Product Specifications

Production and Processing Details

Item	Key Data
Forming Methods	Hot Forming: Applicable to thick-walled materials/high-strength alloys, stress relief annealing required after forming Cold Forming: Suitable for thin materials/316L stainless steel, no thermal deformation
Surface Treatment	Sand Blasting: Ra 1.6μm - 3.2μm (enhances coating adhesion) Pickling: Forms a passive film (improves corrosion resistance, meets hygiene standards) Oil Coating: Food-grade anti-rust oil optional Descaling: Mechanical/chemical descaling (ensures clean surface before welding) Customization: Such as mirror polishing for high-cleanliness fields
Inspection Standards	Ultrasonic Testing (UT): 100% coverage of key parts to detect internal cracks and inclusions Radiographic Testing (RT): Complies with ASME BPVC Sec.V Level II standards Magnetic Particle Testing (MT): For ferrous materials, detects surface/near-surface defects Penetrant Testing (PT): For non-ferrous materials, ensures no surface leakage Time of Flight Diffraction (TOFD): Accuracy ±0.1mm, detects internal defects
