Technical Specifications & Parameters of Seamless Steel Pipe For Sale

Manufacturing Process Flow – Seamless Steel Pipe For Sale

The precision-built seamless steel pipe for sale is manufactured through an intricate process that ensures integrity, consistency, and durability.
Key Steps:

• Piercing: Solid cylindrical billet is heated to 1200–1300°C and pierced under high pressure to form a hollow shell.
• Elongation: The pierced shell is rolled through mandrel mills for wall thickness reduction and diameter sizing.
• CNC Machining: For sizing, beveling, and tolerance control at ±0.5 mm, critical for oil & gas specifications.
• Heat Treatment: Annealing, normalizing, or quenching/tempering for strength, toughness, and grain refinement.
• Surface Finishing: Pickling, passivating, or coating (FBE, 3PE) per NACE / ISO requirements.
• Non-Destructive Testing (NDT): 100% Ultrasonic, Eddy Current, or Hydrostatic testing as per ISO 9001/API 5L/ASTM protocols.
• Marking & Packaging: Automated inkjet and bundling under ISO14001 eco-friendly standards.

Each stage is designed for maximum lifecycle, crack resistance, and surface quality, essential for high-pressure and corrosive applications.

Seamless Steel Pipe For Sale – FAQ & Professional Terminology

Q1: What is the difference between seamless and welded steel pipe?

Seamless pipe is made from a solid billet that is pierced and rolled into a hollow tube, eliminating weld seams and potential weak points. Welded pipe is formed by bending and welding a steel strip; it is more economical but typically offers lower mechanical performance and pressure resistance.

Q2: What does “17 4 seamless tubing for sale” refer to?

“17-4” refers to stainless steel grade 17-4PH (Precipitation Hardened: 17% chromium, 4% nickel). It delivers high strength and corrosion resistance, ideal for aerospace, petrochemicals, and high-pressure instrumentation.

Q3: What industry standards apply to seamless pipes?

Common standards: API 5L/5CT (oil & gas), ASTM A106/A53 (boiler/process), ISO 9329, DIN 17175, EN 10216, and NACE MR0175 (corrosion for sour service).

Q4: What technical terms are critical when specifying seamless pipes?

OD (Outer Diameter): Pipe’s outside width, affects flow/capacity.
Wall Thickness (WT): Determines pressure rating.
Yield/Tensile Strength: Measure of load durability and plastic deformation; higher values indicate stronger piping.
Corrosion Allowance: Extra wall thickness or coatings to OEM/project specifications to ensure longer service life.

Q5: How is quality tested for seamless steel pipe for sale?

Each pipe undergoes non-destructive testing (ultrasonic, eddy current, hydrostatic) and mechanical evaluation (hardness, tensile, impact) in compliance with ISO 9001, API, and, for special uses, FDA and EN standards.

Q6: What is the typical delivery period and warranty?

Stock items: 7–14 days. Project custom: 3–5 weeks depending on size/spec. Industry-standard warranty is 12–36 months; SZPipeFitting offers detailed MTC and extended proactive support.

Q7: Can seamless steel pipe be customized for unique flow media or installation?

Yes. Pipes can be specified for metallurgy (Duplex, 17-4PH etc.), wall thickness, length per ISO standards, and anti-corrosion coatings. Custom beveling and threading available for power, oil, or chemical installations.
