 Expansion Tube Introduction

Expansion tube, also known as an expansion tube, has two items with the same name. One is an oil expansion tube, and the other is an installation screw expansion tube, also known as a plastic expansion screw. Here, we are introducing the plastic expansion tube used for installation. Due to different dialects and habits in different regions, the so-called southern accents and northern tones, the expansion tube is commonly known as: swelling tube, swelling plug, swelling glue particle, wall plug, plastic anchor bolt, and many other names. The expansion tube should have existed before the expansion screw, evolving from the basic of wood plugs to plastic material expansion plugs. After the test of time and the environment, the performance of the ring-speed expansion tube is far superior to that of wood plugs. First, it can reduce the amplitude of cold shrinkage and thermal expansion, and it also outperforms wood in anti-aging effects. It is also good in force and convenient and standard in size. It can play the greatest tightening force for a long time in special environments such as insulation and water (humidity). Therefore, it has won the praise of a wide range of users. The use of expansion tube: used to tighten the connection and installation of various small and medium-sized hanging items. It can be used indoors and outdoors. Avoid using for heavy objects and heavy machinery, to avoid unnecessary losses.Expansion tube accessories: Generally, use of self-tapping screws with various head types, such as: countersunk self-tapping screws, round head self-tapping screws, large flat head self-tapping screws, external hexagonal and internal hexagonal self-tapping screws, double-head screws, etc. (Peripheral accessories: gaskets, screw caps, gaskets, hooks, etc.) Avoid using quick-locking screws (sharp wood screws) to avoid cutting the expansion tube body when the screw is forced in. It is recommended to use hardened self-tapping screws for installation to achieve the best friction force and the best tightening effect. The raw material of the expansion tube is generally soft HDPE (high-density polyethylene).
