1、GENERAL INFORMATION

The pipeline does not stop loses the opening, the trap series equipment is composed of the main engine and the auxiliary engine two kind of series, the main engine series is by the opening machine, the trap, the hydraulic pressure stands with the under tamper four kind of different functions, the different model and the specification equipment corresponds mutually necessary is composed. The auxiliary engine is by the continually box series (by-pass opening case, trap opening case, seals off case, under to stop up box, the opening knife series (by-pass opening knife, trap opening knife), to clamp the plate valve series, the trap tube series with the caliber which corresponds to be composed continually), it is (opens by-pass hole or trap hole) according to the different operating type and the work caliber matches the different main auxiliary engine. The user may refer to the necessary table according to need to select.

2、USE AND CHARACTERISTIC

This series equipment is a set feeds specially the pipeline opening, the trap construction work equipment. The main application does not stop the transportation medium in the pipeline, not depressurizing, guaranteed that in pipeline’s normal operation’s situation, carries on the service, the emergency repair to the pipeline, to affix the by-pass, the replacement the valve, the replacement length of pipe, and the pipeline changes course partially with the processing pipeline interior breakdown and so on complete set of equipment.

Use this equipment to change the tradition to stop loses, the voltage dropping, to diffuse, the use open fire operating type, reduced the economic loss and to the environment adverse effect, and might avoid at night the work, reduced the manpower, the physical resource investment, enhanced the work efficiency, to reduce the labor intensity and the consumption, avoided the operating risk, enhanced the security.

3、ADAPTATION SCOPE

This complete set of equipment adapts in flammable explosive, virulent harmful liquids, the gas and so on crude oil, chemical industry, liquified petroleum gas, coal gas, natural gas transportation pipeline and the urban water supply heat supply pipeline’s belt presses does not stop loses the construction work.

4、PRESSURE AND TEMPERATURE

This product adapts transports pipeline’s medium pressure and the temperature:

1、KKJ Hot tapping machine

KKJ hot tapping machine is the main equipment of this series of products，it used for cutting holes and sealing hole by-pass。

KKJ hot tapping machine main performance and technical parameters

2、FDQ trap

The FDQ trap is realizes stops loses the trap the major installation, it is in first and the corresponding main auxiliary engine coordinates after the opening machine starts out the interruption hole by the trap match corresponding auxiliary engine to realize the trap. It corresponds to 150, 300, 500 hot tapping machine, fuselage three kind of specification – FDQ150, FDQ 300 and FDQ500. And 150, 300 for manual, 500 to rise and fall the fluid to move, its performance and the technical parameter see the next table.

trap main performance and technical parameters

(1) To repair or update in the ends of pipe sections were welded with pressure fittings and flanges for the equilibrium pressure plugging holes

(2) In the welded pipe fittings and flanges clogged valves and even install plywood boxes and tapping machine, were broken pipe openings and opening balance
　　　　　　　　

(3) Remove tapping machine, install blocking even the box and occluder temporary bypass connection, connectors pressure balance pipe, pipe sections at both ends of the occluder manipulation, will implement the expansion cylinder block. Then pigging, broken pipe.

(4) Recovery pipe, as the pressure balance, withdraw the expansion cylinder, close the plywood valve, remove the temporary bypass pipe and the balance, removal of the occluder, install blocked. Remove plywood valve, pipe fittings and flanges in the jam were stamped blind, the job ends.

XD PLUGGING MACHINE

When transports the pipeline to carry on the trap finished, this equipment with clamps the plate valve connection, uses in the orchid or the fitting stops up the hole.

BOX CONNECTED

Even the box connected to the main starting valve openings and the role of boards and knives into one of possession. Even the upper part of me with a model J13H-160 cut-off valves, opening operation for the emission of air and media. The explosive opening of the pipeline operations, can also make use of the valve box to even inject nitrogen protection and flange plug at home on the welding quality control, equipment to connect the sealing surface to conduct stress testing, and stress balance, and manages on to the flange jamming in the mother the welding quality, the equipment joint face seal situation carries on the pressure inspection, as well as pressure balance and so on.

WAFER VALVE

The wafer valve does not stop specially for the pipeline loses start the hole work design manufacture one kind of sampan type gate valve. It has the latus rectum in a big way, short highly, the sealing property good, the structure compact and so on the characteristics. Above JBF150, pressure rank 6.4Mpa

CUTTER

The cutter is uses the jacking cutting form, the center drill and the jacking cutting fission puts all in one load. The hilt inner cone and the drill rod coordination connects a center drill end to turn on lathe into the drill rod center spiral hole calmly to fasten the knife tube, the center drill gets up the cutting to be calm, and is equipped with a U shape in above to clamp, it was unmistakably the saddle block which cut has cancelled accurately and its extraction.

YYZ HYDRAULIC PUMP

hydraulic pump is a equipment, to provides the power supply for tapping machine and FDQ500 trap.

FLANGE JAMMING

The Flange jamming is one kind of special-purpose consumption. It is uses for to weld in must open the hole on the pipeline for to operate the hole equipment the installment to provide a fixed bearing.

DISC TRAP

The disc trap the power director which stands through the hydraulic pressure, it can seal the caulking to send in pipeline to assign the position, serves the trap purpose the equipment.

Seals the caulking

Seals the caulking is the disc trap constituent. Including parts and so on control rod head, movable support, antenna. When the hydraulic cylinder leads the control rod head enters after the pipeline, the movable support and the pipeline center forms 20° the included angle.

Flange Tee

When the pipeline carries on the trap work, this equipment uses in connecting the pipeline with to clamp the plate valve;

Waited the trap construction to finish, uses in the pipeline stopping up the hole; in convenient detector tube situations and so on medium, wax level. Is advantageous for tubes and so on elimination pipeline cleaner to clean up, the overhaul, check-out facility’s breakdown. When transports the pipeline carries on the trap work, this equipment uses in connecting the pipeline with to clamp the plate valve; waited the trap construction to finish, uses in the pipeline stopping up the hole; in convenient detector tube situations and so on medium, wax level. Is advantageous for tubes and so on elimination pipeline cleaner to clean up, the overhaul, check-out facility’s breakdown. According to different caliber configuration corresponding specification three.

Trap By-pass.

Is advantageous for tubes and so on elimination pipeline cleaner to clean up, the overhaul, check-out facility’s breakdown. According to different caliber configuration corresponding specification by-pass.

Leather Cup

The leather cup is designs the trap application the synthesis product which strengthens by the textile fiber cloth, side the guidance is specially to resist the pipeline pressure to play the rigid bracing role to use the textile fiber cloth to strengthen, three jiao parts are to realize in the tube to seal, but is the pure oil resistant rubber makes elastically, the seating cup base inlays has the packing ring, when the leather cup installs after the movable support, the cup leather packing seals up seals on the caulking the bolt hole.
