Various kinds of oil, gas, water, chemical industry and new built pipeline
The cleaning pig produced by Shenyang Wensheng is mainly used in petroleum, chemical industry, electrical power and metallurgy for cleaning pipeline and so on. It has the characteristics of such as simple structure, convenient operating.
Application area:
Before operating inner inspecting of petroleum pipeline, pig and intermittently operate oil pipeline. Clear the freezing point oil, paraffin precipitation and scale to reduce back-pressure of oil and friction, as well as oil temperature.
Characteristics of cleaning pig:
1 Simple structure, convenient operating and suitable for daily maintenance;
2 Use the quick opening closure which is easy to quickly open or close the receivers & launchers;
3 There is insurance device which is safe and reliable;
4 The way-ball indicator can be installed to indicate the process of receiving and launching the ball.
The quick opening closure is used for the pressure pipe or on the circular opening of pressure container. It is also a kind of device to achieve quickly opening or closing. The quick opening closure generally consists of flange, head cover, hook ring or clamp, sealing ring, security interlocking mechanism, opening and closing mechanism, rotary arm, short segment, and so on.
Application industries:
Petroleum, natural gas
Types of fast opening closure:
Tooth clutch type, clamp type, locking ring type, cut-in type
How to open the quick opening closure:
1 Inspect the pressure inner of the cavity of the closure cylinder, and do not operate until the pressure number return to zero.
2 Inspect that whether the valves of inlet and outlet are closed without any pressure.
3 Slowly release the pressure alarm bolt, and inspect whether there is pressure in the container.
4 Take the pressure alarm bolt and its lock plate off the closure if there is no pressure.
5 Rotate the handle 180 degree anticlockwise to start the drive chain and horseshoe mechanism device, simultaneously the locking belt progressively shrank back to the gate recess.
The three-petal clamp quick opening closure has function of safe self-locking. This function prevents the closure loosing while tightening, also avoids opening the closure under pressure. This kind of equipment is widely used in the fields of natural gas, chemical industry, metallurgy and medicine.
Structure features:
1 There is no relative motion between sealing surface of closure and sealing ring. It is not easy to damage the sealing ring, which can make the whole system achieve better sealing effect;
2 Three-petal clamp takes motion while tightening and reduces the length of open screw;
3 The bearing capacity area of teeth is simultaneously enlarged (interlocking area is more than 90%). It is more suitable for the gas pipeline with high pressure and large caliber. The main pressure-bearing part has no welding connector;
4 There is safe self-locking function.
Application field:
Natural gas, chemical industry, metallurgy and medicine
Operating instructions:
1 Inspect whether each instrument on the machine indicates normally;
2 There should not be leakage among the container and quick opening closure, as well as each connection part;
3 Necessary explosion tools, fire extinguisher, firefighting felt and other equipments should be enough;
4 The quick opening closure should be operated by one person under the guard of other person;
5 No person is allowed to stand in the front of the quick opening closure while opening or closing.
The steel brush cleaning pig, produced by Shenyang Wensheng Instrument Equipment Co.,Ltd, is used for rust cleaning and paraffin removal inner of surface of pipeline. It has the characteristics of strong passing ability, perfect stiffness and obvious work effect. The support-type steel brush cleaning pig has more obvious work effect.
Characteristics of steel brush cleaning pig:
1 Clean the corrosive substances in the pipeline; reduce the abrasion of inside wall of pipeline caused by the corrosive substances; define the direction of pipeline again; inspect that whether the pipeline is out of shape; reduce work back-pressure;
2 Clean the freezing point oil, paraffin precipitation and scaling inside of the pipeline to realize decrease back pressure of oil and abrasion, as well as reduce the temperature of oil;
3 Clear up the pipeline which has polymerizable material; separate different pipeline transportation medium;
4 Clean up the sundries, free rust, drainage and exhaust in pipe;
5 Inspect quality of project; exhaust before test of water pressure;
6 Clean the water scale and sediment
Function of steel brush cleaning pig:
The cleaning pig is used for pigging and hose sweeping before production, which can clean up the stones, lags and other sundries remaining in the pipeline while construction. Using the cleaning pig can increase transportation efficiency of pipeline, save energy, prolong use life of pipeline and provide reliable automatic control.
Structure features of vertical & horizontal quick opening closure:
1 There is no opposite rotating between sealing surface of closure and sealing ring; the whole system has better sealing effect;
2 Three-petal clamps reduce length of opening screw, which makes the switch more flexible;
3 The bearing capacity area of teeth is simultaneously enlarged; it is more suitable for the gas pipeline of high-pressure and large caliber; there is no welding part at main bearing position;
4 There is function of secure self-locking.
Opening process of quick opening closure:
1 Open the air release valve and exhausting valve of the container where the closure is installed to reduce the pressure in the container to be zero;
2 Use the spanner to rotate the screw to enlarge internal diameter of three-petal clamps tightening ring; stop rotating screw when the internal diameter of tightening ring is larger than the external diameter of closure; and at this time the tightening ring separates from the closure seat and cover;
3 Pull the handle with hand and open the quick opening closure.
Closing process of quick opening closure:
1 Cover the antirust grease (glycerol) after completely clean sealing surface, sealing groove and dirt in the pressing rings;
2 Close and push the closure tightly;
3 Use the spanner to rotate the screw anticlockwise; press the closure cover;
4 Install the safety interlock mechanism.
The launchers & receivers, produced by shenyang wensheng company, is mainly used in the industries of petroleum, chemical industry, electrical power and metallurgy to clean the pipeline, remove wax and descaling.
Main application of launchers & receivers:
The launchers & receivers are mainly used to quickly launch or receive the pig while working in the industries of petroleum, chemical industry and natural gas. The pig will be quickly launched during the project of regular cleaning, cleaning dust and descaling of sewage pipeline.
Features of launchers & receivers:
It has simple structure and convenient operating. The pig can be installed into the pipeline quickly and safely because of the used quick opening closure; there is also security device which is reliable. The process of launching and receiving the pig can be directly indicated through installing the indicator.
