ステンレス鋼スクエアチューブ&パイプ

1. ステンレス鋼スクエアパイプとは何か?

ステンレス鋼スクエアパイプは、ステンレス鋼で作られた中空の四角断面チューブです. その独特の幾何学的形状と優れた性能により, 建築装飾, 家具製造, 機械構造, 産業工学に広く使用されています. 円形パイプと比較して, スクエアパイプは特定方向の曲げモーメントを受けた際、より高い断面二次モーメントと断面係数を提供し, 優れた曲げ抵抗性を示します. 主要パラメータには、材質グレード, 辺の長さ, 壁厚が含まれます, and length.

2. Classification of Stainless Steel Square Pipes

• By Application:
  • Decorative stainless steel square pipes
  • Structural stainless steel square pipes
  • Industrial stainless steel square pipes
• By Manufacturing Process:
  • Seamless Square Pipes: Produced through hot rolling, extrusion, or cold drawing processes, offering high integrity and pressure-bearing capacity.
  • Welded Square Pipes: Formed by shaping stainless steel coils or plates and then welding (typically TIG welding), featuring high production efficiency and relatively lower cost.
• By Material Grade:
  • 201 Stainless Steel Square Pipe
  • 304 Stainless Steel Square Pipe
  • 316L Stainless Steel Square Pipe Different materials correspond to varying levels of corrosion resistance and suitability for different environments.

3. Specifications of Stainless Steel Square Pipes

• マテリアルグレード: Common grades include 201, 304, and 316L austenitic stainless steels. 201 offers economic practicality, 304 provides excellent overall performance, and 316L boasts superior corrosion resistance.
• Side Lengths: 10×10, 15×15, 19×19, 20×20, 22×22, 25×25, 30×30, 38×38, 40×40, 50×50, 60×60, 80×80, 100×100 mm, 等.
• Wall Thickness: 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 mm, 等.
• 長さ: Standard length is typically 6 1本あたりのメートル数, with non-standard lengths available upon customer request.
• Surface Finish/Color: Common finishes include 8K mirror, ブラシ (snow sand, dry sand, oil sand, 等), and sandblasted. Through vacuum titanium plating, various decorative colors such as titanium gold, ローズゴールド, champagne gold, ブラックチタン, and zirconium gold are available to meet diverse aesthetic requirements.

4. How is a Stainless Steel Square Pipe Manufactured?

• Welded Square Pipe Production Process: Raw Material (Coil/Plate) → Uncoiling → Leveling → Forming (Roll Forming into Square) → TIG溶接 → 冷却 → 溶接ビード整形 → 長さ切断 → 直線化 → 表面処理 (ブラッシング, 研磨, 等) → 検査 → 梱包 → 出荷
• シームレス角形パイプ製造工程: 丸形ビレット → 加熱 → ピアシング → 熱間圧延 (または押出成形) 丸管に → 再加熱 → 寸法調整 (ダイスを通した押出または圧延) 角形に → 冷却 → 直線化 → 切断 → 表面処理 → 検査 → 梱包 → 入庫 (注意: シームレス角形パイプは比較的希少であり、多くの場合、丸パイプから加工されるか、または直接押出されます。)

5. ステンレス鋼角形パイプの主な特長

• 構造上の利点: The square cross-section provides better bending resistance compared to round pipes of the same weight, making it ideal for frames, supports, and applications requiring resistance to bending moments.
• Excellent Aesthetics: Sharp edges and clean lines offer a modern, sleek appearance, widely used in building facades, interior partitions, door and window frames, and furniture legs.
• Ease of Fabrication: Flat surfaces facilitate welding, connection, and installation, especially suitable for modular design and assembly.
• Material Properties: Inherits the benefits of stainless steel, including corrosion resistance, high-temperature resistance, anti-rust properties, long service life, and easy cleaning and maintenance.

6. Applications of Stainless Steel Square Pipes Stainless steel square pipes are a vital material in construction and industry, with extensive applications:

• 建築装飾: Curtain wall frameworks, door and window frames, staircase handrail posts, balcony railings, interior partitions, elevator trims, 等.
• Furniture Manufacturing: Table and chair frames, coffee table legs, bookshelves, display racks, storage shelves, 等.
• Industrial Use: Machinery frames, conveyor line supports, workbenches, 保護バリア, 化学パイプライン支柱, 等.
• 都市工学: 公共施設 (例：, バスシェルター, 自転車ラック), 景観設備, フェンス, 等.
