Products Description
Stainless Steel 316 Introduction
316 is chrome-nickel austenitic alloy. It also contains molybdenum which increases general corrosion resistance,improves
resistance to pitting from chloride ion solutions, and provides increased strength at high temperatures.316 also provide excellent fabricability and formability. It is also called Marine Grade Stainless Steel.

Stainless Steel 316 Round Pipe Introduction
Stainless Steel 316 Round Pipe is a widely used seamless and welded tubular product for fluid transmission and structural support in harsh corrosive environments. Containing molybdenum element, grade 316 stainless steel delivers superior resistance to chloride corrosion, pitting corrosion and crevice corrosion compared with 304 stainless steel, and maintains stable mechanical performance under high temperature and humid conditions.
Manufactured in compliance with ASTM, DIN and ISO standards, this round pipe features excellent ductility, weldability and oxidation resistance. It is available in various outer diameters, wall thicknesses and surface finishes including pickled, bright annealed and polished options. The smooth inner surface reduces fluid resistance and avoids medium contamination during service.

Stainless Steel 316 Round Pipe Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality 316 stainless steel tube blanks that comply with ASTM and international industrial standards. Strictly inspect alloy composition, surface condition, internal compactness and mechanical properties to exclude raw materials with cracks, inclusions and oxide defects. Precisely cut qualified tube blanks into fixed-length sizes according to pipe diameter and wall thickness specifications, providing stable and consistent raw materials for subsequent piercing and forming.
2.Surface Pretreatment & Hot Piercing:
2.Surface Pretreatment & Hot Piercing:
Complete standardized degreasing, cleaning and oxide removal pretreatment to ensure clean and smooth blank surface. Adopt professional high-temperature hot piercing process to perforate solid tube blanks into preliminary tubular bodies. Strictly control heating temperature and piercing speed to ensure uniform wall thickness, regular pipe outline and dense internal metal structure without structural defects.
3.Cold Rolling, Sizing & Shaping:
3.Cold Rolling, Sizing & Shaping:
Perform multi-pass precision cold rolling and sizing treatment on pierced pipe blanks to optimize outer diameter, inner diameter and wall thickness accuracy. Conduct overall straightness correction and roundness calibration to eliminate rolling deformation and surface irregularities. The finished pipe body features smooth inner and outer walls and accurate dimensional tolerance, meeting high-standard pipeline assembly requirements.
4.Solution Heat Treatment & Stress Stabilization:
4.Solution Heat Treatment & Stress Stabilization:
Carry out professional solution annealing heat treatment for formed 316 stainless steel pipes. Fully eliminate residual internal stress generated during hot piercing and cold rolling, refine internal grain structure and stabilize mechanical performance. This process greatly enhances intergranular corrosion resistance and structural stability, adapting the pipes to high-pressure and corrosive working conditions.
5.Pickling Passivation & Full Quality Inspection:
5.Pickling Passivation & Full Quality Inspection:
Conduct pickling, cleaning and passivation treatment to remove surface oxide scale and form a dense protective film, improving overall anti-corrosion performance. Implement comprehensive full-range inspection including dimensional tolerance detection, surface defect screening, hydraulic pressure test, nondestructive flaw detection and mechanical property sampling test to ensure full compliance with industrial pipeline standards.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Mark all qualified stainless steel 316 round pipes with material grade, specifications, execution standard and batch information. Adopt dust-proof, moisture-proof, anti-collision and scratch-resistant professional packaging to protect pipe ends and pipe surfaces. Finished products are classified and stored in standardized warehouses, and delivered after strict final inspection.
