“l am your EAR and EYE for Higher Quality Requirments!”


Producing of natural gas API line pipes or any other industrial products does not mean finishing when you welded and coated then have buried them to the underground. Your pipes must stand against higher presure and ambient of heavy corrosion. And also your products must survive 40 – 50 years or more that’s why testing, standards, specifications, ITP, procedures and hiring freelance inspector is so much important.
Inspector thinking deeply about specification!

What is the Freelance Inspector?

Small hole on your corrosion coating without protection and just only a micro crack inside the weld bead can ruin or destroy your Billion Dolars Project maybe hunderds of lifes. Due to the this concerns to be freelance inspector is very important, critical and serious job like selling, manufacturing, QC/QA and planning maybe more.

Don’t Forget!

Remember, Challenger spacecraft disaster caused by refusing of small sealing test results! Whereas, inspector engineer had warned the management before rocket launching about the temperature drop down under the design temperature of fuel tanks sealings but nobody has cared this concern!

Adherence to standards, specifications, concentration, empaty and proactive approching are the keys for the successful completion of huge project and 3rd party inspection activities as a Freelance Inspector!

Some technical informations for Api line pipe production,

Freelance Inspector in Turkey!
SubSea Pipes Final Coating visual inspection on shore!

For the natural gas pipe line and to produce line pipes, the most important and popular standard specification is API. What is the API standard and API psl 1 and psl 2 pipes? This article is based on API Spec 5L, 46th Edition. to prepare of this document. The API technical committee maintained the concept of two basic levels of standard technical requirements for line pipe expressed as two product specification and quality levels (PSL 1 and PSL 2).

After Charpy toughness test fracture surface!

How do PSL 1 and PSL 2 Pipes work?

Level PSL 1 provides a standard quality level for line pipe. Level PSL 2 has additional mandatory requirements for higher quality for chemical composition, notch toughness and strength properties and additional NDT. Requirements that apply to only PSL 1 or to only PSL 2 are so designated. Requirements that are not designated to a specific PSL designation apply to both PSL 1 and PSL 2 pipe.

The API technical committee also recognized that the petroleum and natural gas industry often specifies additional requirements for particular applications.

For other specific requierment.

In order to accommodate such needs, optional additional requirements for special applications are available, as follows: ⎯ PSL 2 pipe ordered with a qualified manufacturing procedure (Annex B), the requirements of which have been enhanced to include verification detail of critical processes in the production of feedstock material.

Inspector controlling corrosion!

line pipe manufacture and product testing and inspection; API pipes demanded with resistance to ductile fracture propagation in gas pipelines (Annex G); PipeS for sour service (Annex H); ⎯ Ordered as “Through the Flowline” (TFL) pipe (An. I); ⎯ PSL 2 pipes required for offshore service (Annex J);

Inspector testing
API 5L Bending test!

Different types of line pipes,

Some specific API pipes.The following new annex is added to this Standard. – Equations for threaded and coupled pipe and background equations for guided bend and CVN test (Annex P). The requirements of the annex apply only when specified on the purchase order. When pipe is ordered for dual or multiple applications, the requirements of more than one annex for special applications can be invoked.

Inspector Mechanical Test
After tensile test!

If the Technical conflict arises between purchaser and vendor!

In such instances, if a technical conflict arises due to applying the requirements of more than one annex for special applications, the most stringent requirement applicable to the intended service shall apply.

Inspector UT test
Automatic UT Calibration signals!

This Standard does not provide guidance on when it is necessary to specify the above supplementary requirements. Instead, it is the responsibility of the purchaser to specify, based upon the intended use and design requirements, which, if any, of the supplementary requirements apply for a particular purchase order.

l love to be inspector for higher quality requirments and sharing experience of years!
