Steel prices _ Qingdao steel radiator radiator First, the scope (the service area, the pilot operating room) This standard applies to a new system of Baotou Steel tube radiator selection of two heat exchangers, steel radiator technical performance description and technical parameters 1, the main technical performance parameters 1.1 technology performance parameters 1.1.1, Material: Body Material selection δ = 2.5 cold rolled carbon steel plate steel radiator performance using meets GB / T8163-1999 low pressure fluid conveying pipe provisions, GB / T3091-2001 finishing carbon steel pipe. A variety of pipe wall thickness are 1.5mm. Threaded pipe fittings used in line with GB / T7306.1-2000 sealed tube threaded cylindrical thread regulations. 1.1.2 Working medium: circulating water PH value 7-9. 1.1.3 heating water temperature: Heating temperature 70-95 ℃ 1.1.4 Working pressure: ≤1.0MPa; test pressure: ≤1.5MPa; 1.1.5, surface coating and internal corrosion treatment to ensure that each group of radiator heating chip the surface is smooth and glossy, durable corrosion, phosphate, electrophoresis, resin electrostatic spraying, high temperature baking, coating the surface smooth, uniform color, after a high temperature of 200 ° C curing, the film adhesion, good impact resistance. Radiator embalmed within areas: internal corrosion is very important, because the current water quality due to heating systems and equipment reasons uneven, more advanced anti-corrosion technology selectable Nano waterborne anti-corrosion coating. 1.1.6 Quality Inspection radiator accordance with corporate standards for products manufactured before strict quality inspection. After completion of the welding radiator and front groups were conducted by spraying pressure test, the test pressure ≤1.5Mpa, when the pressure test, stop gas regulator 2min, radiator itself does not take bubble: When hydraulic pressure test, water regulator 2min , radiator does not leak. Paint adhesion to 1-3, after the film struck by the hammer, no cracks, wrinkles and spalling. 1.1.7 Test Methods gauges and special measuring tools to check the radiator dimensions and tolerances. Welding quality, coating quality visual conduct. Film heat resistance test methods: by GB / T1735-1979 conduct. Film impact resistance test method: According to GB / T1732-1993 conduct. Resistant paint adhesion test methods: by GB / T1720-1979 conduct. Radiator pressure test, the application-specific test rig, pneumatic or hydraulic test test pressure accuracy is not less than 1.5, the range of not more than 2.0Mpa. Screw threaded plug should be used for testing. Radiator according to the provisions GB / T13754 were tested. 1.1.8, marking, packaging, transportation, storage products clearly mark the location of the product name, specifications, name and address, the implementation of the standard number, production date. Adopted within the corrugated packaging radiator or other air cushion packaging to ensure product is not deformed during handling, does not damage the quality of the package of measures. Product transportation should be gently, to avoid the bump and other heavy compression, transportation should be rain, sun protection measures. 1.1.9, color standards should be based on the needs of users by color coating production color (white). 1.1.10, the amount of heat dissipation heat is water under standard conditions the water temperature is 95 ° C temperature 70 ° C, room temperature 18 ° C, the measured value is calculated temperature difference △ T = 64.5 ° C when. (Heat output in accordance with international regulations allow standard deviation ≤3% range). Single column radiator heat output in line with the minimum technical parameters specified in the table. 1.2 Device Performance Specifications Performance Specifications steel radiator 1.3 1.3.1 Mechanical technical performance radiator for hanging, appearance, generous. 1.3.2 Laser welding using the advanced automatic control of welding technology, single-column radiator weld not more than two, uniform welds, firm, smooth, no cracks, holes, welding slag and other defects. Import and export of the same caliber 1.3.3 radiator, and easy to install. 1.3.4 structural dimensions and geometric tolerances radiator structural dimensions and geometric tolerances: Interface center distance ± 2.0mm, height ± 3.0mm, the width of ± 1.0mm, ipsilateral and export flatness ≤3.0mm, import and export of the plane with the center Line verticality ≤2.0mm. 2. Scope of supply Scope of supply: radiator hanging GZ80 × 50, GZ60 × 90 (recommended) (equipped with a release valve and accessories) 3, the service life (concrete shape to be determined, it is recommended Manufacturer: Qingdao Ruihua special radiator ) body 5 year product warranty, consumable parts (release valve) are excluded. Ruihua steel radiators made of high quality carbon steel, one of the titles steel (imported raw materials) ultrafine nano-corrosion materials, vacuum filling evenly unlimited corrosion anti-corrosion coating; imports of polyester UV full vegetarian meal, automatic electrostatic spray stronger adhesion, the surface of the bright lights; after several 100% tightness pressure testing, strong pressure. Working pressure 1.2mpa. Features: two from the European pillar shape design simple, elegant and classic; thermal stability, suitable for a variety of heating, water and systems. Suitable for installation in the living room and bedrooms, den and kitchen areas. Using high quality raw materials made of one-piece overall titles, no grinding, impeccable quality, superior safety performance, materials with smooth surface. Wall structure fine and uniform. Pressure resistance, and not leak and so on. Brand Ruihua steel radiator radiator system price and offer price for VW psychological level. Its basic material is selected high-quality steel pipe, pipe after cutting, stamping, welding, grinding, electrophoresis, powder coating, anti-corrosion treatment and other complex process dozens of strict processing. Is composed of multiple titles with welded into one steel radiator. Radiator Co., Ltd. Qingdao Estuary price _ ___ steel radiator steel radiator Qingdao
