Pipe cutting and groove processing of titanium pipes!

As the application fields of titanium tubes continue to expand, so does the amount used. Our titanium pipes have been applied in construction, in order to make the construction more scientific to provide users with high-performance titanium pipes.

The research on refractory materials for casting molds has always been linked to the crucible materials for smelting titanium tubes and titanium alloy tubes. Based on dynamics, the crucible material has to be in contact with the titanium liquid for a long time during smelting, and the titanium liquid is in contact with the titanium liquid for a long time. The contact time of the holding material is much shorter, so the usable crucible material can be used as the casting material of the Grade 9 Ti3Al2.5V Titanium Tube

The materials that have been studied include carbides, nitrides, borides, sulfides, oxides, rare earth oxides, fluorides, oxyfluorides, sulfur oxides, and refractory metals such as W and Mo. Only a few materials have high chemical stability to titanium liquid, including ThO2, some rare earth oxides, TaB2, Npc, some rare earth sulfides and some rare earth oxyfluorides.

Pipe cutting and bevel processing of titanium pipes; pipe cutting and bevel processing should be carried out by mechanical processing methods in a special workplace. Use clean water with non-polluting media for cooling during processing to prevent oxidation. Processing tools should be dedicated and kept clean to prevent iron pollution. The processed nozzle should ensure that the surface is smooth and free of defects such as cracks and heavy leather. The maximum inclination of the incision plane does not exceed 1% of the pipe diameter.

Surface cleaning: Use a steel wire brush made of austenitic stainless steel to remove scale, paint, dirt, dust, and debris that can react with titanium welded tube on all welding surfaces of the titanium pipe and within 100mm near the groove. Use a grinding wheel to trim the machined surface to remove flashes, burrs, convexities and other defects.

Align and clamp the titanium pipe and fittings. The axis should not be offset, the gap should be uniform, and the titanium pipe should be prevented from being damaged and contaminated during assembly. Avoid forced pairing. Tack welding adopts the same welding process as formal welding.

Titanium tube degreasing treatment: Use celluloid sponge dipped in sulfur-free ethanol or sulfur-free acetone to degrease all the welding surfaces and the vicinity of the groove within 50mm, and there should be no residue on the surface after treatment. Welding: It should be carried out under the conditions specified in the relevant standards.
