In addition, we have a 6-meter-long coiling machine capable of producing 6-meter-long welded pipes with only one longitudinal weld, and we hope that we can provide high-quality titanium products for more customers.

The following is a brief introduction to titanium fittings.
1. There are many types of pipe fittings, which are divided into the following categories according to their use:
(1) Pipe fittings used for pipe joints are: flanges, unions, pipe clamps, clamps, ferrules, hose clamps, etc.
Cold drawn welding tee
Cold drawn welding tee
(2) Pipe fittings that change the direction of the pipe: elbows, elbows
(3) Pipe fittings that change the pipe diameter: variable diameter (reducing pipe), reducer elbow, branch pipe, and reinforcing pipe
(4) Increase the pipe fittings of the pipeline: three links, four links
(5) Pipe fittings for pipeline sealing: gasket, raw material belt, wire hemp, flange blind plate, pipe plug, blind plate, head, welding plug
(6) Pipe fittings for pipe fixing: snap rings, tow hooks, rings, brackets, brackets, pipe clamps, etc.

2. The principle of using titanium pipe fittings
The flange is a joint between the pipe and the pipe for the connection between the pipe ends; it is also used for the flange on the inlet and outlet of the equipment for the connection between the two devices, such as the flange of the reducer. A flange connection or a flange joint refers to a detachable connection in which a flange, a gasket and a bolt are connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in the pipeline installation. It is used on the equipment to refer to the inlet and outlet flanges of the equipment. There are holes in the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange threaded connection (threaded connection) flange, welded flange and clip flange. Flanges are used in pairs. Low-pressure pipes can be used with wire-bonded flanges, and welded flanges are used for pressures above four kilograms. A gasket is placed between the two flanges and then bolted. Different flange thicknesses for different pressures use different bolts. Pumps and valves, when connected to the pipeline, the parts of these equipment are also made into the corresponding flange shape, also known as flange connection. Connection parts that are bolted at the same time around two planes are generally referred to as “flanges”. For example, the connection of ventilation ducts may be referred to as “flange parts”. However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the pump “flange parts”. Smaller ones such as valves can be called “flange parts”.

3. Characteristics of titanium alloy
Titanium (Ti) has high strength, light weight, high heat resistance and low temperature toughness, and good processing properties and weldability. For the production of valves, it is mainly casting pure titanium and forging pure titanium ZTA2.
Titanium exhibits corrosion resistance, corrosion resistance, and even fire and explosion due to different working conditions such as temperature. Therefore, the ordering and design selection should be clearly defined for the nature of the medium used (concentration, temperature, etc.).
Titanium valves have excellent corrosion resistance in a variety of oxidatively aggressive media and neutral media.
Titanium has excellent corrosion resistance in nitric acid below the boiling point and concentration ≤ 80%. In the case of fuming nitric acid, when the NO2 content exceeds 2% and the water content is insufficient, titanium reacts with fuming nitric acid to explode. Therefore, titanium is generally not used for high-temperature nitric acid having a content of 80% or more.
Titanium is not resistant to corrosion in sulfuric acid, and titanium has moderate corrosion resistance in hydrochloric acid. It is generally believed that industrial pure titanium can be used in hydrochloric acid at a concentration of 7.5% at room temperature, 3% at 60 ° C, and 0.5% at 100 ° C. Titanium can also be used at a concentration of 30% at 35 ° C and a concentration of 10% at 100 ° C and 100 ° C. At a concentration of 3% phosphoric acid at °C.
Titanium is not resistant to corrosion in HF (fluoric acid), titanium is not resistant to corrosion in acidic fluoride solutions, titanium is resistant to corrosion in boric acid and chromic acid, and can be used in hydroiodic acid and hydrobromic acid.
Titanium can be used in 60 ° C 10% sulfuric acid and 90% nitric acid mixed acid, boiling 1% hydrochloric acid and 5% nitric acid mixed acid and room temperature aqua regia (Note: aqua regia is a mixture of 3 volumes of concentrated hydrochloric acid and 1 volume of concentrated nitric acid) in.
Titanium is completely resistant to corrosion at various concentrations of barium hydroxide, calcium hydroxide, magnesium hydroxide, sodium hydroxide and potassium hydroxide at room temperature, but cannot be used in boiling sodium hydroxide and potassium hydroxide. The ammonia in the base exacerbates the corrosion of titanium.
Titanium has a high operating temperature of 300 ° C in tap water, river water and air. Titanium can be used in seawater with a high flow rate of 20m/s. Titanium has high corrosion resistance in seawater at temperatures ≤120°C. If the temperature is higher than 120°C, pitting corrosion and crevice corrosion may occur.
In addition to formic acid, oxalic acid and concentrated citric acid (concentration ≥ 50%), titanium has excellent corrosion resistance to all organic acids, but titanium is easy when the water content in organic acids is too low (<0.1%). Pitting corrosion occurs.
Titanium has excellent corrosion resistance in hydrocarbons and chlorinated hydrocarbons. Titanium can react violently in dry gas to form TiCl4, and there is a risk of fire, but titanium has good corrosion resistance in wet chlorine (water content of 0.3 to 1.5%).
Titanium is stable in HCl dried at 20-160 ° C, but hydrochloric acid causes corrosion to titanium in wet hydrogen chloride.
The pitting potential of titanium in chloride solution is higher than that of stainless steel. The pitting corrosion resistance of titanium against chloride ion is better than that of stainless steel, so titanium has been widely used in chloride solution.
Titanium generally does not produce pitting at temperatures ≤ 80 ° C, but at high concentrations of medium concentration chloride solution (eg 25% aluminum chloride solution at 100 ° C, 70% calcium chloride solution at 175 ° C, 25% at 200 ° C) Pitting corrosion is more likely to occur in magnesium chloride solution and 75% zinc chloride solution at 200 °C.
