneumatic Tubing. Modular tubing offers quick mechanical assembly of tubing systems using a complete assortment of tubing segments, fittings, valves, gauges, and ports that are designed to assemble quickly and easily with simple hand tools. Each modular component has a flanged end and includes necessary gasketing and associated clamps to ensure an accurate seal. Most modular systems, available in various materials, provide adapters enabling you to join modular systems to existing system for repairs or quick additions.

Plastic

Plastic Piping: Plastic pipes are lighter than pipes made from other materials. Their smooth inner walls promote high flow rates and resistance to the formation of deposits, preventing clogging. Though they do not have the strength of metal pipes, their flexibility provides them with enough tensile and burst strength to withstand operating pressures encountered in most service conditions. They can withstand external shocks that could cause failure in more brittle materials. They are resistant to water, nearly all acids, alkalis, salt solutions, and other corrosive liquids and gases.

  • SPEC #: 18404
  • Code: 18-40-04

Sanitary

Sanitary Piping: This piping must be non-corrosive and non-reactive with the liquid or materials being transported. Although material selection is important to the design of sanitary piping (glass and stainless steel are commonly used), manufacturing quality is critical. Sanitary piping requires smooth inside surfaces and joint junctions to minimize collection of material on inside surfaces.

  • SPEC #: 18407
  • Code: 18-40-07

Stainless

Stainless Steel Piping: Stainless pipe is a frequent choice for corrosive process systems. Its corrosion and chemical resistance make it well-suited for general chemical processing applications. Its external appearance is suited for installations requiring a clean look. Stainless pipes can be manufactured with highly polished internal surfaces for sanitary applications.
