产品介绍

Purpose of plastic expansion pipe:

It is used to fasten the connection and installation of various small hanging articles. It can be used indoors and outdoors. It shall not be used for lifting heavy objects and heavy equipment to avoid unnecessary losses.

Installation of plastic expansion pipe:

Generally, self tapping screws are required, and the head type is not limited, such as: countersunk head self tapping screws, round head self tapping screws, large flat head self tapping screws, external hexagon and internal hexagon self tapping screws, double head screws, etc. (peripheral accessories: gaskets, screw covers, rubber rings, hooks, etc.). Avoid using fast teeth (sharper wood screws) to prevent the screws from cutting the expansion pipe. It is recommended to install and use hard self tapping screws to exert the best friction and achieve the best fastening effect.

Raw materials of plastic expansion pipe:

Generally, the flexible rubber HDPE (polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. Industrially, it also includes ethylene and a small amount of α- Copolymers of olefins. Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low temperature resistance, good chemical stability, and can resist most acid and alkali corrosion. It is insoluble in general solvents at normal temperature, with small water absorption and excellent electrical insulation performance. Or PA6 and PA66 (cotton fiber is the trade name of polyamide fiber, also known as nylon, and the English name is polyamide (PA for short). Its basic composition is aliphatic polyamide connected by amide bond - [nhco]) Etc. It is characterized by good toughness, not easy to crack and strong bearing capacity. Among them, nylon is the most widely used variety among the five engineering plastics.

Style and classification of expansion pipe:

There are two kinds of expansion pipe commonly used in the expansion housekeeper gauge: straight through expansion pipe and fish type expansion pipe. With the expansion and demand of the market application field, the style of expansion pipe is more and more wide, and its function is more obvious and powerful. The professional models include expansion pipes (aircraft type expansion pipes) for ceiling gypsum board, and multi-functional binding expansion pipes for hollow walls and hollow bricks. The expansion pipe sizes are m4-m16, and the diameter and length are from 20mm to 160mm. The models include straight expansion pipe, fish type expansion pipe, cone type expansion pipe, flange expansion pipe, straight extension expansion pipe, knot type expansion pipe, American type expansion pipe, tooth type expansion pipe, driven rapid expansion pipe, double fin fish type expansion pipe, nylon expansion pipe, etc.
