The out-of-squareness see Figure 1 shall 1020-82 exceed: It includes more stringent quality and testing requirements than those in BS EN The faster, easier way to work with standards. These limits refer to the gap between the extreme point of the deviation and the prolongation of the normal contour of the pipe.
BS EN 10208-2:2009
This approach is common, for example, for transmission pipelines. Many years of experience.
Such enhanced requirements are addressed in requirement class B and considered in EN Alloy fine grain steel tubes. The notches shall be sufficiently separated from each other in the longitudinal direction and from any remaining reinforcement, to give clearly identifiable separate ultrasonic signal responses.

The type of pipe and the type of heat treatment as given in the steel name shall be specified by the purchaser. The Charpy impact energy requirements in this document have been derived from established data, in accordance with EPRG recommendations, and are intended to prevent the occurrence of long running shear fracture in pipelines transporting clean, dry natural gas.
When this examination fails to disclose mechanical damage as the cause of the irregular surface, but indicates that the irregular surface may be attributed to a hard spot, the dimensions of the area and, if necessary see 8. D specified outside diameter; Dmin specified minimum outside diameter; T specified wall thickness; Tmin specified minimum wall thickness.

At the discretion of the manufacturer, a circumferen- tial tape or a caliper gauge may be used.
CEV of 0,43 may be agreed.
enn Method of test at ambient temperature EN In the case of sealing against the end face of the pipe by means of a ram, a compressive longitu- dinal stress is produced. In such a case an ultrasonic test in accordance with EN shall be used. Steel pipes for pipelines for combustible fluids.
Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. This is designated requirement class A and considered in EN It is the ultimate responsibility of the user to select the appropriate requirement class for the intended application.
