我公司专业生产销售声测管、螺杆空压机、高频焊机、精密汽车钢管、管板焊接。

套筒式声测管是声测管中比较早期的产品，它的原理很简单就是在底管上面焊接一个套筒，套筒的外径要比底管大，然后在把顶管插入套筒内，焊接密封，这就是套筒式声测管，图中的套筒式声测管是我公司自主研发的产品，他是在套筒外增加了PEG热缩塑料。热缩塑料内壁有密封胶，通过加热或紧紧地粘连在套筒连接处，这样就增加了套筒式声测管的密封性。是目前非常畅销的产品。 （图/文www.yxbohua.com）

Sleeve type acoustic pipe is acoustic comparison of early products tube, its principle is very simple in the bottom pipe is welded with a sleeve, sleeve diameter than the bottom tube, and then the pipe is inserted into the sleeve, sealing, which is sleeve type acoustic pipe, sleeve type acoustic diagram test tube is our own developed products, he is the increase in the PEG heat shrinkable plastic sleeve. Heat shrinkable plastic wall with a sealant, by heating or tightly adhesion at the connecting point of the sleeve, thus increasing the sleeve type acoustic sealing tube. Is currently very popular products.
