Precautions for installation and transportation of titanium tubes, titanium and titanium alloy tubes.


Installation of titanium pipe

Condensation discharge, emission, instrumentation taking source parts, and other small holes are common in titanium pipe construction and are challenging to open using standard techniques. The size of the hole as well as the precise location of the hole are drawn on the titanium tube in question prior to welding. Drill numerous small holes along the centerline of the hole's edge with a lathe; the denser the holes, the better. Use a copper hammer to lightly hit the center of the hole arc plate to detach it after all the holes have been drilled. Then, using a special tool like a fine tooth round file, process the holes to meet the requirements.

Quality inspection of titanium pipe

In the construction of titanium pipe and titanium alloy pipe, the conventional operations are as follows:

one, titanium alloy pipe elbow, should be made regular inspection, often reflect the processing surface must adhere to clean, remove dirt, stored in the indoor drab local, inhibit the pile or open storage.

two, titanium alloy pipe elbow ball valve, stop valve, gate valve use, only fully open or fully closed, do not allow to adjust the flow, inhibit the sealing surface erosion, accelerate wear.

Three, the gate valve and the upper thread stop valve have reverse sealing equipment, the hand wheel to the top surface of the head will never rust, will not be corrupted. Often adhere to titanium alloy pipe titanium elbow monotonous and ventilation, adhere to the clean and cut, in accordance with the accurate storage footsteps.



Transportation of titanium pipe

Titanium and titanium alloy pipe installation Titanium and titanium alloy pipe transportation and storage titanium pipe manufacturers should pay attention to not contact with iron materials, collision.

1, titanium and titanium alloy tube cutting should be mechanical method, cutting speed should be appropriate at low speed; Special grinding wheel should be used when titanium pipe is cut or trimmed by grinding wheel; Flame cutting shall not be used. Groove should be processed by mechanical method.

2, titanium alloy welding pipe welding should be used inert gas shielded welding or vacuum welding, can not use oxygen - acetylene welding or carbon dioxide gas shielded welding, also can not use ordinary manual arc welding.

3. Titanium and titanium alloy tubes shall not be knocked and squeezed with iron tools and materials when they are installed; Rubber plate or soft plastic plate should be inserted between the carbon steel support and hanger and the titanium and titanium alloy pipe, so that it does not directly contact with the titanium and titanium alloy pipe; When the titanium and titanium alloy pipes pass through the wall and floor, they should be equipped with sleeves with a clearance of no less than 10mm and be filled with insulation, which should not contain iron impurities.

4. Titanium and titanium alloy pipes should not be directly welded with other metal pipes. When connection is required, a looper flange connection can be used. The non-metallic gaskets used are generally rubber pads or plastic pads, and the chloride ion content should be controlled not to exceed 25ppm.

Welding of titanium pipe

Receive alkali washing, water-soluble detergent, chlorine solvent sandblasting, shot blasting and other methods to clean titanium standard parts according to workpiece requirements and surface conditions.

1, the use of the electrode should be connected to the monotonous, titanium calcium type should be 150℃ monotonous 1 hour, low hydrogen type should be 200-250℃ monotonous 1 hour (can not be repeated drying, or the drug skin simple cracking off), guard the electrode drug skin sticky oil and other dirt, to avoid increasing the carbon content of the weld and affect the quality of the welding parts.

2, elbow welding, by repeated heating out carbide, depression resistance to degradation and mechanical function. After welding, the hardening is large and the crack is easily bred.

3, if the receiving of the same model of electrode welding, it is necessary to hold more than 300℃ preheating and after welding about 700℃ slow cooling treatment. Inni alloy pipe welding rods should be used if the welds cannot be subjected to post-weld heat treatment. Accurate cleaning titanium alloy pipe elbow, can improve its use of quiet function, extend its service cycle.

4, titanium pipe elbow in the equipment to maintain the tightness, inhibit the appearance of leakage, affect the normal work of the pipeline.

5. When titanium alloy pipeline elbow is equipped, the titanium alloy pipeline elbow can be directly equipped on the pipeline according to the connection step, and the equipment can be held according to the direction of use. In ordinary environment, it can be equipped on the bearing of the pipeline, but it needs to be easy to operate the inspection, and the medium flow of titanium alloy pipe elbow should be prevented from upstream below the longitudinal valve disc, and titanium alloy pipe elbow can only be equipped horizontally.
