1. Low fluid delivery welded steel pipe (GB / T3092-1993), also known as general welded pipe, commonly known as the clarinet. Welded steel pipe for conveying water, gas, air, oil and heating steam and other general low pressure fluid and other uses. Divided into ordinary steel pipe wall thickness and pick thicker steel; take over end into the form without the steel tube (fluorescent tubes) and with a steel pipe. Steel pipe with a nominal diameter size (mm), said nominal diameter is the diameter of the approximation. Traditionally commonly expressed in inches, such as 11/2 and so on. Low pressure liquid delivery welded steel pipe for conveying fluids in addition to direct, but also widely used as low pressure fluid galvanized welded steel pipe original. 2. The low pressure fluid galvanized welded steel pipe (GB / T3091-1993), also known as galvanized welded steel pipe, commonly known as white tube. Is used for conveying water, gas, air, oil and heating steam, heated and other general low pressure fluid or hot-dip galvanized welded to other uses (furnace brazed or welded) steel pipe. Pipe wall thickness is divided into ordinary galvanized steel pick and thicker galvanized steel; take over end into the form of a threaded galvanized steel pipe without threaded galvanized steel and band. Steel pipe with a nominal diameter size (mm), said nominal diameter is the diameter of the approximation. Traditionally commonly expressed in inches, such as 11/2 and so on. 3. Ordinary carbon steel wire casing (GB3640-88) is the industrial and civil construction, installation of machinery and equipment and other electrical installation work for the protection of steel wires. 4. straight seam welded steel pipe (YB242-63) is parallel to the longitudinal welds and steel pipe. Usually divided into metric welded steel pipe, welded tube, transformer cooling tubing and more. ---- Jinding stainless steel pipe 01 online customer Shandong Jinding Stainless Steel Pipe Co., Ltd. is a professional production of stainless steel pipe stainless steel pipe manufacturers, has focused on the production of stainless steel welded pipe, stainless Why use it as a production material, and here we take the material Introduction to analyze their differences? Applications austenitic and ferritic stainless steel is relatively wide, they have their own different characteristics, applications also exist essential difference between stainless steel pipe 316, want to know their own purposes, it should be aware of their identity and different. First of all we are saying is austenitic stainless Let us understand the characteristics under austenite, austenitic stainless steel is the most important category, 70% of its total production and accounts for stainless steel. According to alloying methods, austenitic stainless steel can be divided into chrome-nickel steel and iron-chromium-manganese steel two categories. The former nickel austenitic elements, is the subject of austenitic steels; the latter is based on manganese, nitrogen instead of expensive nickel-nickel steel. Generally speaking, good corrosion resistance of austenitic steels with good mechanical properties and process performance stainless steel pipe 304, but the strength, low hardness. Besides ferritic stainless steels, ferritic stainless steel containing chromium 11% -30%, substantially free of nickel stainless steel pipe 304 is nickel-steel, in the use of state organizational structure ferrite based. High strength ferritic stainless steel body and lower work hardening tendency, resistance to chloride stress corrosion, pitting, crevice corrosion, localized corrosion fine, but sensitive to intergranular corrosion, poor low-temperature toughness. 316 stainless steel welded pipe, stainless steel pipe, pipe industry by Shandong Jinding Jinding Stainless Steel Pipe Co., Ltd .. Shandong Jinding Stainless Steel Pipe Co., Ltd. (www.jdbxg.cn) strong, credible, in Dezhou steel industry has accumulated a large number of loyal customers.
