The energy consumed in manufacturing ductile iron pipe was 19.55 MJ per kg and volume of emissions released during manufacture was 1.430 kg CO 2 per kg, compared to 68.30 MJ per kg of energy and 4.860 kg CO 2 per kg emissions for PVC pipes, and 1.24 MJ per kg and 0.148 kg CO 2 per kg for concrete pipes of the same diameter.
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 ...
Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
The material with which a pipe is manufactured often forms as the basis for choosing any pipe. Materials that are used for manufacturing pipes include: Carbon steel; ASTM A252 Spec Grade 1, Grade 2, Grade 3 Steel Pile Pipe; Plastic piping, e.g. HDPE pipe, PE-X pipe, PP-R pipe or LDPE pipe. [11] Low temperature service carbon steel; Stainless steel
Fe-Cr-Ni-C grades. Some carbon is replaced by nickel. They offer higher toughness and higher corrosion resistance. Representative grades include Type 431. Martensitic precipitation hardening grades. 17-4 PH (UNS S17400), the best-known grade, combines martensitic hardening and precipitation hardening to increase strength and toughness.
E.g.: API 5L Grade B – now ISO L245 where the number indicates yield strength in MPa; ASME SA106 Grade B (Seamless carbon steel pipe for high temperature service) ASTM A312 (Seamless and welded austenitic stainless steel pipe) ASTM C76 (Concrete Pipe) ASTM D3033/3034 (PVC Pipe) ASTM D2239 (Polyethylene Pipe) ISO 14692 (Petroleum and natural ...
Cast iron pipes piled up near the construction site. Cast iron pipe is pipe made predominantly from gray cast iron.It was historically used as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 17th, 18th, 19th and 20th centuries.
