Detailed Product Description: | Flange | Hebei professional production pipeline flange million gold | manufacturer of stainless steel welded flange provided by Hebei billion in gold piping. Flange | Hebei billion of professional production pipeline flanges | large-diameter welded flange gold price is Hebei billion Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) 2014 been newly launched upgraded stainless steel flange stainless steel flange Name: Stainless law Portland English (Stainless steel flange) Specifications: 1/2 "to 240" (10-6000) Pressure Rating: 0.6Mpa ~ 32Mpa, 150Lb ~ 2500Lb, PN0.25-PN42.0 Material: 304,304 L, 321,316, 316L, 310S other materials Ministry of Chemical Industry Standard: HG5010-52 ~ HG5028-58, HGJ44-91 ~ HGJ65-91, HG20592-2009 (PN series), HG20615-2009 (Calss Series) Application: Boiler and Pressure Vessel, oil , chemicals, shipbuilding, pharmaceutical, metallurgy, machinery, food and other industries. Stainless steel flange is a discoid parts, the most common projects in the pipeline, stainless steel flanges are used in pairs. In the pipeline project, mainly for stainless steel flange connecting pipes. In the pipeline need to be connected, and a variety of mounting a flange, low-pressure pipe can be connected using wire stainless steel flanges, four kilograms more than the use of pressure welding flanges. Between the two flange gaskets, and then fastened with bolts. The flanges have different pressures and different thicknesses using different bolts. Stainless steel flange Caution: 1, to prevent the heat generated due Falangaijia between eye corrosion, welding current is not too large, less than about 20% carbon steel electrode arc not too long, fast cooling between layers to narrow weld is appropriate. 2, should be kept dry hyperbaric welding flange using a supplier of titanium calcium type should be dried 150 ℃ 1 hour a low hydrogen type should be dried 200-250 ℃ 1 小时 (not repeated drying, otherwise the drug skin easily cracking spalling), to prevent the electrode coating viscosity oil and other dirt in order to avoid causing increased carbon content and impact of the weld weldment quality. 3, stainless steel pipe flanges when welding high-quality large-diameter welded flange, subject to repeated heating carbide precipitation, reduce corrosion resistance and mechanical properties. 4, chromium stainless steel pipe flanges after welding, hardening of American Standard flange large, easy to crack. If using the same type of chromium stainless steel rod (G202, G207) welding must be above 300 ℃ preheating and welding process slow cooling of about 700 ℃. If you can not post weld heat treatment weldments should be made of stainless steel pipe flanges electrode (A107, A207). 5, stainless steel Flange for improving the corrosion resistance and weldability appropriately increased stability and appropriate elements Ti, Nb, Mo, etc., welding better than chrome steel flange. When using the same type of chromium steel flange rod (G302, G307), the tempering treatment should be carried out above 200 ℃ 800 ℃ or preheating and the welding. If you can not be heat treated stainless steel weldments welded flange manufacturers, should be made of stainless steel pipe flanges electrode (A107, A207). 6, stainless steel pipe flanges, welded flange welding with good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery. |
