Warm-/kaltgewalztes Edelstahl-Rundrohr, Vierkantrohr

Product Description：

Seamless stainless‑steel round tubes are integrally formed by piercing and extruding solid steel billets with zero welding seams and compact uniform pipe‑wall structure. Featuring outstanding pressure‑resistance, corrosion‑resistance and high‑temperature endurance, common grades contain 304 & 316 stainless steel. They are widely applied in fluid transportation, machinery processing, equipment frames, chemical pipelines, new‑energy and construction‑hardware industries.

Key Features:

1. Seamless one‑piece forming craft  Hot‑rolled and cold‑drawn from steel billets with no weld seam. It resists cracking and leakage under high‑pressure working conditions and bears heavier load than welded steel pipes.
2. Superior anti‑corrosion property  The chromium‑nickel alloy creates a passive protective film against acid, alkali and moisture rust, suitable for damp and chemically‑corrosive working environments.
3. High‑precision pipe dimension  Cold‑drawn manufacturing strictly controls outer‑diameter and wall‑thickness tolerance. Smooth inner‑wall lowers fluid resistance and supports cutting, bending, turning and other deep processing.
4. Heat‑resistant and high‑strength performance  Stainless‑steel tubing maintains stable structure under high‑temperature conditions, ideal for furnace fittings, high‑temperature pipelines and machine structural parts.
5. Rich material & size options  Grade 304 suits regular indoor‑outdoor use; grade 316 delivers seawater‑proof heavy‑duty corrosion resistance for marine and chemical projects. Custom outer diameter, wall thickness and fixed‑length cutting are available.

Application Scenarios:

Pipeline Transport, Boiler Pipe, Hydraulic/Automobile Pipe, Oil/Gas Drilling, Food/Beverage/Dairy Products, Machinery Industry, Chemical Industry, Mining, Construction & Decoration, Special Purpose.
