Anti-static PTFE/PFA steel pipe

Anti-static PTFE-lined Steel Pipe is a specialized type of pipeline designed to transport corrosive or high-purity substances while minimizing the risk of static electricity buildup. This type of pipe combines the excellent chemical resistance and non-stick properties of PTFE (Polytetrafluoroethylene) with the mechanical strength of steel, and it incorporates anti-static properties to ensure safety in applications involving flammable or explosive materials.Key FeaturesAnti-static PropertiesSpecial additives in the PTFE lining reduce static electricity buildup during fluid transportation, making it suitable for handling flammable or volatile substances.Ensures safe operation in explosive environments by dissipating static charges.Chemical ResistancePTFE is highly resistant to a wide range of chemicals, including strong acids, alkalis, and organic solvents.Ideal for use in industries dealing with aggressive chemical substances.High Temperature ResistanceCapable of withstanding high temperatures, typically up to 260°C (500°F), depending on operating conditions.Durability and StrengthThe steel shell provides excellent mechanical strength, allowing the pipe to handle high-pressure applications.Resistant to mechanical impact and deformation.Smooth Inner SurfaceThe PTFE lining ensures a low friction coefficient, promoting efficient fluid flow and preventing material buildup.ApplicationsChemical and Petrochemical IndustriesUsed for transporting corrosive chemicals like acids, alkalis, and solvents.Suitable for explosive or volatile environments due to its anti-static properties.Pharmaceutical and Food ProcessingEnsures hygienic transportation of high-purity fluids.Non-reactive inner lining preserves the quality of transported substances.Semiconductor IndustryHandles ultra-pure chemicals required for wafer production and etching processes.Oil and Gas IndustryUsed in pipelines where the risk of static electricity ignition is high.Water Treatment PlantsIdeal for handling aggressive media like chlorine, sulfuric acid, and other water treatment chemicals.AdvantagesEnhanced safety in hazardous environments.Long service life with minimal maintenance.Customizable sizes, pressure ratings, and connection types to meet project-specific requirements.If you need additional information, such as technical specifications or implementation guidelines, feel free to ask!

Spiral Welded Steel Pipe

Spiral Welded Steel Pipe (SSAW) Introduction1. Product DefinitionSpiral welded steel pipe is a type of welded steel pipe made from steel strip coils. The strip is helically coiled under normal temperature and welded using double-sided submerged arc welding (SAW). The weld seam is spiral-shaped, making the pipe suitable for various pressure transmission and structural applications.2. Product FeaturesWide Range of Diameters: Suitable for producing large-diameter pipes using relatively narrow strip steel.High Strength and Pressure Resistance: The spiral seam distributes stress evenly.Cost-Effective: More economical than longitudinal welded pipes for large diameters.Good Welding Performance: Automatic double-sided SAW ensures stable welding quality.Custom Lengths Available: Pipes can be cut to specific lengths as required.3. Product SpecificationsItemSpecification RangeNominal DiameterDN200 - DN3000 (Φ219mm – Φ3000mm)Wall Thickness5mm – 30mm (customizable)Length6m – 18m (or customized)Steel GradeQ235B, Q345B, L245-L485 (API 5L), etc.Welding MethodDouble-sided Submerged Arc Welding (SAW)Surface TreatmentBlack, or anti-corrosion coatings (3PE, epoxy, etc.)4. Applicable StandardsStandard CodeStandard NameSY/T 5037Spiral Submerged Arc Welded Steel Pipe for Non-Pressure FluidsGB/T 9711Steel Pipe for Pipeline Transportation SystemsAPI 5LLine Pipe Specification (American Petroleum Institute)EN 10219Cold Formed Structural Hollow Sections (EU Standard)ISO 3183International Standard for Steel Line Pipes5. Main Applications✅ Pipeline Transmission:Long-distance transportation of oil and natural gasWater supply and drainage systemsDistrict heating pipelinesIndustrial fluid transmission (chemicals, pharmaceuticals, wastewater, etc.)✅ Structural Uses:Steel structures in buildings and bridgesPiling pipes for ports, piers, foundationsSupport pipes for tunnels and underground projects✅ Other Uses:Outer protection pipes for anti-corrosion and thermal insulation systemsSteel casing and sleeve pipes6. Common Anti-Corrosion Coatings3PE (Three-layer Polyethylene Coating): Ideal for underground or submerged pipelines.Epoxy Coal Tar Coating: Common in drainage, sewage, and municipal water supply systems.FBE (Fusion Bonded Epoxy): Excellent adhesion and corrosion resistance.Hot-dip Galvanizing: Suitable for environments with high oxidation requirements.
