It is applicable to hot-rolled steel surfaces prepared for painting by methods such as blast-cleaning, hand and power tool cleaning and flame cleaning, although these methods rarely lead to comparable results. Essentially, these methods are intended for hot-rolled steel, but blast-cleaning methods, in particular, could also be used on cold-rolled steel of sufficient thickness to withstand any deformation caused by the impact of the abrasive or the effects of power tool cleaning.

KEY FEATURES: • This technique is growing in importance. • The first comprehensive book in this subject. A practical and comprehensive account of the technology and applications of hydroblasting, a technique used more and more in the preparation of steel and other surfaces. Steel surfaces will corrode unless they are properly prepared and coated. Such corrosion can have disastrous effects (eg bridge collapse) therefore the preparation of the surface is of major importance. Due to environmental pressure to move away from grit-blasting, high-pressure water can now be used to prepare surfaces, with few environmental costs. This book systematically and critically reviews the state of current hydroblasting technology and its applications. The book is essentially practical in nature and is written by an expert in the field.

This book looks at the applications of coating in piping, valves and actuators in the offshore oil and gas industry. Providing a key guide for professionals and students alike, it highlights specific coating standards within the industry, including ISO, NORSOK, SSPC and NACE. In the corrosive environment of a seawater setting, coatings to protect pipes, valves and actuators are essential. This book provides both the theory behind these coatings and practical applications, including case studies from multinational companies. It covers different offshore zones and their corrosivity level alongside the different types of external corrosion, such as stress cracking and hydrogen-induced stress cracking. The key coatings discussed are zinc-rich coatings, thermal spray zinc or aluminum, phenolic epoxy and passive fire protection, with a review of their defects and potential failures. The book also details the role of coating inspectors and explains how to diagnose faults. Case studies from companies such as Aker Solutions, Baker Hughes, Equinor and British Petroleum illustrate the wide range of industrial applications of coating technologies. This book is of interest to engineers and students in materials, coating, mechanical, piping or petroleum engineering.

This handbook is an in-depth guide to the practical aspects of materials and corrosion engineering in the energy and chemical industries. The book covers materials, corrosion, welding, heat treatment, coating, test and inspection, and mechanical design and integrity. A central focus is placed on industrial requirements, including codes, standards, regulations, and specifications that practicing material and corrosion engineers and technicians face in all roles and in all areas of responsibility. The comprehensive resource provides expert guidance on general corrosion mechanisms and recommends materials for the control and prevention of corrosion damage, and offers readers industry-tested best practices, rationales, and case studies.

Hot-dip galvanization is a method for coating steel workpieces with a protective zinc film to enhance the corrosion resistance and to improve the mechanical material properties. Hot-dip galvanized steel is the material of choice underlying many modern buildings and constructions, such as train stations, bridges and metal domes. Based on the successful German version, this edition has been adapted to include international standards, regulations and best practices. The book systematically covers all steps in hot-dip galvanization: surface pre-treatment, process and systems technology, environmental issues, and quality management. As a result, the reader finds the fundamentals as well as the most important aspects of process technology and technical equipment, alongside contributions on workpiece requirements for optimal galvanization results and methods for applying additional protective coatings to the galvanized pieces. With over 200 illustrated examples, step-by-step instructions, presentations and reference tables, this is essential reading for apprentices and professionals alike.

This Part defines a number of surface preparation grades but does not specify any requirements for the condition of the substrate prior to surface preparation. Highly polished surfaces and work-hardened surfaces are not covered by this Part.
