Overview
PTFE-lined anti-corrosion pipes have been used for many years, and the factors that directly affect their service life and performance stability are temperature, pressure, and medium. Quality materials and advanced manufacturing processes are the quality assurance of PTFE-lined products.
1. High use temperature: Under the condition of strong corrosive medium, it can meet the operating temperature range -60 °C ~ 200 °C, in which all chemical media can be satisfied.
2. Vacuum resistance: can be used under vacuum conditions. In chemical production, local vacuum conditions are often caused by cooling, longitudinal discharge, and asynchronous operation of pumps and valves.
3. High pressure resistance: It can withstand the use pressure of up to 3MPa within the temperature range.
4. Anti-penetration: The high-quality PTFE lining layer is processed by high-quality PTFE resin after advanced lining process, so that the product has superior anti-permeability.
5. The integral molding and sintering process lining solves the problem of steel-fluorine cold heat expansion and contraction, so that it can achieve synchronous expansion and contraction.
6. It adopts standardized size preparation, especially the pipelines and pipe fittings used in chemical pipelines have strong interchangeability, which provides great convenience for installation and spare parts.
Selection of steel pipes and flanges for lining PTFE pipes and pipe fittings
1. The pipeline adopts the national standard without steel pipes. Due to the process requirements, the effective diameter of the pipeline after lining is smaller than the nominal diameter of the steel pipe. The designer and the user determine the diameter of the steel pipe after carrying out the necessary effective flow standards;
2. Flange can be based on HG, GB, JB, ANSI, JIS, BS, DIN and other national standards, which can be forged or contracted. Flat welding flange. The sealing surfaces are all flat seal type. In order to facilitate the installation of the pipeline, the user can provide the flat welding ring movable flange.
