制药用卫生级米勒不锈钢真空大小头价格

异径管(大小头)是用于管道变径处的一种管件。通常采用的成形工艺为缩径压制、扩径压制或缩径加扩径压制，对某些规格的异径管也可采用冲压成形。异径管的圆度不应大于相应端外径的1%，且允许偏差为±3mm。异径管的材质执行SY/T5037、GB/T9711、GB/T8163、美标ASTM A106/A53 GRB，API 5L、APT5CT、ASTM A105、ASTM A234、ASTM A106、DIN德国标准及客户要求标准

1、当管道中流体的流量有变化时,比如增大或减少,流速要求变化不大时,均需采用异径管.

2、在泵的进口,为了防止汽蚀，需要采用异径管.

3、与仪表,如流量计、调节阀的接头处,为了与仪表的接头配合,也需采用异径管。

真空大小头又称异径管是化工管件之一，用于两种不同管径的连接。又分为同心大小头和偏心大小头。先由圆钢经过高温锻打做成相应规格的毛坯，质检合格后经过CNC数控机床精车而成的一体件，通过氦气检漏等一系列检验，确定除合格产品。真空大小头尺寸精确，表面处理精细，密闭性能良好。广泛用于航天、航空、石油、石化、液化气、医药、食品、电力、半导体、太阳能、机械设备配套、电子工业等产品领域。

Reducing pipe (size head) is a kind of pipe fitting used for pipe diameter change. Generally, the forming process is necking pressing, expanding pressing or necking plus expanding pressing, and stamping forming can also be used for reducing pipe of some specifications. The roundness of the reducing pipe shall not be greater than 1% of the outer diameter of the corresponding end, and the permissible deviation is ± 3 mm. SY/T5037, GB/T9711, GB/T8163, n Standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements standards 1. When the flow rate in the pipeline changes, for example, increase or decrease, flow rate requirements change little, all need to use reducing pipe. 2. In the inlet of the pump, reducing pipe is needed to prevent cavitation. 3, with the instrument, such as flowmeter, control valve joints, in order to cooperate with the instrument joints, but also the use of reducing pipe. Vacuum Size Head, also known as reducing pipe is one of the chemical pipe fittings, used for the connection of two different pipe diameters. Also divided into concentric size head and eccentric size head. The round steel is made into the corresponding blank by high temperature forging, and the qualified product is determined through a series of tests, such as helium leak detection. The vacuum size head size is accurate, the surface treatment is fine, the airtight performance is good. Widely used in aerospace, aviation, petroleum, petrochemical, liquefied petroleum gas, medicine, food, electric power, semiconductor, solar energy, mechanical equipment, electronic industry and other product fields.
