1) Internally coating gas pipelines with epoxy coatings was developed in the 1950s to reduce corrosion and increase pipeline efficiency.
2) Epoxy coatings create a smooth inner surface that allows gas to flow more easily, reducing pressure drops and increasing flow rates. This can allow pipelines to transport more gas without increasing size.
3) Studies have found that epoxy coatings can increase a pipeline's gas transport capacity by 5-20%, reducing operating costs through lower compression needs over the lifetime of the pipeline.

Stainless steels contain 10.5-30% chromium which forms a passive oxide layer protecting the steel from corrosion. Common types include martensitic, ferritic, austenitic, and duplex stainless steels. Martensitic stainless steels can be hardened through heat treatment while ferritic stainless steels have higher ductility and corrosion resistance. Duplex stainless steels have a mixed austenite and ferrite structure providing high strength and pitting/stress corrosion resistance. Austenitic stainless steels have excellent ductility and toughness down to cryogenic temperatures and are widely used in chemical plants and food processing. Proper welding techniques are required to prevent issues like sensitization, hot cracking, and sigma
Stainless steels are alloy steels with a nominal chromium (Cr) content of at least 11 weight percent (wt %), with or without other alloy additions. The oxidation and corrosion resistance of these alloy steels are attributed to the presence of a passive chromium-rich oxide film on the surface. The chromium-rich oxide can be damaged, but will quickly reform if oxygen is available. When exposed to conditions that damage the passive oxide film, stainless steels are subject to corrosive attack.
The rate at which a stainless steel develops a passive film in the atmosphere depends on its chromium content. Polished stainless steels remain bright and tarnish-free under most atmospheric conditions. Exposure to elevated temperatures increases the thickness of the oxide film.

The document discusses corrosion in various industries. It first discusses corrosion in thermal plants during shutdowns when ambient air contacts metal surfaces. Differential aeration corrosion can occur. It then discusses corrosion issues for wind turbine monopile foundations, including external differential aeration corrosion and internal galvanic corrosion between the monopile and transition piece. Corrosion is also discussed for oil transport pipes and steel reinforced concrete, where differential aeration corrosion can reduce the cross-sectional area and strength capacity of the reinforcement.
The document contains plans and details for a timber roof structure designed by Aaron Kaira. It includes a roof structure plan showing timber rafters and purlins, and sections detailing connections. Rafters are 250x50mm timber at 1200mm centers. Purlins are 75x50mm timber at 1200mm centers. Prefabricated box beams are used to support the rafters. The roof is covered with 0.5mm galvanized steel sheeting over rigid board insulation.
Field welding and cutting ductile iron pipeLudi Lunar
This document provides guidance on field welding and cutting of ductile iron pipes. It discusses that ductile iron pipe manufacturers should be consulted for their recommendations on field welding. While field welding of ductile iron is not generally supported, circumstances may require it for items like retainer rings. The procedures are only intended for qualified welders experienced in welding cast ferrous materials. Shielded metal arc welding using 44% or 55% nickel-iron electrodes is recommended for ductile iron, without need for preheating. Proper preparation of the welding area is important for success.
The document provides information about the Intelok steel framing system from Vantrunk. It describes the Intelok channel as having serrated flanges which increase slip resistance when used with channel nuts. The channel comes in deep and shallow profiles and can be plain or slotted. Tables give load ratings and span capabilities for different channel sizes. Information is provided on ordering lengths, finishes and part numbers for the channel system.

Large AC motors are defined as having a power rating greater than specified NEMA limits, a stator winding constructed by hand, or operating at voltages over 2300V. They use large enclosures to protect internal components from environmental conditions. Key components include stators constructed from laminated steel and copper windings, and rotors made from cast aluminum or copper bars. Large bearings and accessories like space heaters are also required due to the motor size. Proper enclosure selection and component sizing are important to ensure reliable operation of large AC motors in various applications.
Within 18 months of completion or 12 months of use, Hitachi Valve will repair or replace defective products free of charge if the failure is due to design or manufacturing issues. Exceptions include improper use, damage from foreign objects, unauthorized repairs, natural disasters, or other causes beyond Hitachi Valve's control. Malleable iron is suitable for valves due to its high yield point to tensile strength ratio, stable properties over a wide temperature range, and good castability and machinability. Graphite gaskets and packing provide maintenance-free sealing for valves.
