Trouvay & Cauvin has produced the 2001 edition of its piping brochure. It reflects the latest changes in American standards, particularly the API and ASME/ANSI standards organisations. Designed for use by industrial end users, especially in the oil and chemical industries, within purchasing, quality assurance, project management and maintenance departments, it is also suitable for engineering companies, piping contractors and fabricators. It contains primarily a description of the materials (carbon steel, stainless steel, alloy steels, special alloys) and dimensions of piping equipment, including line pipe, casing and tubing pipe, welding and forged fittings, flanges, sealing products, petroleum valves and industrial valves.
