Steel Lined PTFE Seamless Steel Pipe, Steel PTFE Composite Pipe
Carbon steel lined PTFE pipe fittings, flange connection at both ends, carbon steel lined PTFE pipe fittings, PTFE lined pipe PTFE lined pipe, PTFE lined pipe, PTFE lined pipe fittings, carbon steel pipe lined with PTFE detail The specifications, dimensions, and technical requirements can be produced according to customer requirements. The steel-fluorine composite pipe produced by our company adopts a new process. It is a new type of chemical pipe and device that is corrosion-resistant, temperature-resistant, non-scaling, not easy to grow microorganisms, and can ensure the purity of the conveying medium. Its life span exceeds stainless steel and the price is moderate. , Outstanding in all kinds of anti-corrosion pipe appliances. In recent years, steel-fluorine composite pipes have been widely used and have achieved satisfactory results and obvious economic effects. It has become an upgraded product of other steel-plastic composite pipes in our country. Steel-fluorine composite pipes are integrally molded lining products.
Its characteristics are as follows:
1. High operating temperature: Under conditions of strong corrosive media, it can meet the operating temperature range of -60℃～150℃. In this temperature range (except molten alkali metals, elemental fluorine and aromatic hydrocarbons), all chemical media can be met.
2. Vacuum resistance: within the range of -60℃～150℃, it can be used under vacuum conditions. In chemical production, partial vacuum is often caused by cooling, vertical discharge, and asynchronous operation of pumps and valves.
3. High pressure resistance: in the temperature range, it can withstand the pressure up to 3Mpa.
4. Anti-permeability: The selected resin is processed into a high-density, sufficient thickness PTFE lining layer through advanced lining technology, so that the product has superior anti-permeability.
5. The integral moulding and sintering process lining solves the problem of steel-fluorine cold and hot expansion and contraction, so that it can achieve synchronous expansion and contraction.
6. It adopts standardized size preparation, especially the pipes and pipe fittings used in chemical pipelines are highly interchangeable, which provides great convenience for installation and spare parts. Application range Diameter (DN): 25 mm (1) 250 mm (10 ) PTFE lining number: 21 mm 246 mm
