Titanium parts processing

1. Provide drawings: size specifications, material requirements, precision requirements, the number of processing, processing time.

2. Sample processing: reference size, reference material, design drawings, precision requirements, the number of processing, processing time.

图纸加工2.jpg1. Flat welding: Only welding the outer layer, without welding the inner layer; commonly used in medium and low pressure pipe, the nominal pipe pressure to be less than 2.5MPa. Flat welding flange sealing surface there are three, namely, smooth, convex and mortise groove, which is the most widely used smooth, and affordable, cost-effective.

2. Butt welding: the inner and outer flanges must be welded, generally used for medium and high pressure pipe, pipe nominal pressure between 0.25 ~ 2.5MPa. Butt flange connection surface sealing surface is convex, the installation is more complicated, so labor costs, installation methods and auxiliary materials costs are relatively high.

3. Socket welding: Generally used for nominal pressure less than or equal to 10.0MPa, nominal diameter less than or equal to 40mm in the pipeline. 4. Loose sets: Generally used for pressure is not high, but the medium is more corrosive pipe, so the corrosion resistance of such flanges strong, mostly made of stainless steel. This connection is mainly used for the connection of cast iron pipes, rubber lined pipes, non-ferrous metal pipes and flange valves, etc., and the connection of process equipment and flanges are also flanged
