Abstract SUMITOMO DP3 is a duplex steel with 25 chromium to resist the oil country tubular goods environments of hydrogen sulfide, chlorides and carbon dioxide. The higher alloying also produces higher strengths and more resistance to chloride stress-corrosion cracking than 22 chromium duplex stainless steel. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-570. Producer or source: Sumitomo Metal Industries Ltd.

Abstract NIROSTA 4002 is an apparatus structural steel with 13% Cr. It is used for crack-resistant installations in the mineral oil industry because it has a high level of resistance against hydrogen and hydrogen sulfide. This chromium steel requires a smoothened surface free from residues in order to achieve optimal resistance to corrosion. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SS-856. Producer or source: ThyssenKrupp Nirosta GmbH.

Fire Extinguishing

In China, as popularizing the technology of fully mechanized top-coal mining and increasing the strength and depth of mining, the gutter-up gob can be formed. But the work of fire preventing and extinguishing for its coal spontaneous combustion is more complexity and difficulty. In this paper, based on geology parameters and mining practice for 93up12 fully mechanized top-coal caving face in Nantun coalmine, the form and character of gutter-up gob are analyzed. According to the hidden danger of high temperature for spontaneous combustion in the gob, we adopt the comprehension technologies of fire extinguishing and preventing which include sealing air-leakage, grouting, and injecting compound gel with fly-ash, foam of retarding oxidation, liquid carbon dioxide, and gas of nitrogen. By putting in practice the pre-controlling technology in gutter-up gob and monitoring data of target gases, it obtains a good effect and ensures the safety in production of the fully-mechanized top-coal caving face.
