Standard & Grade :ASTM A179 Boiler tube Ends:Square Ends/Plain Ends (straight cut, saw cut, torch cut), Beveled/Threaded Ends Delivery state: Annealed, normalized, tempered. surface oiled, black painted, shot blasted, hot dipped galvanized. Packing:Bundle or bulk , wooden case or other seaworthy packing or for the client's requirement

Boiler pipe is one kind of seamless pipe, and their production style is same. However boiler pipe has strict requirement for steel grade used. According to the usage temperature differences, boiler pipe can be divided into general boiler tube and high pressure boiler pipe. Different country have their own standard for boiler pipes, and they are widely used for heating surface of high temperature boiler, heater, economizer, super heater, re-heater, and petrochemical industry and so on. Production Size Range: OD 21.3mm to 508mm x WT 3mm to 50mm Main standards consist of DIN17175, EN10216, ASME SA-106M, SA-192M, SA-209M, SA-210M, SA-213M, SA-335M, GB3087, GB5310, JIS G3456, JIS G3461, JIS G3462. Advantages of us 1.Professional manufacturer for seamless steel pipe since 2006. 2.Competitive price due to factory production. 3.Comprehensive products list, supplying you with more choice. 4.More than 10years export experience. We can successfully deal with all the unexpected matter during the whole export procedures. FAQ 1.What is the difference between high pressure boiler tubes and low and medium pressure boiler tubes? The differences between high pressure boiler tubes and zhi low and medium pressure boiler tubes are as follows: A.the execution standards is different B.Different use environments High pressure boiler tubes: the working pressure is generally above 9.8Mpa, and the working temperature is between 450â?? and 650â?? Low and medium pressure boiler tubes: the working pressure is generally not more than 5.88Mpa, and the working temperature is below 450â?? C.Different materials Suitable materials for high pressure boiler tubes: 20G, 20MnG, 25MnG, 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. Suitable materials for low and medium pressure boiler tubes: 10#, 20# D.Different prices The price of high pressure boiler tubes is higher than that of low and medium pressure boiler tubes. 2.The difference on materials between fluid pipe and boiler pipe? The working environment of fluid pipe is relatively peaceful Boiler tubes have low carbon, strict control of harmful elements, no segregation of carbon elements and good welding performance 3.Why should boiler tubes be heat treated? Stress concentration will occur after bending. Heat treatment is mainly to eliminate stress.

China good quality boiler membrane water wall with favorable price is main radiation heat surface, arranged inside the boiler chamber and proceeds the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end heat surface and proceed the heat exchange directly with the high temperature fume. The water wall and convection tubes are the main heat surface of the boiler, the tubes diameter for both Generally used Ï?51~60mm boiler streel tubes, also as the request. China good quality boiler membrane water walls with favorable price that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Membrane water wall are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the steam boiler.
