How to carry out quality inspection on pipe spool fabrication line?

In order to give full play to the advantages of pipeline prefabrication equipment and overcome the limitations of fixed pipe spool fabrication line, we have developed a movable pipe spool fabrication line, which has been used in PetroChina, Sinopec, and China National Chemical Corporation. So, what are the precautions for the quality inspection of the pipe spool fabrication line?

About the quality inspection content of the pipe spool fabrication line.

The pipe spool fabrication line consists of a work station for pipe beveling, a work station for pipe mechanical assembly, a work station for automatic pipe welding, a steel structure work station frame that can be quickly disassembled, a trolley railing system and a light rail to form a transportation system.

 

The testing items of the pipe spool fabrication line include: density, melt mass flow rate, hydrostatic pressure, ring stiffness, flatness, ring flexibility, thermal stability, volatile content, moisture content, carbon black content, carbon black dispersion, Pigment dispersion, gas component resistance, rapid crack propagation resistance component analysis, component content detection, etc.

The comprehensive performance of pipe spool fabrication line will reach a high level in China:

1. In the detailed design, China's most advanced "Pipe Manufacturing Design System" software is used to realize the rapid drawing of the pipe spool fabrication line. After the IDF interface module is configured, the design data of the PDS and PDMS design institutes can be directly shared, so a "seamless combination" is realized between design and construction.

2. In the manufacturing management, the domestic first-class "pipe manufacturing and installation management system" software is used to realize all-round information management of the entire pipe spool fabrication line manufacturing process.

3. Pipe spool fabrication line groove adopts a reliable pipeline groove mobile workbench, two of which are used for pipe groove.

4. Roller bed type pipe plasma cutting and beveling machines have been used to cut pipes and form bevels in one step through thermal cutting and processing.

5. An efficient pipe cutting band saw machine and a fixed radial pipe end beveling machine are used to cut the pipe and machine the bevel according to the working procedure.

6. The unique mobile workstation for pipe mechanical assembly in China has been used for weld assembly to mechanically assemble pipe shaft welds.

7. Cover pipe welding adopts advanced automatic pipe welding movable workstation, pipe spool fabrication line automatic welding machine is used to realize efficient automatic cover pipe welding of pipe shaft.

8. The logistics transportation adopts the light rail transportation system, the station frame and the trolley railing system. The light rail transportation system is used for long-distance mechanical logistics transportation, and the station frame is used for transportation. The overhead railing system is used for container internal and external logistics transportation.

9. The pipe spool fabrication line project has a production capacity of 3000 inches/year and a day's production capacity of 1000 inches/day, which meets the huge engineering demand for prefabricated pipelines.

How to inspect the pipe spool fabrication line?

Pipe spool fabrication line has now been widely used in all aspects of people's lives, and unqualified pipes directly affect people's quality of life and health. At the beginning of 2014, some media exposed the problem of individual companies using recycled waste to produce drinking water distribution pipes and fittings, which had a bad social impact. So how to enter the site to inspect the pipe spool fabrication line?

 

The material, specification, model and quality of the pipe spool fabrication line and pipe fittings should meet the current national product standards and design requirements.The appearance quality of the pipe spool fabrication line should not only meet the requirements of its product standards, but also the following requirements:

 

l There are no defects on the surface such as cracks, shrinkage holes, slag inclusions, folding, heavy leather, and rust or dents that do not exceed the negative deviation of the wall thickness;

l The thread surface is intact without damage, and the flange sealing surface is flat, smooth, without burrs and radial grooves;

l The gasket has no aging deterioration or delamination phenomenon, and no defects such as wrinkles on the surface.

l Inspection quantity: all inspections. Check the factory inspection report and certificate.

l Inspection method: observe and inspect.

l The size, wall thickness and allowable deviation of the pipe spool fabrication line should meet its product standards and design requirements.

l Inspection Quantity: 20% of the products of each specification and model are randomly checked by the number of pieces, and no less than 1 piece

l Inspection method: measure with steel ruler and vernier caliper.

 

For the pipe spool fabrication line belonging to one of the following conditions, sampling shall be conducted by the supervision engineer, and the inspection and re-inspection shall be carried out by a qualified inspection unit. The re-inspection results shall meet the current national product standards and design requirements.
