伸缩接头具有耐高压、高温的特点，防震型伸缩接头，是由SUS304不锈钢双层钢板结构成型，具有较低的弹性系数及耐高压、高温的特点，很 适用于热媒管路等高温流体的热膨胀吸收，并能提供较长的伸缩寿命。我公司在设计这类减震接头时以“弹性系数小”为考虑点，形象讲就是波纹体要比较软，越软效果就越好。此外，在设计时候还需要考虑到承压时不能失稳。
 伸缩接头连接伸缩管或波纹管的温度变化较大，一种保护措施。如热膨胀和收缩的固体，该变异的长度虽然不大， 但防止出现变形的对象是有一个巨大的力量。例如，截面积为1厘米2长度为1米的钢条，当温度40℃长度截面积，延伸大约只有0.0005米。如果你不让它伸展，将限制其对象产生104牛顿的力。大截面积，更大的力量。要在工程技术， 这个由热膨胀产生的力量，应该首先考虑并采取必要的措施。例如，钢桥面必需装置一个活动结束支持关于自由的伸展桥梁。

Expansion joints with high pressure, high temperature characteristics, the shock expansion joints, SUS304 stainless steel double steel structure forming, has a low coefficient of elasticity and high pressure, high temperature characteristics, is perfect for high-temperature fluids such as heat medium pipingthermal expansion absorption, and can provide a longer telescopic life. Company in the design of this type of shock absorber connector to the small coefficient of elasticity to consider the point, the image speak corrugated body is quite soft, the softer the better the effect will be. In addition, at design time also need to consider when not to pressure instability.
 Expansion joints to connect the change in temperature of the extension tube or bellows, a measure of protection. Such as thermal expansion and contraction of the solid, the length of the variation, but to prevent the deformed object is a tremendous power. For example, the cross-sectional area of one cm length of 1 m of steel bars, when the temperature is 40 ℃ the length of cross-sectional area, an extension of only about 0.0005 m. If you do not let it stretch, will limit its objects to produce a force of 104 Newton. Large cross-sectional area, greater strength. In engineering technology, the power generated by the thermal expansion, should first consider and adopt the necessary measures. For example, the end of an activity of the necessary devices of the steel deck to support the stretch on the freedom of the bridge.
