In industrial production, Teflon braided hose is widely used in chemical industry, petroleum, aerospace, electric power, semiconductor and other fields due to its excellent corrosion resistance, high temperature resistance, high pressure resistance and other properties. This article will introduce in detail the production process of Teflon braided hose. From raw material preparation to finished product testing, each step reflects fine craftsmanship and strict quality control.
Production process
1. Raw material preparation
The production of Teflon braided hose first requires the preparation of three main materials: inner tube, braided layer and outer tube. The inner tube is usually made of polytetrafluoroethylene (PTFE), which is an ideal choice due to its resistance to high temperatures, acids and alkalis. The braided layer is made of stainless steel wire or other high-strength fibers, which are woven into a tough mesh structure through precision braiding equipment to provide strength and pressure resistance for the hose. The outer tube is made of stainless steel and other materials to protect the hose from the external environment.
2. Cutting and assembly
Cut the prepared raw materials to the required length. Then, the inner tube, braided layer and outer tube are put together in sequence to ensure a tight fit between the layers without gaps.
3. Knitting process
The assembled hose is placed in the braiding machine, and multiple braided wires are staggered and braided into a spiral braided layer through the up and down pulling motion of the machine. This step requires extreme precision and stability to ensure the uniformity and strength of the braid. During the weaving process, the braided threads need to be kept clean and loose or misplaced.
4. Suppression and Fusion
After braiding is completed, the hose is placed in a heating machine for pressing. The outer tube is melted by heating and tightly combined with the braided layer, thereby improving the pressure resistance and corrosion resistance of the hose. The temperature and time need to be strictly controlled during the pressing process to ensure that the outer tube and the braided layer are fully integrated, while avoiding overheating that may cause material deformation or damage.
5. Quality inspection
The completed Teflon braided hose needs to undergo strict quality inspection. The inspection process includes visual inspection, pressure test, leakage test and other links. The appearance inspection mainly checks whether the surface of the hose is smooth and flawless; the pressure test tests the pressure-bearing capacity of the hose by applying a certain pressure; the leakage test detects whether there is leakage in the hose by simulating actual usage scenarios. Only products that pass all tests and meet standard requirements can be officially put into the market.
The production process of Teflon braided hose is a complex and delicate process that requires strict process control and quality control. Through the selection of high-quality raw materials, fine processing and strict quality testing, Teflon braided hoses with excellent performance can be produced. These hoses play an important role in various fields and provide reliable piping solutions for industrial production.
