Introduction to the nominal diameter of 3pe anticorrosive spiral steel pipe
The nominal diameter of 3pe anticorrosive spiral steel pipe:For 3 PE anticorrosion 3 PE anticorrosive spiral steel pipe nominal diameter of the spiral tube mill to do a detailed introduce of the system, and the first antiseptic 3 PE anticorrosive spiral steel pipe diameter can be divided into inner diameter and nominal diameter, outside diameter, pipe material for anti-corrosion 3 PE anticorrosion with spiral steel pipe diameter D, said after the size of the outer diameter and wall thickness in the attachment, such as anti-corrosion outer diameter is 108 3 PE anticorrosive spiral steel pipe, wall thickness is 5 mm, with 5 D108 * said, plastic pipe also expressed in diameter, such as De63, other such as reinforced concrete pipe, cast iron pipe, galvanized pipe, such as using DN said,3pe anticorrosive spiral steel pipe factory generally adopts nominal diameter in design drawings.
Nominal diameter is a standard for the convenience of design, manufacture and maintenance, also known as nominal diameter, which is the specification name of pipes (or fittings).Nominal diameter of the pipe and the inner diameter, outside diameter are not equal, for example: nominal diameter is 100 mm 3 PE anticorrosive spiral steel pipe by 108 * 102 * 5 5 several kinds, such as 108 for the outer diameter of the pipe, said the pipe wall thickness, therefore, the inner diameter of the steel pipe for (108 * 5-5) = 98 mm, but it is not completely equal to the difference between the steel pipe diameter double wall thickness reduction, also, to say the nominal diameter is close to the inner diameter, but is not equal to the inner diameter of a pipe diameter of the specifications of the name.
