In fact, many customers do not know the pump tube, the pump tube we do a simple overview: the ground pump tube wear-resistant tube, the other pump tube is also divided into high-pressure pump tube and low-pressure pump tube; there is a point that can be explained in the general manufacturer The low pressure is only the difference between the flanges at both ends, the high pressure flange is 157mm and the low pressure is 148mm. What is the difference between the pump tube and the pump tube? Different company products are definitely different. The production technology and parameters are different, and the standards are different.

1. The pump tube is divided according to the pipe material and can be divided into straight seam, fluid pipe and seamless pipe! This is the place to confuse people. When it comes to fluid pipes, what is the concept of fluid pipes? Fluid tubes are typically tubes that are dedicated to fluid media or flow delivery. Generally used in petroleum, chemical, and boilers. Concrete is also a type of flow transport, as the name suggests fluid tubes are more suitable for pump tube production. It is also said that the fluid tubes are processed in a seamless tube, and in the past the fluid tubes were all made using seamless tubes. In addition, whether it is a straight seam pipe or a seamless pipe must be qualified, it can not be a fake product of a small manufacturer, otherwise it will burst. .

2, according to the use of the point is actually not the same, there are many types of flanges, mostly to distinguish the pump tube first on the flange, the flange is thick, the height is not the same, there is a set of welding, There is also a direct connection to the flange (the above mentioned flange is the pipe clamp at both ends of the manifold). The thickness of the flange is not the same, the height is not the same, and the welding surface is definitely different; that is, the pipe to be welded is also different, and the most customers should be distinguished. Of course, the price of the flange is definitely not the same, which means that the price of the pump tube is not the same!

3, then when the customer purchases goods, in order to avoid problems with the goods. Try to say the outer diameter of the tube. We often use 133mm and 140mm; but these two models are collectively referred to as DN125.

Concrete pump tube

If the pump tube is subjected to conventional welding operations, many of the pipes whose inner walls have been treated with corrosion protection will be destroyed. Therefore, the specification stipulates that galvanized pipes, plastic-lined steel pipes, steel-plastic composite pipes, etc. shall not be welded or flanged, otherwise secondary treatment is required. His connection has a unique flexibility, which makes the pipeline resistant to vibration, shrinkage and expansion.

Ground pump tube

According to the scope of use, the pump tube is divided into two types: a tow pump tube and a ground pump tube. The tow pump tube includes a boom tube, a hinge elbow, a reducer tube and a curved tube, and is cast.
