First use vernier calipers to measure the outer diameter of the pipe, and then measure the wall thickness of the resulting figure is the pipe size. Need to measure the parameters are:

1, nominal diameter: D.

2, bending radius (usually the standard elbow bending radius is 1.5 * tube outside diameter): R.

3, wall thickness that is, wall thickness: T.

Measuring tools are usually divided into general-purpose measuring tools, specialized measuring tools and special measuring tools 3 categories. General measuring tools:

Can measure the length or angle of many types of workpiece measuring tools. This type of measuring tool has the most varieties of specifications, the use of the most extensive, there are blocks, angle blocks, multi-faceted prisms, sine gauge, calipers, micrometers, percentage tables (see percentage tables and micrometers), multi-tooth indexing table, comparator, laser length gauge, tool microscope, three-coordinate measuring machine and so on.

Extended information:

The materials of the bends are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. Bend a variety of parameters are input into the pipe bender, by the pipe bender to bend the pipe. Bender can be broadly divided into CNC pipe bender, hydraulic pipe bender and so on.

The use of pipe bender: hydraulic pipe bender is mainly used for electric power construction, public railroad construction, boilers, bridges, ships, furniture, decoration and other aspects of the pipeline laying and construction, with multi-functional, structurally sound, easy to operate, easy to move, fast installation and other advantages.
