Filling Equipment Stainless Steel Tube

Shuangsen’s filling equipment stainless steel tube portfolio is engineered for reliability in critical fluid handling. From filling machinery support structures to cooling systems for AI data centers (Huawei, Envicool), our tubes exhibit exceptional corrosion resistance and mechanical strength. We employ diamond‑mold forming, nitrogen‑shielded welding, and online roundness control — ensuring true roundness and consistent weld seam integrity. Material grades 304, 316, and 316L are available with surface finishes from 180# to mirror (800#). Each lot is verified with tensile, elongation, and roughness checks. With 133 automated production lines, we maintain short lead times (3–45 days) and offer free samples for qualification. Our factory in Wenling, near Ningbo and Shanghai ports, enables efficient global logistics. For projects demanding high‑purity or high‑pressure fluid transport, Shuangsen provides traceable, certified tube systems that perform beyond expectations.

Material grades & mechanical properties

All tubes are manufactured from premium stainless steel coils. The table below lists standard grades, chemical composition, and tensile/elongation values — essential for selecting the right material for your filling equipment environment.

Key advantage: Low OD tolerance enables secure grip‑ring connections. Complete in‑house testing ensures zero leakage and extended service life — essential for any filling equipment stainless steel tube system.

Manufacturing & surface finishing

• Diamond mold forming – round tubes are true round, straight without deformation.
• Full argon & nitrogen gas protection welding – full weld path, high strength, pressure resistance >700 kg.
• Surface mechanical polishing – 180# to 400# standard, mirror finish 400#‑800# available.
• Salt spray test – 1000 hours without surface corrosion (verified per ASTM B117).
• Roughness detection – every batch tested for surface integrity, critical for sanitary filling lines.
