Key Specifications

Why Are Annealing & Pickling the Heart of Durability?

For seamless steel pipes, annealing and pickling are critical processes that can influence their corrosion resistance. The annealing process eliminates internal stresses generated during cold rolling and restores the material's crystalline structure. The subsequent pickling step thoroughly removes surface scale, forming a dense passivation layer. This passivation layer serves as the first line of defense against stainless steel corrosion. Only through thorough solution annealing and uniform pickling can pipes withstand prolonged use in harsh environments. MTSCO's core facility, HUXIN PIPE, operates advanced annealing furnaces. We strictly control temperatures and holding times to ensure every delivered A&P pipe features a clean surface and stable performance.

How Do We Guarantee Every Pipe’s Quality?

To ensure the safety and reliability of industrial piping, we implement rigorous quality inspection procedures. For DN80 seamless pipes, we focus not only on dimensional accuracy but also prioritize internal quality and material purity. Our core inspection methods include:

• Raw Material Re-inspection: We source only round bars from major manufacturers and conduct PMI test before warehousing to verify chemical composition compliance.

• Non-Destructive Testing: 100% eddy current testing (ET) or hydrostat testing is performed to eliminate potential cracks or leaks.

• Mechanical Property Testing: Regular sampling for tensile, flaring, and flattening tests verifies physical performance.

Backed by ISO/PED certification systems, MTSCO commits to 100% inspection of every shipment before dispatch, ensuring worry-free procurement.

Where Can These Pipes perform?

Annealed & Pickled seamless pipes are widely used in industrial fluid transmission. While this surface treatment isn't as glossy as polished pipes, it offers exceptional cost-effectiveness and outstanding corrosion resistance. They are commonly employed in process pipelines for petrochemical, papermaking, wastewater treatment, and power generation industries. When conveying acidic or alkaline liquids, gases, or high-pressure steam, these pipes represent the most standard and reliable choice for engineering projects.

 FAQ

Q1: What is the main difference between Annealed & Pickled and Polished finish?

A1: “Annealed & Pickled” (A&P) is a matte, industrial finish focused on corrosion resistance and cost-effectiveness. Polished finish is shiny, mainly for decoration or sanitary use. For industrial fluid transport like DN80 pipes, A&P is the standard choice.

Q2: What other seamless pipe specifications do you offer?

A2: We supply a comprehensive range of specifications, with outer diameters (OD) from 8mm to 711mm and wall thicknesses (WT) from 1mm to 50mm. Through close collaboration with our holding factory HUXIN PIPE, MTSCO can also provide extra-long pipes up to 18 meters and 25 meters to meet your special project requirements.

Q3: Do you accept small batch or customized orders?

A3: Absolutely. Through our exclusive partnership with our holding factory, MTSCO can swiftly respond to your customization needs. Whether it involves non-standard dimensions, special chemical compositions, or specific mechanical property requirements, we can efficiently fulfill your requests.
