201 304 316 Stainless Steel Pipe Fittings Grooved Threaded Welded 90 Degree Elbow Fittings

Cost-effective austenitic stainless steel, good structural strength and oxidation resistance. Fine indoor and dry environment anti-rust performance, ideal for general decoration, civil water pipes and ordinary non-corrosive pipeline systems.

Classic 18-8 austenitic stainless steel, excellent overall mechanical property, weldability and atmospheric corrosion resistance. Resists fresh water, steam and weak oxidation medium, suitable for most commercial, building, fire protection and conventional industrial pipelines.

Molybdenum alloy added grade, greatly improved resistance to chloride, salt spray, seawater and weak acid & alkali corrosion. Superior anti-corrosion and high temperature stability, perfect for coastal areas, chemical, marine, pharmaceutical and harsh corrosive working conditions.

• Grooved Type: Fast clamp connection, no welding, easy installation and disassembly, convenient for later maintenance, widely used in fire protection and large water pipeline.
• Threaded Type: Internal / external thread precision tapping, tight match, good sealing effect, suitable for small-bore pipeline and equipment interface connection.
• Welded Type: Butt weld / seamless welded structure, smooth transition, high pressure bearing, no leakage, suitable for high-pressure industrial and long-distance pipeline engineering.
