Product Description Product Display HYT 202 Stainless Steel PipeEconomical austenitic stainless steel pipe, showing superior performance in mildly corrosive environments. HYT 202 pipes are made using precision cold rolling technology, with high surface finish, suitable for civil fields such as interior decoration, furniture manufacturing, and food processing equipment. While maintaining basic anti-rust properties, it provides a more cost-effective solution. HYT 304/304L Stainless Steel PipeA model of industrial-grade general-purpose stainless steel pipes. The HYT 304 series has excellent formability and welding performance, and the L-type low-carbon formula effectively prevents the precipitation of welding carbides. The solution-treated pipe body is widely recognized in chemical equipment, heat exchange systems, building curtain walls and other fields, and its surface passivation film can resist the erosion of most organic and inorganic acids. HYT 310/310S Stainless Steel PipeSpecialized pipe for high-temperature conditions. The alloy ratio with a chromium content of up to 25% gives the HYT 310 series excellent antioxidant ability and maintains stable performance in a high temperature environment of 1150oC. It is particularly suitable for thermal systems such as heat treatment equipment, industrial kiln components, and radiation tubes. The S-type ultra-low carbon version significantly improves the ability to resist intergranular corrosion. HYT 316/316L Stainless Steel PipeThe benchmark for marine-grade corrosion-resistant pipes. The HYT 316 series with 2-3% molybdenum elements shows super strong pitting resistance in chloride environments. The L-type low-carbon version is specially optimized for welding processes and is the preferred pipe in the fields of shipbuilding, seawater desalination, coastal chemical industry, etc. Its pitting corrosion equivalent PREN value is above 26. HYT 321 Stainless Steel PipeTitanium-stabilized austenitic pipe. By adding titanium elements to effectively control the precipitation of chromium carbide, HYT 321 pipes are particularly suitable for high-temperature operating environments in the range of 400-900oC. Widely used in thermal circulation systems such as aircraft engine exhaust pipes and petrochemical cracking units, its intergranular corrosion resistance reaches the highest level of ASTM A312 standard. HYT 410 Stainless Steel PipeMartensitic hardening practical pipe. HYT 410 can obtain a hardness value of up to 40HRC through heat treatment. On the premise of ensuring basic corrosion resistance, it is particularly suitable for wear-resistant parts, pump valve components, tool manufacturing and other fields. The inner and outer surfaces of the polished pipe body can reach Ra0.8μm finish. HYT 904L Stainless Steel PipeSuper austenitic special pipe. The high alloy formula with a nickel content of 25% makes HYT 904L perform well in strong corrosive media such as concentrated sulfuric acid and phosphoric acid. The microstructure uniformity is ensured by the triple annealing process, and it is specially designed for harsh environments such as pharmaceutical equipment, chemical reactors, and flue gas desulfurization systems. HYT Duplex Steel 2205 PipeA new generation of high-strength corrosion-resistant pipes. The austenite-ferrite duplex structure makes HYT 2205 have both high strength (yield strength ≥ 450MPa) and excellent stress corrosion resistance. It is particularly suitable for submarine pipelines, oil and gas transportation, papermaking cooking equipment and other fields. Its chloride ion corrosion resistance is more than 3 times that of ordinary 316L. HYT Duplex Steel 2507 PipeThe pinnacle of super duplex stainless steel pipes. HYT 2507 with a PREN value of more than 40 adopts a 25Cr-7Ni-4Mo alloy system and exhibits excellent performance in high temperature and high pressure corrosion environments. The GTAW welding process ensures phase balance in the weld zone, which is the ultimate solution for seawater hydraulic systems, FGD scrubbers, and chemical high-pressure pipelines. FAQQ: How to choose the applicable scenarios of different grades (such as 304L vs 316L)?A:304/304L: general purpose, suitable for mildly corrosive environments such as food processing and building curtain walls316/316L: contains molybdenum to resist chloride ion corrosion, recommended for marine engineering and chemical equipmentDuplex steel 2205/2507: high strength and corrosion resistance, suitable for submarine pipelines and high-pressure oil and gas systems904L: super austenite, designed for strong acid environments such as concentrated sulfuric acid and phosphoric acidFree material selection consultation can be provided, and models can be recommended based on your medium, temperature, pressure and other parameters.Q: What is the minimum order quantity (MOQ)? Are small batch orders accepted?A: Conventional specifications (DN15-DN300): MOQ 500 meters/batchSpecial materials/specifications (such as 904L, duplex steel): MOQ 200 meters/batchSupport sample orders (≥20 meters) to meet R&D or project testing needs.Q: Rust prevention treatment process for pipes? Is salt spray test supported?A: Standard delivery status: pickled and passivated (ASTM A380)Salt spray test: 304/316 series ≥72 hours (neutral salt spray), duplex steel ≥200 hoursOptional electrolytic polishing (EP) or titanium plating to improve corrosion resistance.Q: How long is the delivery time for regular orders? Is expedited delivery supported?A: Standard stock specifications: Delivery within 7 working days (covering mainstream models of DN15-DN600)Customized specifications: 15-25 days (depending on the complexity of the process)Expedited orders: Paying a 10% expedited fee can shorten the cycle by 30%, and the production schedule must be confirmed in advance.Q: How to deal with quality disputes? Is warranty provided?A: 12-month quality assurance period, provide material traceability batch numberIf specifications are not met or performance defects are found, respond within 72 hours, support return or compensation productionPerformance insurance agreement can be signed for major engineering projects.Q: Is processing supporting services provided?A: HYT supports:Laser cutting/groove processing (tolerance ±0.1mm)Bending/flaring (maximum bending angle 180°)Threading of pipe ends (in accordance with GB/T7306 standard)Customized packaging (wooden box shockproof/vacuum anti-rust film).Q: How to obtain samples and test reports?A: Free sample sections ≤3 meters (limited to conventional models)Prepaid freight means sending samples + complete test document packageSpecial material samples are charged cost (can be deducted from subsequent orders).
