API 5L standard terminology

A flaw: It is the size and / or density exceeds the standard requirements and acceptance limits shortcomings.

2 shortcomings: It is checked using a standard method of testing described in the products or the surface of the inner wall discontinuities or irregularities.

3 Layered: internal metal layer is usually formed separately from the steel sheet parallel to the surface.

4 Body: For welded steel pipe means excluding the weld and heat affected zone Germany entire pipe.

5 side: including steel 100mm each end within the length of the pipe.

6 wrong side: steel / steel radial offset between the edges.

7 Cold Forming: without heating the steel strip or plate is molded into the processes.

8 Steel Grade: steel intensity level indicates the name. And steel grade (ie grade steel name) the same.

9 service conditions: by the purchaser in the contract specified conditions of use (or non-maritime service into non-acidic, acidic and / or marine service).

10 require authentication process: refers to steel manufacturing process, product characteristics affect response to comply with this standard (except chemical composition and size) of the final operation.

11 Product specifications PSL: API5L criteria to determine the level of the two grade product specifications, (PSL1 and PSL2 provides different standard levels. PSL2 carbon equivalent, notch toughness, maximum yield strength, tensile strength, maximum yield ratio, Delivery status made mandatory.

12 test batch: batch using the same furnace steel manufacturing in the same conditions, through the same process pipe, made of the same specified outside diameter, wall thickness specifications of a predetermined number of pipe.

13 Product Analysis: steel pipe, steel grade, steel chemical analysis.

14 equipment calibration: the non-destructive testing equipment to adjust to the specified reference value activities.

15 Undercut: Weld metal adjacent to the weld toe in a groove formed on the base material and is not full.
