Steam reformers are critical assets to many refining and chemical manufacturing plants and facilities, and it is well known that the reformer is one of the most challenging assets to maintain and operate. Common problems in reformer operations include burner firing, flue gas distribution, and catalyst damage.

Returning for its fourth year, the Pipe Tech Americas Summit 2013 will once again address and deliver solutions to the most critical challenges faced by all pipeline operators through a combination of case studies, keynote sessions, panel discussions, interactive workshops and networking activities.The program offers the experience and expertise of an outstanding speaker faculty gathered from industry, government and academia to discuss the latest regulatory developments, management best practices, construction planning and maintenance and inspection technologies that improve...

Various fired heater designs in refineries and chemical plants contain common headers (e.g. Arbor coil configurations, CCRs, etc.) as part of their overall serpentine coil design. Accessing the interior of individual coils through the common header is challenging; however, advanced engineering firms and mechanical decoking companies have developed unique common header snorkel delivery systems. These systems are temporarily inserted into the common header while the unit is offline, guiding both mechanical decoking pigs and intelligent pigs into the individual heater coils. The delivery systems are modular by design, eliminating the challenges associated with accessing individual coils, and they can be attached to short or long common headers.

Electroless nickel (ENC) is a family of coatings based on nickel-phosphorous metallic compounds. ENC was developed in 1943 by Abner Brenner, an electrochemist at the U.S. Bureau of Standards. While working on the electroplating of nickel onto nickel-tungsten surfaces, Brenner added hypophosphite chemical to the plating solution as a way to control surface oxidation. This addition increased the electric current efficiency, indicating the hypophosphite was promoting nickel deposition and supplementing the electroplating current.

Dear,Are there anyone have experience in about Rael-Time raiography technique to detect CUI on pressure vessel? I need to review this technique to detect large destilation column and 2000 mm OD pressure vessel.Regard,Bangkit WidayatJunior Inspection EngineerPT KMI

To your knowledge , is there any difference between "Full Radiography " and "100% Radiography"

In the summer of 2005, as part of CIA Inspection's (CIAI) ongoing, in house, research efforts to improve inspection capabilities for coke drums, a development program was initiated to integrate ACFM (Alternating Current Field Measurement) inspection technology with a proven laser and video inspection tool for coke drums. The goal was to provide fixed equipment managers with more information on which to base their repair decisions. With this new development, surface-breaking flaws can now be validated and sized without taking the vessel out of service.

We have been introduced to Infrared Thermography (IRT) since World War I and over the last decade the application of this technique has gained impetus. Today, the IRT application is widely used and accepted by many industries such as power generation plants, oil & gas industries, manufacturing factories, medicine, agriculture and biology etc. The technique has been recognized as a reliable tool for technical diagnostics in particular to condition monitoring and predictive maintenance.

History has taught us that we should trust, but verify! Verification of alloys to ensure they are composed of the correct alloying elements has been the realm of handheld x-ray fluorescence for the past four decades. Industries ranging from petrochemical, aerospace and fabrication (which are mission critical for the correct material), to contract testing services, metals recycling applications and many more have employed portable XRF for alloy verification for over 40 years.

Where i can find the information about the replace the Radiography test in the API 650 by the UT Phased array? is legal? is the API agree with the phased array method? ThankCristian

LOTIS utilizes laser profilometry to conduct internal steam reformer tube inspections. The data captured by LOTIS is exceptionally powerful when combined with our LifeQuest™ remaining life assessment capabilities, providing an integrated solution set for the process and syngas industries.

A unique technique for inspecting the floors of aboveground storage tank's (AST) emerged in the late 90's based on in-service robotic technology. The technology has come a long way since then, with new inspection and tank cleaning capabilities, greater operational efficiency and a much broader user base. The number of tanks inspected using in-service robotics has now exceeded the 700 mark.

Most common radiographic practices for circumferential weld testing are single wall and double wall techniques with certain variations in technique details. Different Codes deal with the number of exposures required and applicability of the technique for different combinations of pipe diameter and wall thickness. However, there are certain geometries where these conventional radiography techniques are not applicable, mainly because the weld is superimposed on some structural material inside the tube or pipe.

As per API 650/ Section-5 ( ERECTION) para 5.1.3 -- "Paint or foreign material shall not be used between surfaces in contact in the construction of the tank proper, except as permitted by para 5.2.1.9."Now para 5.2.1.9 states -- "If protective coating are to be used on surfaces to be welded, the coatings shall be included in the welding procedure qualification tests for the brand formulation and maximum thickness of coating to be applied."Now I have tried weldability performance of carbon steel coated by Inorganic Zinc Silicate and it is OK. Radiography is OK. Now for...

During retubing of "U" tube bundle we have found that the available material was not the correct one ,instead we have straight tube where we fabricated U bends as per original dimensions then we weld it to the straight section with 100% radiography. is this accepted by the code? i mean is it right practice ? if not which code does not allow that and why?

Part 1 in this 2 parts series laid the technical foundation for the methodology and technology. Part 2 will now demonstrate both through actual applications.
