材料说明：
波纹管体：为了更持久的使用寿命，全部采用不锈钢304正材生产，支持各种光谱仪检测，假一赔十，厚度全部厚于同行业标准。
连接法兰：法兰全部采用山西正宗锻打材质，无论是强度还是密封性都是很好的材质，不要拿市面上的铸钢、钢板钢法兰来对比，没有任何可比性。
焊材：焊材全部采高于母材等级标准，让焊接点更加牢固。
限位耳板：耳板全部采用加大加厚尺寸生产，每个型号都可以与同行业同型号去一对一的对比，这就是所谓的没有对比就没有伤害。
限位螺杆：螺杆全部采用8.8级高强度镀锌，为100%确保产品的综合强度，不要与市面的4.8级来对比，无意义。
生产标准：淞江集团通过德国莱茵TUV认证，并且严格按照压力管道生产要求进行生产，让出厂的每一个DN65消防泵波纹伸缩节产品达到100%的合格。

DN65消防泵波纹伸缩节采用奥氏体不锈钢材料或按用户要求的材料制造，具有优良的柔软性，耐蚀性，耐高温性，耐高压性，在管路中补偿轴向位移，用以温度补偿和吸收振动、降低噪声、改变介质输送方向、消除管道间或管道与设备间的轴向位移等，DN65消防泵波纹伸缩节对有轴向位移的管道补偿尤为适用。
DN65消防泵波纹伸缩节属于一种补偿元件。利用其工作主体波纹管的有效伸缩变形，以吸收管线、导管、容器等由热胀冷缩等原因而产生的轴向变化，或补偿管线、导管、容器等的轴向位移；也可用于降噪减振。

Material description:

Bellows body: in order to prolong the service life, all of them are made of stainless steel 304 normal materials, and support the detection of various spectrometers. One false is compensated for ten, and the thickness is all thicker than that of the same industry standard.

Connecting flanges: all flanges are made of Shanxi authentic forged materials, which are good in strength and tightness. Do not compare them with cast steel, steel plate and steel flanges on the market. There is no comparability.

Welding materials: all welding materials shall be higher than the grade standard of base metal to make the welding point more firm.

Limit ear plate: all ear plates are produced by increasing the thickened size. Each model can be compared one-to-one with the same model in the same industry, which is the so-called no harm without comparison.

Limit screw: all screws are made of grade 8.8 high-strength galvanized to ensure 100% of the comprehensive strength of the product. It is meaningless to compare with grade 4.8 in the market.

Production standard: Songjiang group has passed the TUV certification of Rhine, Germany, and is produced in strict accordance with the production requirements of pressure pipeline, so that each DN65 fire pump corrugated expansion joint product can reach 100% qualification.

DN65 fire pump bellows expansion joint is made of austenitic stainless steel or materials required by users, with excellent flexibility, corrosion resistance, high temperature resistance and high pressure resistance. It can be connected in any direction in the pipeline to compensate for temperature, absorb vibration, reduce noise, change the direction of medium transmission, eliminate mechanical displacement between pipelines or between pipelines and equipment, etc. DN65 fire pump bellows expansion joint has displacement The flexible joints of various pumps and valves that vibrate are particularly suitable.

The DN65 fire pump corrugated expansion joint belongs to a compensation element. The effective expansion deformation of the bellows of its working body is used to absorb the dimensional changes of pipelines, conduits and containers caused by thermal expansion and cold contraction, or to compensate the axial, transverse and angular displacement of pipelines, conduits and containers. It can also be used for noise reduction and vibration reduction.
