Api 570 by Steve Uk

API 570 is a specification for the inspection, repair, and alteration of piping systems. The purpose of this specification is to provide guidance for those who inspect, repair, or alter piping systems that are made of ferrous metals. This specification covers all aspects of piping inspection, including visual examination, nondestructive testing, dimensional measurements, material verification, and hydrostatic testing.

API 570 also provides guidance on how to properly document the condition of piping systems so that they can be accurately repaired or replaced.

API 570 is an international code for the inspection, repair and alteration of pressure vessels. The code covers all aspects of pressure vessel inspection, including welding, NDT, metallurgy and corrosion control. It is widely used in the oil & gas industry, as well as other industries where pressure vessels are used.

The code was first published in 1977, and has been revised several times since then. The most recent revision was published in 2016. API 570 is a valuable resource for anyone involved in the inspection or repair of pressure vessels.

It provides guidance on all aspects of the process, from welding to NDT to corrosion control. If you’re involved in this kind of work, it’s definitely worth familiarizing yourself with the code.

API 570 – Piping Inspection Code is an inspection code developed and published by the American Petroleum Institute (API). The code covers in-service inspection, rating, repair, and alteration of metallic piping systems and their associated pressure relieving devices that operate up to 1000°F. Inspection is the practice of examining the physical condition of materials, components, or entire pieces of equipment in order to determine if they are suitable for continued service.

Rating is the determination of a numerical value which corresponds to the operational capability or fitness-for-service of a material, component, or piece of equipment. Repair is any work done on damaged or defective material, components, or equipment in order to return it to at least its original strength and function. Alteration is any change made to existing material, components, equipment, processes, procedures, etc., that results in a change to how it was originally intended to be used.

The most common methods of NDT used for in-service inspection as specified in API 570 are: visual examination (VT), liquid penetrant testing (PT), magnetic particle testing (MT), eddy current testing (ET), radiographic testing (RT), ultrasound testing (UT) and acoustic emission testing (AET). Other NDT methods may also be used when deemed fit by the inspector. Repair can be either minor or major.

Minor repairs include welding/grinding out small defects (< 1/16” deep x 1/8” long) followed by reexamination with an appropriate NDT method; while major repairs include removing sections of pipe (>1’ long) and replacing them with new sections welded in place using an acceptable welding procedure followed by reexamination with an appropriate NDT method. All repaired areas shall have full Penetrant Testing coverage regardless if it was a minor or major repair. Alterations generally fall into two categories: those that require engineering analysis/design calculations prior to being carried out; those that do not require engineering analysis/design calculations prior to being carried out.

Q: What is the Api 570 Exam

The API 570 Exam is a four-hour, open book exam that is taken by candidates who are seeking to become certified in welding inspection and metallurgy. The exam tests the candidate’s knowledge of welding procedures, methods, materials, and safety.

Q: Who is Eligible to Take the Api 570 Exam

API 570 is a certification exam administered by the American Petroleum Institute that tests an individual’s knowledge of piping inspection. The exam is open to anyone with at least two years of experience working in the field of piping inspection.

Q: How Often is the Api 570 Exam Offered

The API 570 Exam is offered four times per year.

What is the Passing Score for the Api570 Exam

The American Petroleum Institute (API) 570 Certified Pipework Inspector Program was created to provide individuals in the petroleum and petrochemical industries with a comprehensive set of skills and knowledge for inspection, repair, alteration, and rerating of in-service piping systems. The program covers all aspects of pipework inspection including visual examination, nondestructive examination (NDE), material testing, fitness-for-service (FFS), and pressure testing. The API 570 certification exam is a computer-based test consisting of 150 multiple-choice questions.

The passing score for the exam is 70%.

Conclusion

The American Petroleum Institute (API) 570 exam is a test that covers the inspection, repair, alteration, and rerating of process piping systems that operate at elevated temperatures and/or pressures. The API 570 exam is divided into two parts: Part I covers theory and Part II covers calculation problems.
