Regarding flange protective sleeves

Flange guards are available in various materials depending on the operating conditions: PTFE, PVC, polypropylene, stainless steel, carbon steel, and so on. The specific differences are detailed in the table below: Model, Applicable Conditions, Structural Description, Performance Description. PTFE: Performs well both indoors and outdoors; the front part provides splash protection, with an inner layer of 0.35 MM thick PTFE transparent film and an outer layer of PVC film; the splash protection elements at both ends are made of PTFE-treated fabric, while the mounting connectors are made of strong PTFE ropes. It is manufactured using imported three-thread embedding machines and high-strength PTFE sutures. Equipped with leak warning strips that are transparent, allowing for immediate detection of leaks; these strips also serve as a warning mechanism. It is flame-retardant, with a suitable operating temperature range of -40°C to 250°C. It resists ultraviolet rays, enabling a long service life. It is resistant to oil stains, most chemical corrosions, and water penetration. It is washable and reusable; the PVC transparent material performs well both indoors and outdoors. The splash guard on the front side is made of transparent PVC fabric, while the splash guards at the ends are made of coated polyester fabric that has been refined, with a PTFE coating applied to it. The mounting connectors are made of high-strength polypropylene polyester ropes, and it is manufactured using imported plastic clamping machines as well as high-strength PTFE sutures. Equipped with leak warning strips that are transparent, allowing for immediate detection of leaks; these strips also serve as a warning mechanism. It has certain flame-retardant properties, and can be used within a temperature range of -25°C to 75°C. It is resistant to ultraviolet rays, with a service life of over 1 year. It resists oil stains and most chemical corrosions, boasts excellent mechanical and electrical properties, high resistance to acids and alkalis, and good chemical stability. It is waterproof and reusable. Polypropylene performs well in indoor environments. The splash guards on the front are made of polypropylene (PP) refined fabric, while those at both ends are also made of polypropylene (PP) refined fabric. The mounting connectors are made of high-strength polypropylene (PP) ropes. It is manufactured using imported three-thread embedding machines, along with high-strength PTFE sewing threads. Resists ultraviolet rays; service life of 2 years. Resists most chemical corrosions; operating temperature range: -15°C to 65°C. Performs well both indoors and outdoors in stainless steel applications. The front splash barrier and the splash barriers at both ends are made of industrial-grade 304 stainless steel sheets. The mounting connectors are made of 304 stainless steel hook fixators. It is manufactured using a fully automatic custom seam welding and spot welding machine for one-piece processing, with subsequent treatment carried out using a semi-automatic custom grinding system. Easy to install; does not burn; operating temperature range: -200°C to 650°C. Resists various acids and alkalis, as well as atmospheric conditions, ultraviolet rays, and radioactive substances. High strength and impact resistance; suitable for high-pressure media. Reusable. Performs well both indoors and outdoors in carbon steel applications. The front splash barrier and the splash barriers at both ends are made of industrially cold-rolled sheets. The mounting connectors are stainless steel fixators. It is manufactured using a fully automatic custom seam welding and spot welding machine for one-piece processing, with subsequent treatment carried out using a semi-automatic custom grinding system. The final finishing is done using chemical coatings for corrosion protection. Easy to install; the main body does not burn; operating temperature range: -200°C to 250°C. Resists various acids and alkalis. High strength and impact resistance; suitable for high-pressure media

Currently, PVC material is used, and it is not only applied in the compressor area.
