A U-bolt is a bolt in the shape of the letter U with screw threads on both ends.
22-419: U-bolts have primarily been used to support pipework , pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting. U-bolts are also used to hold ropes together. For example, a 40 Nominal Bore U-bolt would be asked for by pipe work engineers, and only they would know what that meant. In reality,
44-488: A compact pile of parts on a wagon and then assembled as a hollow structure at the job site. Wooden pipes were especially popular in mountain regions where transport of heavy iron or concrete pipes would have been difficult. Wooden pipes were easier to maintain than metal, because the wood did not expand or contract with temperature changes as much as metal and so consequently expansion joints and bends were not required. The thickness of wood afforded some insulating properties to
66-610: A mechanical engineering topic is a stub . You can help Misplaced Pages by expanding it . Pipework 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
88-403: A pipe is manufactured often forms as the basis for choosing any pipe. Materials that are used for manufacturing pipes include: Early wooden pipes were constructed out of logs that had a large hole bored lengthwise through the center. Later wooden pipes were constructed with staves and hoops similar to wooden barrel construction. Stave pipes have the advantage that they are easily transported as
110-584: Is a piping system with which most people are familiar, as it constitutes the form of fluid transportation that is used to provide potable water and fuels to their homes and businesses. Plumbing pipes also remove waste in the form of sewage , and allow venting of sewage gases to the outdoors. Fire sprinkler systems also use piping, and may transport nonpotable or potable water , or other fire-suppression fluids. Piping also has many other industrial applications, which are crucial for moving raw and semi-processed fluids for refining into more useful products. Some of

It is necessary to evaluate the mechanical behavior of the piping under regular loads (internal pressure and thermal stresses) as well under occasional and intermittent loading cases such as earthquake, high wind or special vibration, and water hammer. This evaluation
154-1120: Is the ASME Boiler and Pressure Vessel Code (BPVC). The BPVC provides rules for the design, fabrication, installation, inspection, care, and use of boilers , pressure vessels , and nuclear components. The code also includes standards on materials, welding and brazing procedures and qualifications, nondestructive examination, and nuclear in-service inspection. Other Notable Standardization Areas include but not limited to are; Elevators and Escalators (A17 Series), Overhead and Mobile Cranes and related lifting and rigging equipment (B30 Series), Piping and Pipelines (B31 Series), Bio-processing Equipment (BPE), Valves Flanges, Fittings and Gaskets (B16) , Nuclear Components and Processes Performance Test Codes. The journals published by ASME include: ASME offers four categories of awards: achievement awards to recognize "eminently distinguished engineering achievement"; literature awards for original papers; service awards for voluntary service to ASME; and unit awards, jointly awarded by six societies in recognition of advancement in
176-671: Is today multidisciplinary and global. ASME has over 85,000 members in more than 135 countries worldwide. ASME was founded in 1880 by Alexander Lyman Holley , Henry Rossiter Worthington , John Edison Sweet and Matthias N. Forney in response to numerous steam boiler pressure vessel failures. Known for setting codes and standards for mechanical devices, ASME conducts one of the world's largest technical publishing operations. It holds numerous technical conferences and hundreds of professional development courses each year and sponsors numerous outreach and educational programs.

198-478: Is usually performed with the assistance of a specialized ( finite element ) pipe stress analysis computer programs such as AutoPIPE, CAEPIPE, CAESAR, PASS/START-PROF, or ROHR2 . In cryogenic pipe supports, most steel become more brittle as the temperature decreases from normal operating conditions, so it is necessary to know the temperature distribution for cryogenic conditions. Steel structures will have areas of high stress that may be caused by sharp corners in
220-576: The 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt. The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe by the amount of fluid / gas it can transport. As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then a more convenient measurement system needs to be used. Four elements uniquely define any U-bolt: This article about

Generally, industrial piping engineering has three major sub-fields: Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress
418-664: The pipes which helped prevent freezing as compared to metal pipes. Wood used for water pipes also does not rot very easily. Electrolysis does not affect wood pipes at all, since wood is a much better electrical insulator. In the Western United States where redwood was used for pipe construction, it was found that redwood had "peculiar properties" that protected it from weathering, acids, insects, and fungus growths. Redwood pipes stayed smooth and clean indefinitely while iron pipe by comparison would rapidly begin to scale and corrode and could eventually plug itself up with
