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''. These can be combined into two types of joints: ; Jointing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical Standard
A technical standard is an established Social norm, norm or requirement for a repeatable technical task which is applied to a common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices. A technical standard includes definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength. It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes, and practices. In contrast, a custom, convention, company product, corporate standard, and so forth that becomes generally accepted and dominant is often called a ''de facto'' standar ...

British Standard Brass Thread
British Standard Brass or British Brass Thread is an imperial unit based screw thread. It adopts the Whitworth thread form with a pitch of 26 threads per inch and a thread angle of 55 degrees for all diameters. It is often wrongly called ''British Standard Brass'' but is not actually covered by a British Standard. The reason for adopting 26 tpi, is brass tube has a relatively similar wall thickness irrespective of the outside diameter of the tube, therefore as BSW thread depths are determined by the threads per inch, a lower tpi would reduce the strength of the tube or cut right through it. Brass tube threads can be confused with the British Standard Cycle thread, one of which that is most common is also 26 tpi. The difference being the thread angle of the British Standard Cycle is the same as the metric thread angle of 60 degrees. Nominal sizes are usually in the range to 2 inches.

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] |

ISO 8
The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and () it has published over 25,000 international standards covering almost all aspects of technology and manufacturing. It has over 800 technical committees (TCs) and subcommittees (SCs) to take care of standards development. The organization develops and publishes international standards in technical and nontechnical fields, including everything from manufactured products and technology to food safety, transport, IT, agriculture, and healthcare. More specialized topics like electrical and electronic engineering are instead handled by the International Electrotechnical Commission.Editors of Encyclopedia Britannica. 3 June 2021.Internatio ...

ISO 6
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system introduced in 1974. A closely related system, also known as ISO, is used to describe the relationship between exposure and output image lightness in digital cameras. Prior to ISO, the most common systems were ASA in the United States and DIN in Europe. The term ''speed'' comes from the early days of photography. Photographic emulsions that were more sensitive to light needed less time to generate an acceptable image and thus a complete exposure could be finished faster, with the subjects having to hold still for a shorter length of time. Emulsions that were less sensitive were deemed "slower" as the time to complete an exposure was much longer and often usable only for still life photography. Exposure times for photographic emulsions shortened from hours to fractions of a second by the late 19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threaded Pipe
A threaded pipe is a pipe with screw-threaded ends for assembly. Tapered threads The threaded pipes used in some plumbing installations for the delivery of gases or liquids under pressure have a tapered thread that is slightly conical (in contrast to the parallel sided cylindrical section commonly found on bolts and leadscrews). The seal provided by a threaded pipe joint depends upon multiple factors: the labyrinth seal created by the threads; a positive seal between the threads created by thread deformation when they are tightened to the proper torque; and sometimes on the presence of a sealing coating, such as thread seal tape or a liquid or paste pipe sealant such as pipe dope. Tapered thread joints typically do not include a gasket. Especially precise threads are known as "dry fit" or "dry seal" and require no sealant for a gas-tight seal. Such threads are needed where the sealant would contaminate or react with the media inside the piping, e.g., oxygen service. Ta ...

Panzergewinde
The Stahlpanzerrohrgewinde (, "steel conduit thread") standard for screw threads, more often called by the shortened Panzergewinde (), was a technical standard created in Germany and subsequently used in Switzerland, Austria, and other neighboring European countries. It has been retracted. The thread is used to join pieces of electrical conduit and cable glands. Alternative stylings of the German name are ''Stahl-Panzer-Rohr-Gewinde'', an abbreviated form ''StaPa-Rohr-Gewinde'', and the acronym ''PG''. Overview The standard, codified by the ''Deutsches Institut für Normung'' (DIN, German Institute for Standardization), is DIN 40430. ''Panzergewinde'' sizes are named with the prefix ''PG'' plus a nominal number which approximately corresponds to the maximum cable diameter (in millimeters) that can be passed through the conduit. Because the walls of the conduit are usually relatively thin, the thread depth is limited. Thus a thread angle of 80° is used. The ''Verband der El ...

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] |
Garden Hose
A garden hose, hosepipe, or simply hose is a flexible tube used to convey water. There are a number of common attachments available for the end of the hose, such as sprayers and sprinklers (which are used to concentrate water at one point or to spread it over a large area). Hoses are usually attached to a hose spigot or tap. Terminology The alternative term "hosepipe" is a chiefly British, South African, and southern US usage; "hose" or "garden hose" is the predominant term in other English-speaking areas. The term " hose" is also used for other types of flexible, water-carrying tubes such as fire hose used by fire departments. Description Garden hoses are typically made of extruded synthetic rubber or soft plastic, often reinforced with an internal web of fibers. As a result of these materials, garden hoses are flexible and their smooth exterior facilitates pulling them past trees, posts and other obstacles. Garden hoses are also generally tough enough to survive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN Thread
The AN thread (also A-N) is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army Air Corps and Navy, hence AN. The Air Corps-Navy involvement is also the origin of the red/blue color combination that was traditionally used in the anodized finishing process. AN sizes range from -2 (dash two) to -32 in irregular steps, with each step equating to the OD (outside diameter) of the tubing in -inch increments. Therefore, a -8 AN size would be equal to -inch OD tube. However, this system does not specify the ID (inside diameter) of the tubing because the tube wall can vary in thickness. Each AN size also uses its own standard thread size. AN fittings are a flare fitting, using 37° flared tubing to form a metal-to-metal seal. They are similar to other 37° flared fittings, such as JIC, which is their industri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
