Draw a horizontal LINE perpendicular and to the right measuring 7" (H dimension from Welded Fittings-Flanges chart), which will represent the length of the reducer. Step 3. Create the small diameter end of the reducer by drawing an 8" (NPS) vertical LINE up from the right end of the reducer. Step 4.
01-06-2021· Pipe fittings and pipe lengths joined by butt welds require end prep to ensure the integrity of the final welded joints. Image credit: mady70/Shutterstock.com. Flanges are also used, with the resulting flanged sections of pipe connected via bolts. The use of flanges makes breaking the pipeline feasible so as to enable replacement of valves, etc.
Removable Spool and Blind Flanges: This method involves removing a complete section of the line between two flanges (the spool) and fitting blind flanges to close the two ends of the line. This gives a very positive visual indication that the line is closed. Blind flanges are used to close any pipe …
TEPPFA is The European Plastic Pipe and Fittings Association. Its 13 multinational company members and 15 national associations represent 350 companies that manufacture 3 million tonnes of plastic pipes and fittings annually.
Casting flange is a commonly used flange technology, which has the advantages of high production efficiency and low production cost, and is suitable for medium and low pressure pipelines. Forged pipes are recommended for pipes operating at high pressures.

Flanges shall be square to the axis of the pipe to within an angle of 0 ° ‑ 18' (0.3 °) I.E. 0.05mm per centimeter measured across the face of the flange, with the pipe adequately supported. 4.2.5. Bolt Holes of Flanges. Flange bolt holes shall straddle the established centerlines (Horizo n tal or vertical).
The piping MTO is a list of all piping items required to purchase, fabricate and construct the design. This list will contain all piping items, pipe, fittings, flanges, gaskets, bolts, nuts, elbows, reducers, tees, valves, speciality items etc. Everything must be accounted for. Bill Of Materials (BOM)

Pre-Fabrication of Pipe Spools. Pipe spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in fabrication shops. Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted …
This is of particular advantage for ductile iron piping systems which have flanges at each fitting and spool piece. For alloy piping systems the number of flanges is greatly reduced so the need to hydrotest the system is less. Flushing and hydrotesting can be done safely provided certain precautions are taken.

Production planning helps you manage open time, ensuring it is well-utilized, while being careful not to create delays. Planning should maximize your operational capacity but not exceed it. It's also wise not to plan for full capacity and leave room for the unexpected priorities and changes that may arise. 4.
connections eliminates the need for expensive tools and reduces labor costs. Flexible A grooved piping system is more ﬂexible than traditional pipe joining methods such as welded, threaded and ﬂanged. A grooved piping system can be easily and quickly modiﬁed or retroﬁtted. Eliminates Welding Fumes & …
The FCW provides the installer with an additional length of pipe, usually 100 to 150 mm longer than what is indicated on the design drawings, to allow for field adjustment.What has to be considered, and what prompts the need for a FCW, is the actual, as-installed, location of both the fixed equipment that the pipe assemblies may connect to and the actual installed location of the pipe assembly itself.
07-09-2011· Mechanical key-lock joints are used for pipe to pipe joining and adhesive joints are for pipe to fittings and fittings to fittings. 5.1.2 Handling, installation, fabrication and inspection at site shall be carried out under the supervision of the manufacturer's field service engineer qualified to do the job as per CONTRACTOR giving specific requirements for handling RTRP pipes and fittings.
Piping components are mechanical elements suitable for joining or assembly into pressure-tight fluid containing piping systems. Components include pipe, tubing, fittings, flanges, gaskets, bolting, valves and devices such as expansion joints, flexible joints, pressure hoses, traps, strainers, in-line portions of instruments and separators.
Important Information. There was an ASME B16.9 change in the take outs for 0.75" BW LR elbows in 2007. The change for 90° els take out was to make them 1.5" instead of 1.125".This also affects the 45° elbows as well. The factory-made 45° LR Els Take outs are 0.75".The field-cuts will be 0.9375".Some handbooks, wheels, and slides still show the old sizes so you will need to mark them with ...

18-06-2013· These 7 factors are all involved in choosing the right flange for the right application to maximize its functionality. Types. It's pretty easy to identify the type of flange by how it looks. First, identify the tops by determining whether a flange has a flat face, threaded bore, lap joint, weld neck, socket weld, or tongue and groove.
