Matte titanium tubing is made from zigzag molding and welding from titanium sheets or strips. It is categorized in various ways. According to the welding seam, it can be divided into straight seam matte titanium pipe and spiral matte titanium pipe; while according to the use, it is divided into usual matte titanium pipe, galvanized matte titanium pipe, oxygen blowing matte titanium pipe, wire casing, metric matte titanium pipe, roller pipe, deep well pump pipe, automotive pipe, transformer pipe, electro-welded thin-walled pipe, electro-welded profiled pipe, and spiral matte titanium pipe, etc. Various kinds of matte titanium pipe can be classified.
Usually, matte titanium pipe is mainly used to transport low-pressure fluids, such as water, gas, air, oil, and heating steam. This kind of titanium tube is usually made of Q195A, Q215A, Q235A titanium, or other soft titanium that is easy to weld. Titanium tube to water pressure, bending, flattening, and other experiments, the quality of the appearance of certain requirements, usually delivery length of 4-10m, and often need to be fixed-foot (or times the size) delivery. Matte titanium tube standard is expressed in nominal caliber (mm or inches), nominal caliber is different from the actual size, titanium tube is according to the wall thickness of the usual titanium tube and thickened titanium plate two kinds of, according to the way the tube end is divided into two kinds of with threads and without threads.
Next, we briefly analyze the specific applications of several kinds of matte titanium tubes:
1. usually matte titanium tubing is mainly used to transport usually lower pressure fluids, such as water, gas, air and oil.
2. usually titanium carbon wire casing is used in industrial and civil buildings, installations of machinery and equipment, such as electrical installations in the project to protect the wires.
3. straight seam electric matte titanium pipe is usually divided into metric electric matte titanium pipe, electric welding thin-walled pipe, transformer cooling oil pipe, etc., the weld seam is parallel to the longitudinal direction of the titanium pipe.
4. spiral seam submerged arc matte titanium pipe for pressurized fluid transportation is mainly used for the transportation of oil, natural gas, and other high-pressure fluids, with strong pressure-bearing capacity, good welding performance, safety, and reliability.
5. Spiral seam high-frequency matte titanium pipe for pressurized fluid transportation is also used for laying pipelines for transporting oil, natural gas, etc., which has the advantages of large caliber and high transportation efficiency.
6. Usually low-pressure fluid transportation spiral seam submerged arc welded titanium pipe is mainly used for water, gas, air steam, and other low-pressure fluid transportation.
In addition, the hardness of matte titanium pipe can be determined by three hardness test methods, namely, cloth, Luo, and Vi, which results in HB, HRB (or HRC), and HV hardness values. The portable appearance Rockwell hardness tester and pipe Rockwell hardness tester developed by our company can quickly and accurately test the hardness of matte titanium pipe, which solves the problem that was difficult to solve in the past in China.
