Anticorrosion pipeline safety technology


 

Anticorrosion pipeline safety technology 
 
Pipe rust anti-corrosion safety the technical disclosure construction technical disclosure: construction technical disclosure content:
 
1.
Rust corrosion engineering part of the construction according to the design drawings and related specifications.
 
Rust grades determine: rusting grade specification ground pipeline pipe surface treatment should for St2.5 class. Uses sand-blasting. Sandblasting used compressed air should be dry and clean, and shall not contain oil and water, and inspection may use the following method: the white cloth and white paint target plate placed in a stream of compressed air 1min its surface with the naked eye without oil water and other stains. Sandblasting grit quartz sand should be dry and clean, free of grease and debris; moisture content should be less than 1%. Quartz sand degrees: all through the 7 mesh through 45 mesh, 20 mesh sieve shall not be less than 40% margin.
 
Sand-blasting, the steel surface should be free of grease and dirt visible, and there is no oxidation, rust, paint coatings and foreign matter, any remaining traces should only be dotted or striped slight stain. The metal surface was uniform roughness.
6. Within 2 hours after the pipeline rust self-qualified notify the supervising engineer for inspection, after passing the painting process. Examination of the surface treatment, you should fill out the inspection results table.
 
Brushing primer tube at both ends of each stay 50-100mm without painting. Small portion of the pipe can be installed with artificial mechanical blasting, priming, residual, but stay out of all welds must be according to the above requirements, in antiseptic treatment after the pressure test. Different material pipe the pornographic standard brushing primer should distinguish, and transferred to the corresponding signage material yard. 8. The anticorrosive before pipe surface must be dry before a film after hard work be painted under a paint. Painting or roller layer should criss-cross, each layer reciprocating, Tuyun so far; shall not leak spreads, the total coating thickness and number of coats should meet the design requirements, the surface should be smooth and no trace of the same color. The construction safety  content: (a helmet, goggles, masks, etc.). Enter the construction site must Peidai Lao Bao supplies.
 
2
The job required nighttime construction workplaces shall be provided with adequate lighting, and a qualified electrician on duty at the scene ready to deal with electricity and lighting. 3 blasting operations, in addition to blasting operations staff, and the rest do not have to close to the operating point for near specific slogans or gestures must notify workers suspended operations until the operation is stopped before close. Pipes placed set of anti-rolling facilities, prevent rolling wounding.
 
5. Handling anti-corrosion material and pipeline anti-corrosion, non-pyrotechnic prohibited fire. And configure a sufficient number of fire extinguishers.
 
Construction ambient temperature of 15 ℃ -30 ℃ appropriate, relative humidity should be less than 85%, in case of rain, fog, windy weather may not be constructed.
 
Prohibited at the construction site play slapstick, prohibited the construction site toilet. Construction site equipment placed unified and orderly, rational layout of the erection of wire, non Luanche the wires, mess hanging lamp. 8 non off-site, sleep Gang and drink posts.
