Material: Made of PE material.
Color: White, Grey
Usage:
Used for fastening the connection and installation of various small and medium - sized hanging items. It can be used indoors and outdoors. Avoid using it to hang heavy objects and heavy machinery to prevent unnecessary losses.
Installation of plastic expansion pipes: Generally, self - tapping screws are required, and the head type is not limited, such as countersunk self - tapping screws, round - head self - tapping screws, large flat - head self - tapping screws, external and internal hexagon self - tapping screws, double - ended screws, etc. (Peripheral accessories: washers, screw caps, rubber rings, hooks, etc.) Avoid using fast - threading screws (wood screws with sharp threads) to prevent the expansion pipe body from being cut off when the screw is forced in. It is recommended to install with hardened self - tapping screws to achieve good friction and fastening effect.
Raw materials:
General expansion pipes are made of soft rubber HDPE (polyethylene, abbreviated as PE), which is a thermoplastic resin obtained by the polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α - olefins. Polyethylene is odorless, non - toxic, feels like wax, has excellent low - temperature resistance, good chemical stability, and can resist the erosion of most acids and alkalis. It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation properties. Or PA6, PA66 (Nylon is the commercial name of polyamide fiber, also known as Nylon). The English name is Polyamide (abbreviated as PA), and its basic components are aliphatic polyamides connected by amide bonds - [NHCO] -. These materials are injection - molded. They are characterized by good toughness, not easy to break, and strong load - bearing capacity. Among them, nylon materials are one of the five major engineering plastics used.
Styles and classifications:
The commonly used expansion pipes in the industry standard are generally straight - through expansion pipes and fish - shaped expansion pipes. With the expansion of the market application fields and demands, the styles of expansion pipes are becoming more diverse, and their functions are more obvious and powerful. Huanjie's professional styles include ceiling gypsum - dedicated expansion pipes (airplane - type expansion pipes), and multi - functional knotted expansion pipes for air - wall hollow bricks. Huanjie expansion pipes have diameters from M4 - M16 and lengths from 20mm to 160mm. Styles include straight - through expansion pipes, fish - shaped expansion pipes, conical expansion pipes, flange expansion pipes, straight - through extended expansion pipes, knotted expansion pipes, American - style expansion pipes, toothed expansion pipes, push - in quick - expansion pipes, double - wing fish - shaped expansion pipes, nylon expansion pipes, etc.
