Introduction to Titanium Tube:

The titanium tube used for tube replacement is lightweight, high in strength, and has higher mechanical energy. It is applied to heat exchange equipment, such as tubular heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, condensers, oil coolers, chillers, evaporators, and conveying pipelines. The nuclear power industry uses titanium tubes as the standard tubes for its units. Due to the corrosion caused by seawater, titanium tubes are commonly used as cooling devices for heat exchange tubes in large power plants. Some power plants should use titanium pipes for water with chloride ion content above 500. Copper pipes are used for chloride ion content below 500, and stainless steel pipes are used for chloride ion content below 200.

Titanium tube usage standard:

According to the different usage requirements and performance of titanium pipes, there are two domestic standards: GB/T3624-2010 GB/T3625-2007 ASTM 337 338

Titanium tube supply - number:

TA1, TA2, etc.

4. GB/T3620.1 Titanium and titanium alloys - designation and chemical composition

5. GB/T3620.2 Titanium and titanium alloy processing products - Chemical composition and allowable deviation of composition

Technical Requirements

1. The chemical composition of titanium and titanium alloy pipes should comply with the provisions of GB/T3620.1. When the purchaser re inspects, the allowable deviation of the chemical composition of Mingkun Titanium Industry should comply with the provisions of GB/T3620.2.

The allowable deviation of the outer diameter of the pipe should comply with the regulations in Table.

3. The allowable deviation of pipe wall thickness should not exceed ± 12.5% of its nominal wall thickness, and the allowable deviation of pipe wall thickness is not applicable to the welds of titanium welded pipes.

The length of the pipe should comply with the provisions in Table 2.

5. The fixed length or double length of the pipe should be within its indefinite length range. The allowable deviation of the fixed length is+10mm, and the double length should also be included in the cutting amount of the pipe. Each cutting amount should be 5mm.

Heat recovery device tube replacement

The waste heat recovery device, also known as the energy collector and recovery device, can be used for boiler waste heat recovery device, deaerator waste heat recovery, continuous discharge expansion tank waste heat recovery, continuous discharge expansion tank waste heat recovery, flue gas waste heat recovery, deaerator exhaust gas recovery, deaerator exhaust steam recovery, flue gas waste heat recovery, and other purposes.

Self regulating liquid level control device for gas-liquid two-phase flow

The self regulating liquid level control device for gas-liquid two-phase flow is based on the principle of gas-liquid two-phase flow. The two-phase flow drainage controller is suitable for liquid level control of various heat exchangers and expanders in enterprises such as power, chemical, petroleum, and metallurgy. It is a replacement of the drainage regulator.

tube replacement of tubular oil cooler

When purchasing a column type oil cooler for tube and core replacement, the cooling area should be informed. The cooling forms are divided into LY type light tube (for use) and LYC type fin type. Stainless steel tubes are generally selected for heat exchange and cooling, and purple copper, brass, and Titanium tubes can also be selected as heat exchange components according to user needs.

We undertake various types of tube coolers, condensers, oil coolers, chillers, air coolers, condensers, and other heat exchange and cooling tube replacement and renovation projects. Change the material of the pipes, such as copper pipes, stainless steel pipes, Titanium pipes, etc.

Replacing pipes for marine oil coolers

Welded steel pipes (also known as slotted pipes and welded pipes) are mainly used for auxiliary machinery in industries such as thermal power generation, chemical industry, and steel, such as condenser and heater pipe replacement, tubular marine oil cooler pipe replacement, oil-water cooler pipe replacement, tubular marine oil cooler pipe replacement, and Le tube cooler pipe replacement.

Steam seal heater tube replacement and renovation

The steam seal heater adopts a horizontal U-shaped surface heat exchanger for pipe replacement and transformation. The pipe material is stainless steel pipe, and in addition to expansion joint, the pipe also needs to be sealed and welded with the pipe plate; HSn-70-1 tin brass is also used and fixed on the tube plate by expanding the tube.

Condenser tube replacement

The condenser tube is replaced with stainless steel tube, and the copper tube is replaced with stainless steel tube. The 304/316l stainless steel tube heat exchange tube has high resistance to vibration, scaling, and corrosion. The condenser tube is replaced with stainless steel tube, and the welded steel pipe is mainly used in thermal power generation, chemical industry, steel, and other industries.

Sealing cooler tube replacement

The steam seal cooler generally adopts a horizontal U-shaped surface heat exchanger for pipe replacement, and the pipe material is stainless steel pipe. In addition to expansion joint, the pipe also needs to be sealed and welded with the pipe plate; HSn-70-1 tin brass is also used, which is fixed on the tube plate by expanding the tube bundle to the U-shaped tube end freely.

Positive displacement heat exchanger tube exchange

The U-shaped tube is used as a cooling tube for heat exchange tubes, and stainless steel U-shaped tubes are mainly used for various electrical instruments, condensers, heat exchange equipment, heat exchangers, low-pressure heaters, volumetric heat exchangers, boiler related auxiliary equipment, superheaters, heat exchangers, and refrigerators using welded austenitic stainless steel pipes.
