1、 Purpose and scope of pig:

1. Pig for construction stage

(1) Remove sundries and tools left by construction in the pipeline. (ordinary cup pig)
(2) Check the dents, deformation and drift diameter of the pipeline. (caliper cup pig)
(3) Remove the weld beading and floating rust at the weld junction on the inner wall of the pipe. (steel brush cup pig is also called rust remover)
(4) Before the pipeline pressure test, remove the air in the pipeline. (ordinary cup pig and straight plate cup mixed pig)
(5) After the pressure test of the pipeline, drain the residual water in the pipe. (straight plate bidirectional pig and straight plate cup mixed pig)

2. Pig for pipeline operation

(1) Isolate the conveying medium. Especially in the process of producing oil sequential transportation. (ordinary cup pig or two-way straight plate pig)
(2) Wax removal of a crude oil pipeline. (steel brush cup pig, soft descaler)
(3) Remove solid deposits in the pipeline. It can also improve pipeline operation efficiency. (ordinary cup pig, straight plate cup mixed pig)
(4) Remove the condensate from the natural gas pipeline. (ordinary cup pig, straight plate bidirectional pig, and straight plate cup mixed pig)
(5) Pigging before pipeline repair. (ordinary cup pig, steel brush cup pig, or straight plate cup mixed pig)
(6) Pipeline descaling. (soft descaler, soft pig, ordinary cup pig, straight plate cup mixed pig)

3. Special purpose pig (intelligent detection pig)

In the process of pipeline operation, we require the pig to be able to detect both the pipe wall dent and deformation. At the same time, we can also detect defects such as pitting and cracks

2、 Composition of pig

Electronic pig includes electronic positioning transmitter and pig cup. There are also pig body, flange, backing ring, bolt and other parts. Ground receiving instruments are also used. Ball indicator and electronic positioning receiver.

3、 Type of Pipe Line Cleaner

2. Polyurethane soft pig. Series soft pig. Also series of soft descalers. Series software enhanced descaler.
3. Standard cup electronic caliper pig. Series caliper pigs. Series caliper combined (mixed) pig.
4. Straight plate and cup mixed pig. And straight plate two-way pig. Straight plate cup mixing pig.
5. Special purpose electronic pig. Series polyurethane pressure bypass electronic pig. Also series polyurethane variable diameter electronic pig. Series polyurethane magnetic electronic pig.

4、 Working principle of pig:

According to the specific situation of the pipeline and the purpose of pigging, users can choose different series of pigs. The pig carries an electronic transmitter. Thus forming an elastic seal between the cup and the inner wall of the pipe. So it runs along the pipeline under the pressure difference generated by the pipeline medium. It relies on the pig itself and the tools it carries to squeeze and scrape. And it cleans the scale, wax and deposits (sundries) in the pipeline by flushing. During the operation of the pig, the electronic transmitter continuously sends out pulse signals. So that the ground instrument can receive. This enables operators to understand the operation of the pig in the pipeline. Therefore, it realizes the effective connection between the pig in the pipeline and the ground-receiving instrument and monitoring personnel. And it provides an accurate and reliable guarantee for safe operation.

1. Technical parameters:

The radius of curvature of the passing elbow: R ≥ 1.5D (nominal diameter of the pipe)
Allowable pipe deformation: △≤ 15% d (pipe nominal diameter)
Cup interference: 2 ~ 5% (7% is allowed for special pipe diameter)
Interference of straight plate: support plate 0%, sealing plate 2 ~ 3%
Medium and ambient temperature: – 20 ℃ ≤ t ≤ 100 ℃

2. Model selection of series pig and instrument:

◆ Polyurethane cup electronic pig

It contains a metal steel body (1Cr18Ni9Ti material below DN250). There are also electronic transmitters and polyurethane (rubber) cups. It can be used for pigging and cleaning various new pipelines before they are put into production. There is also the medium isolation of the exhaust and mixed transmission pipeline before the hydrostatic test. Gas discharge of combustible media such as natural gas and gas pipelines. It can remove stones, tools, and other sundries left in the pipeline during pipeline construction.

◆ Polyurethane cup electronic rust remover

It comprises a metal steel body and an electronic transmitter. There is also polyurethane (rubber) cups, discs, and steel brushes. It can mainly remove the rust on the inner surface of the pipeline before internal coating. Pipe Line Cleaner can also remove weld beading and dirt. At the same time, it is also suitable for wax removal construction of oil pipelines. In addition, it has good rigidity, strong passing capacity, and a good rust-removal effect.

◆ Polyurethane bidirectional electronic pig

It comprises a metal steel body and an electronic transmitter. There are also polyurethane support plates,s, and sealing plates. It has the functions of two-way walking, cleaning, isolation, and water blocking. It is especially suitable for pipelines that are inconvenient to open after being blocked. Such as submarine pipelines and crossing pipelines. It has the characteristics of good sealing and thorough cleaning.
