A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
Fred A. Lennon and Cullen B. Crawford founded Crawford Fitting Company in Cleveland, Ohio, in July 1947 to manufacture the Swagelok tube fitting, which used a two-ferrule design to “swage” or form the tube and lock it into place. One year later, Lennon bought out Crawford and continued to grow the business.
A screw extractor held in a tap wrench. A screw extractor is a tool for removing broken or seized screws.There are two types: one has a spiral flute structure, commonly called an easy out after the trademarked name EZ-Out; [clarification needed] the other has a straight flute structure.
For pipe sizes of NPS 14 inch (DN 350) and greater the NPS size is the actual diameter in inches and the DN size is equal to NPS times 25 (not 25.4) rounded to a convenient multiple of 50. For example, NPS 14 has an OD of 14 inches or 355.60 millimetres, and is equivalent to DN 350.
Similar to a wood screw, except that it is generally much larger running to lengths up to 15 in (381 mm) with diameters from 0.25–0.5 in (6.35–12.70 mm) in commonly available (hardware store) sizes (not counting larger mining and civil engineering lags and lag bolts) and it generally has a hexagonal drive head.
The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
BS 93:1951 — Specification for British Association (B.A.) screw threads with tolerances for sizes 0 B.A. to 16 B.A. BS 93:2008 — British Association (B.A.) screw threads — Requirements The angle of the thread is 47.5° [ 4 ] : 2 and the depth of thread is 0.6 times the pitch with rounded tops and bottoms.
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends. 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 ...
