最新容器板附加值
Q245-Q345-Q370的区别
Q245R、Q345R铬钼合金钢牌号表示方法不变，用平均含C量和合金元素字母、压力容器“容”字的汉语拼音首位字母表示。
例如：15CrMo R GB713锅炉用钢板20gGB6654压力容器用钢板20R、16MnR15CrMo g、15CrMo R5、尺寸、重量及允许偏差5.1 尺寸范围由于锅炉和压力容器行业发展要求，钢板尺寸规格加大，轧机不断改造更新，引进宽厚板生产线，厚度范围3m m～200mm，钢板宽度加宽到4800mm。
5.2 尺寸、外形、重量及允许偏差尺寸、外形及允许偏差应符合G B/T709。
厚度偏差直接采用GB/T709－2006的B类偏差。
固定负偏差为0.3mm（B类）明确指出计算理论重量采用的厚度为钢板允许的最大厚度和最小厚度的算术平均值，钢的密度为7.85g/cm3。
与GB/T709－2006一致。
厚度范围：6～120mm最大宽度：3800mm 厚度负偏差－0.25mm计算理论重量的钢板厚度计算按厚度附加值。
修订项目新标准修订内容原标准6、牌号二个标准经过整合，淘汰落后牌号，纳入先进牌号。
6.1 合并一些牌号对二标准中按牌号成分和性能的要求，就高不就低的原则进行合并。
20g和20R合并后改为Q245R；16Mng、19Mng和16MnR合并后改为Q345R；15CrMo g和15C rMoR合并后改为15CrMo R。
6.2 淘汰15Mn VR、15MnVN R和22M ng15M nVR主要用厚度6～8mm 的多层包扎容器，强度波动较大、韧性偏低。
取消15Mn VR后，可以选用Q345R和370R。
15MnVN R钢板以前主要用于制造氧气球形储罐，现已被强度更高、韧性和焊接性更好的07MnCrM o钢板所取代。

The large number of tank sizes and types available makes it possible to select the pressure tank that best suits the application and system in question.Tank rangeGT-U (bladder)The pressure tank body is made of steel and is factory-pre-charged with nitrogen. All parts in contact with water are either made of stainless steel or coated for protection against corrosion.The replaceable bladder for tanks with a volume exceeding 60 litres is made of high-quality rubber material suitable for potable-water applications, such as booster systems, pressurisation and water hammer arresting.GT-H (diaphragm)The polypropylene liner combined with an FDA-approved high-grade butyl diaphragm makes up the water chamber. This is held against the tank wall with a steel clench ring.The brass air valve, sealed by a threaded O-ring valve cap, prevents air leaks.GT-D (double diaphragm)The diaphragm is a chlorine-resistant 100 % butyl diaphragm with a precision-moulded copolymer polypropylene liner for superior air and water separation.The diaphragm assembly is clenched together with a positive lock internal clench ring which contains drawdown water in a pre-charged air atmosphere, thus providing separation between the diaphragm and tank wall. This "air buffer" means less problems with condensation.The air chamber is sealed with a fixed O-ring and closedcell foam.GT-DF (double diaphragm with FlowThru)The FlowThru connection diverts system water into, and more importantly out of the tank, while the pump is running. This constant flushing ensures that the water inthe tank remains fresh and eliminates the risk of stagnant water during normal system operation.See figs 2 and 3.GT-C (composite tank)The GT-C pressure tank is a lightweight pressure tank.The diaphragm is a chlorine-resistant 100 % butyl diaphragm with a precision-moulded copolymer polypropylene liner for superior air and water separation. This design allows each tank size to have a properly sized water chamber matched to the drawdown performance of that tank.GT-CA (composite tank with air volume)The water is forced through the air injector which saturates the water with air. The air-saturated water isthen held in the composite tank for a period of time to allow the air to be liberated from the water. The periodof time (days/weeks) depends on the level of contamination. This process also removes unwantedgases such as sulphur-containing gases from the water. When a certain level is reached, a vent opens and allowsthe unwanted gases to escape.5GT-CF (composite tank with FlowThru)The FlowThru connection diverts system water into, and more importantly out of the tank, while the pump is running. This constant flushing ensures that the water in the tank remains fresh and eliminates the risk of stagnant water during normal system operation.See figs 2 and 3.Fig. 2 Illustration of the FlowThru function Fig. 3 Illustration of the FlowThru principle T M 0 4 5 4 2 2 3 3 0 9 T M 0 4 5 4 2 4 3 3 0967SizingTank sizes not exceeding 450 litresFor tank sizes not exceeding 450 litres, use the diagram below in order to choose the optimum tank size.All you need to know is the cut-in pressure and the flow.The diagram below is based on the following values:•Differential pressure: 1 bar.•Number of starts/stops per hour: 20.•Constant for tank pre-charge pressure: 0.9.Tank sizes exceeding 450 litresTank sizes exceeding 450 litres should be calculated from the formula below.Fig. 4 Calculation of volumeLegendFig. 5 Tank size in relation to cut-in pressure and flowT M 04 5567 3409V 0 =1000 x Q s x (p 1 + 1) x (p 2 + 1)4 x N x (p 0 + 1) x (p 2 -

These tanks can be incorporated in an expansion system in a tiny household or a large multi-storey building.Typical applications:•domestic-heating and chilled-water systems •commercial-building heating and chilled-water systems•industrial-heating and chilled-water systems.GT-HR tanks can be used with any Grundfos pump. Tank rangeThe GT-HR tanks are available in sizes ranging from8to1000 litres and are suitable for vertical installation. The tanks have a non-replaceable diaphragm that is pre-charged with nitrogen (1.5 bar).The tanks have a non-toxic butyl rubber diaphragm, dividing the tank chamber into two compartments. The upper compartment contains compressed nitrogen. The lower compartment has a liner of polypropylene (PP) and is filled with water from the pump. SizingThe required tank volume can be calculated from the formula below:If the necessary information required to calculate the tank according to the formula is not available, the sizing of the tank can be based on heat input to the installation and maximum system pressure.Pre-conditionsHeating systems: flat radiators, specific water volume of 11.3 l/kW, flow-pipe temperature of 70 °C and return-pipe temperature of 50 °C.Grundfos recommendation:•Set the tank pre-charge pressure to at least 0.2 bar above the static pressure of the heating system.•The tank pre-charge pressure should not be lower than 1 bar.Sizing example:A heating system has a heat input of 160 kW, the maximum system pressure is 6 bar, and the heating system will be pre-charged by 3 bar.Use the column for 6 bar maximum system pressure. The nearest value above 160 kW is 170 kW. This corresponds to a tank size of 140 litres.V e =(0.07 x t - 2.5) x (p s + 1)x V [litre] 100 x (p s - p e)V e Tank volume [litres]t Maximum temperature in system [°C] p s Maximum system pressure [bar](safety valve pressure)p e Pre-charge pressure [bar]V Total volume of water in system [litres]Maximum system pressure[bar]6Pre-charge pressure [bar]3Tank size [l] Heat input [kW]48812161827254435605010080120100170140250200310250370300490400620500740600990800123010001617GT-HR, 6 barVertical installationDimensions, weights and product numbersFig. 14 Dimensional sketchesT M 03 1681 2809 - T M 03 1682 2809 - T M 03 1694 2809Tank typeSize [l]Dimensions [mm]Gross weight[kg]Product numbersD H C GT-HR-8 PN 6 G 3/4 V 8272233G 3/4 1.996573376GT-HR-12 PN 6 G 3/4 V 12272315G 3/4 2.696573377GT-HR-18 PN 6 G 3/4 V 18308360G 3/4 3.596573378GT-HR-24 PN 6 G 3/4 V 24308480G 3/4 4.696573390GT-HR-35 PN 6 G 3/4 V 35376465G 3/4 5.496573393GT-HR-50 PN 6 R 3/4 V 50441495R 3/412.596573395GT-HR-80 PN 6 R 1 V 80512570R 117.096573396GT-HR-100 PN 6 R 1 V 100512680R 120.596573397GT-HR-140 PN 6 R 1 V 140512890R 128.696573398GT-HR-200 PN 6 R 1 V 200634785R 136.796573399GT-HR-250 PN 6 R 1 V 250634915R 145.096573400GT-HR-300 PN 6 R 1 V 3006341085R 152.096573401GT-HR-400 PN 6 R 1 V 4007401075R 165.096573403GT-HR-500 PN 6 R 1 V 5007401295R 179.096573404GT-HR-600 PN 6 R 1 V 6007401530R 185.096573405GT-HR-800 PN 6 R 1 V 8007401990R 110396573407GT-HR-1000 PN 6 R 1 V10007402430R 1120965734088 to 25 litres35 to 140 litres18WebCAPSWebCAPS is a Web -based C omputer A ided P roduct S election program available on .WebCAPS contains detailed information on more than 185,000 Grundfos products in more than 20 languages.In WebCAPS, all information is divided into six sections:•Catalogue •Literature •Service •Sizing •Replacement •CAD drawings..ServiceThis section contains an easy-to-use interactive service catalogue.
