Description
Product Name: Welded Pipe Cap (Stainless Steel Pipe Cap, Material: 2205 Duplex Steel)
Product Description: This is a butt-welded pipe cap (C) complying with GB/T12459-2017 standard, with a size of DN76 (3"), made of 2205 duplex stainless steel (UNS S32205/S31803).
Raw Materials: Made of 2205 duplex stainless steel plates or forgings, it combines the advantages of austenite and ferrite, featuring high strength and excellent corrosion resistance.
Production Process: Blanking → Cold stamping / Spinning forming → Solution heat treatment → Machining of bevel edges → Pickling and passivation → Non-destructive testing → Dimensional inspection → Packaging.
Application Fields: Widely used for pipeline end sealing in harsh corrosive environments, such as petrochemical industry, offshore platforms, papermaking, desulfurization and environmental protection industries.
Temperature and Pressure Resistance: It has excellent resistance to stress corrosion cracking, a wide applicable temperature range (approximately -50°C to 300°C) and outstanding pressure resistance performance, with specific parameters calculated based on wall thickness.
Advantages of Hebei Hexin Pipe Fittings: 1. Capable of processing and heat treating special stainless steels including duplex steel; 2. Complete surface pickling and passivation treatment to ensure corrosion resistance; 3. Strictly qualified product chemical composition and mechanical properties.
Production Size Range: Capable of manufacturing pipe caps, elbows, tees and other pipe fittings in various stainless steel materials (304, 316L, 321, 2205, etc.), with sizes ranging from DN15 to above DN1000.
