Nominal Pipe Size
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. "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 outside diameter). Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched. or Sch., for example – "2-inch diameter pipe, Schedule 40"). NPS is often incorrectly called National Pipe Size, due to confusion with the American standard for pipe threads, " national pipe straight", which also abbreviates as "NPS". The European and international designation equivalent to NPS is ''DN'' (''diamètre nominal''/nominal diameter/Nennweite), in which sizes are measured in millimetres, see ISO 6708.

National Pipe Thread
American National Standard Pipe Thread standards, often called national pipe thread standards for short, are United States national technical standards for screw threads used on threaded pipes and pipe fittings. They include both tapered and straight thread series for various purposes, including rigidity, pressure-tight sealing, or both. The types are named with a full name and an abbreviation, such as NPT, NPS, NPTF, or NPSC. MIP is an abbreviation for male iron pipe, and FIP is an abbreviation for female iron pipe. Outside North America, some US pipe thread sizes are widely used, as well as many British Standard Pipe threads and ISO 7–1, 7–2, 228–1, and 228-2 threads. Types The various types are each named with an abbreviation and a full name, as follows: Uses Threaded pipes can provide an effective seal for pipes transporting liquids, gases, steam, and hydraulic fluid. These threads are now used in materials other than steel and brass, including PTFE, PV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piping
Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of piping design (or piping engineering), though the sensors and automatic controlling devices may alternatively be treated as part of instrumentation and control design. Piping systems are documented in piping and instrumentation diagrams (P&IDs). If necessary, pipes can be cleaned by the tube cleaning process. ''Piping'' sometimes refers to piping design, the detailed specification of the physical piping layo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Dimension Ratio
Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall. Common nominations are SDR11, SDR17, SDR26 and SDR35. Pipes with a lower SDR can withstand higher pressures. SDR=\frac d_o Pipe outside diameter This page lists the standard US nomenclature used in the description of mechanical gear construction and function, together with definitions of the terms.

Copper Tubing
Copper tubing is available in two basic types of tube—plumbing tube and air conditioning/refrigeration (ACR) tube, and in both drawn (hard) and annealed (soft) tempers. Because of its high level of corrosion resistance, it is used for water distribution systems, oil fuel transfer lines, non-flammable medical-gas systems, and as a refrigerant line in HVAC systems. Copper tubing is joined using flare connection, compression connection, pressed connection, or solder. Types Soft copper Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealed to make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing. It can be joined by any of the three methods used for rigid copper, and it is the only type of copper tubing suitable for flare connections. Soft copper is the m ...

British Standard Pipe Thread
British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing piping, pipes and fittings by mating an external (Gender of connectors and fasteners, male) thread with an internal (female) thread. It has been adopted as standard in plumbing and Pipefitter, pipe fitting, except in North America, where national pipe thread, NPT and related threads are used. Types Two types of threads are distinguished: * Parallel (straight) threads, ''British Standard Pipe Parallel thread'' (''BSPP''; originally also known as ''British Standard Pipe Fitting thread''/''BSPF'' and ''British Standard Pipe Mechanical thread''/''BSPM''), which have a constant diameter; denoted by the letter ''G''. * Taper threads, ''British Standard Pipe Taper thread'' (''BSPT''), whose diameter increases or decreases along the length of the thread; denoted by the letter ''R''.

Chlorinated Polyvinyl Chloride
Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling. CPVC, like PVC, is deemed safe for the transport and use of potable water. History Genova Products located in Michigan initially created the first CPVC tubing and fittings for hot- and cold-water distribution systems in the early 1960s. The original tetrahydrofuran (THF) / methyl ethyl ketone (MEK) formulas for CPVC cements were developed by Genova in conjunction with the B.F. Goodrich Company, the original developer of the CPVC resin. Production process Chlorinated polyvinyl chloride (CPVC) is PVC that has been chlorinated via a free radical chlorination reaction. This reaction is typically initiated by application of thermal or UV energy utilizing various approaches. In the process, chlorine ...

Preferred Metric Sizes
Preferred metric sizes are a set of international standards and de facto standards that are designed to make using the metric system easier and simpler, especially in engineering and construction practices. One of the methods used to arrive at these preferred sizes is the use of Preferred number, preferred numbers and Convenient number, convenient numbers, such as the Renard series and 1-2-5 series, to limit the number of different sizes of components needed. One of the largest benefits of such limits is an ensuing multiplicative or exponential reduction in the number of parts, tools and other items needed to support the installation and maintenance of the items built using these techniques. This occurs because eliminating one diameter fastener will typically allow the elimination of a large number of variations on that diameter (multiple thread pitches, multiple lengths, multiple tip types, multiple head types, multiple drive types, and the tools needed for installing each, inclu ...

Fusion Welding
Fusion welding is a generic term for welding processes that rely on melting to join materials of similar compositions and melting points. Due to the high-temperature phase transitions inherent to these processes, a heat-affected zone is created in the material (although some techniques, like beam welding, often minimize this effect by introducing comparatively little heat into the workpiece). In contrast to fusion welding, solid-state welding does not involve the melting of materials. Applications Fusion welding has been a critical factor in the creation of modern civilization due to its vital role in construction practices. Besides bolts and rivets, there are no other practical methods for joining pieces of metal securely. Fusion welding is used in the manufacture of many everyday items, including airplanes, cars, and structures. Beyond construction, a large community uses both arc and flame contact welding to create artwork. Types Electrical Arc Arc welding is on ...

Stubs Iron Wire Gauge
The Birmingham gauge, officially the Birmingham Wire Gauge and often abbreviated as ''G'' or ''ga'', is unit or wire gauge used to measure the thickness or diameter of wires and tubing, including hypodermic needles and other medical tube products. Terminology The Birmingham gauge is also known as the Stubs Iron Wire Gauge or Birmingham Wire Gauge and is distinct from the Stubs Steel Wire Gauge and the British standard gauge, British Standard Wire Gauge. It is commonly referred to simply as ''gauge'' (abbreviated as ''G''), but this should not be confused with the French gauge, a separate system used for measuring the outer diameter of Catheter, catheters. System The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of , to 36, the highest gauge number corresponding to the smallest size of . The increments between gauge sizes are not linear and vary. At higher gauge numbers, the increment between the two highest gauges is , whil ...
