Expansion pipe introduction

Expansion nail pipe first of all, there are two items with the same name called expansion nail pipe, one is oil expansion nail pipe, the other is expansion nail pipe for installing screws, and the other is called (plastic expansion screws) here, what we introduced is that it is the plastic expansion tube nail pipe used for installation. Based on the different local dialects and custom names, the so-called South-North tone, therefore, the expansion is nail pipe, commonly known as: nail pipe, rubber plug, expansion colloidal particle, wall plugs, plastic anchor bolt and other names. Expansion pipe it should be said that there were expansion screws before, which evolved from the foundation of wooden plug to the plastic material expansion plug. After the test of time and environment, the performance of Huanjie expansion pipe is far better than that of wooden plug, the first is to reduce the range of cold shrinkage and thermal expansion, which is better than wood material in anti-aging effect, and has good stress, and is convenient and standard with matching size. The maximum tightening force can be exerted for a long time in special environments such as insulation and water (humidity). Therefore, it has won the popularity of the vast number of users. The use of expansion pipe: it is used to fasten the connection and installation of various small and medium-sized pendant items. Can be used indoors and outdoors. Avoid lifting heavy objects and heavy equipment objects, so as to avoid unnecessary losses. Expansion pipe matching: Generally, the head type of self-tapping screws is not limited, such as countersunk self-tapping screws, Round Head self-tapping screws, large flat head self-tapping screws, outer hexagon socket head self-tapping screws, double-end screw, etc. (peripheral accessories: gasket, screws lid, rubber gasket, Hook, etc.) avoid using fast teeth (relatively sharp wood screw) in order to prevent the screw screw from cutting off the expansion pipe body when forced. It is recommended to install and use the self-tapping screws to exert the best friction force and achieve the best fastening effect. Expansion pipe of the raw materials, generally expansion pipe use soft rubber HDPE (polyethylene (polyethylene), referred to as PE) is a thermoplastic resin prepared by ethylene polymerization. Industrially, it also includes the copolymer of ethylene and a small amount of α-olefin.
