02386 A NEW CARBURIZATION RESISTANT ALLOY FOR ETHYLENE PYROLYSIS FURNACE TUBES

Product Number: 51300-02386-SG

ISBN: 02386 2002 CP

Author: Y.Nishiyama, H.Semba, K.Ogawa, Y.Yamadera, Y.Sawaragi, and S.Kinomura

Publication Date: 2002

$20.00

A new wrought alloy has been developed for use as furnace tubes in ethylene pyrolysis plants. This alloy has an excellent carburization resistance due to uniform formation of protective Al2O3 oxide scale on the metal surface. Laboratory corrosion tests have been carried out to evaluate carburization resistance of the developed alloy.

51317--9785-Oxidation Kinetics of Cast Alumina-Forming Austenitic Alloys in Steam

Product Number: 51317--9785-SG

ISBN: 9785 2017 CP

Author: Benjamin Church

Publication Date: 2017

$20.00

Alloy tubes used in petrochemical processing reactor systems are often subjected to oxidizing conditions in high temperature steam such as during de-coking cycles. A new class of heat resistant austenitic cast alloys are being developed that are designed to form protective oxides of alumina.

Influence Of Ternary Additives On Electrochemical And Mechanical Behaviors Of Electroless Ni-P Coatings

Product Number: 51322-17841-SG

Author: Omar Chaa, Ahmad Raza Khan Rana, George Jarjoura

Publication Date: 2022

$20.00

Corrosion and wear resistance has always been among the highly important parameters for
equipment and piping in oil and gas facilities. The corrosion is considered as the deterioration
of materials as a result of electrochemical reaction with surrounding environment or contained
service. Wear is defined as the removal and deformation of material due to mechanical
interaction between two or more objects. Increased demand for surface protection and reduced
operative costs touts for protective coatings with improved mechanical, electrochemical, and
tribological properties.

Technical Review on the Existence of Type B (Alumina) Inclusion at Hot Steel Making Process

Product Number: MPWT19-15601

Author: Yasser S. Al-Subhia, Mishal M. Al-Ashrahb*

Publication Date: 2019

$0.00

It is well known in the hot rolled steel making business that nonmetallic inclusions play critical
role in defining steel performance. The objective of this paper is to study laminations that were
detected via Phased Array UT system in X60MS Class-C High Frequency Welded Pipe intended for
offshore application. The linear intermittent laminations appear along the pipe and adjacent to
the weld seam from both sides at a width of 30 to 40 mm with various depths. Technical review
was carried out on 5 available pipes, pertaining to the same heat of the original pipe identified
earlier with lamination, through model experiments; both on the laboratory and on the industrial
scale. At the beginning, depth and distribution of detected laminations were analyzed by manual
UT mapping using normal beam probe. Metallurgical analysis via Energy Dispersive X-ray (EDX)
was carried out on three samples to determine the chemical composition as well as the
morphology of the lamination. The type of inclusion which turned out to be type B (Alumina-
Al2O3) inclusion was identified by evaluating EDX results using Method A per ASTM E45. As it is
a pure material based incident, failure analysis was carried out by the steel maker to identify the
associated root causes from process control prospective and the appropriate preventive
measures to avoid reoccurrence. Eventually, the applied quality control measures during
manufacturing process of HFW pipes, represented in the deployment of UT systems, were
reviewed to identify the reason behind missing such important defect before pipes are being
shipped to the client.
