Welded Tube Fitting

**Welded Pipe Fittings** Applicable Medium: Oil, water, gas and other non-corrosive or corrosive media. For welded sealed pipe fittings, the specifications for the matching steel pipes are relatively flexible. After welding to the pipeline, they have characteristics such as firm connection and good sealing performance, which is why they are widely used in systems such as refining, chemical industry, light industry, textiles, national defense, metallurgy, aviation, and shipping. They are also suitable for hydraulic transmission pipelines in various mechanical engineering and machine tool equipment. When the production of **Sleeve Type Pipe Fittings** cannot meet the needs or in cases with strong corrosion, they can be prioritized. **Manufacturing Standards for Welded Pipe Fittings** 1. Metal pipe fittings for fluid transmission and general use with O-ring flat sealing joint (JB/T 966-2005) 2. Conical Seal **Welded Straight Pipe Fittings** (JB/T 6381.1-2007) 3. Conical Seal Welded Straight 55° Non-Sealing Pipe Thread Pipe Fittings (JB/T 6381.2-2007) 4. Conical Seal Welded Straight 55° Sealing Pipe Thread Pipe Fittings (JB/T 6381.3-2007) 5. Conical Seal Welded Straight 60° Sealing Pipe Thread Pipe Fittings (JB/T 6381.4-2007) 6. Conical Seal Welded 90° Elbow Pipe Fittings (JB/T 6382.1-2007)
