With the continuous development of municipal construction, higher and higher requirements have also been put forward for the construction technology and construction quality of pipelines. For the external anti-corrosion of buried steel pipes, we have eliminated the external anti-corrosion of petroleum asphalt and uniformly used epoxy coal. Asphalt anti-corrosion steel pipe. The advantages of using epoxy coal tar pitch anti-corrosion steel pipes are: 1. It has the advantages of good coal tar pitch, good water resistance, excellent rust resistance, and bacterial erosion resistance, as well as tough epoxy resin paint film, good adhesion and high mechanical strength. Features. 2. The film-forming coating has relatively stable chemical resistance, electrical insulation, microbial erosion resistance, and seawater resistance. In particular, the water absorption rate is small, and it is far more resistant to microbial erosion than petroleum asphalt. 3. Long service life. In order to correctly use epoxy coal tar pitch anti-corrosion steel pipes for buried steel pipes, ensure the quality of the anti-corrosion layer and prolong the service life of buried steel pipes, construction should be carried out in strict accordance with the following requirements: 1. Construction technical requirements 1. Steel pipe surface treatment. Generally, the surface of the steel pipe has oxide scale, rust, oil pollution, dust, etc. If it is not treated, it will directly affect the adhesion of the coating. The surface can reach SaZ (l/2) level (with the naked eye, there are obvious hair lines on the surface), and the primer should be applied within 6h after removing the rust. 2. Apply primer. The primer can be applied with a roller brush or a paint brush. The primer should be applied as thinly as possible, generally 30 m to 5 m, and it should be noted that the paint film is uniform and does not leak.

Pargîdanî pêbaweriya kalîteyê ya “bingeha yekparebûnê, kalîteyê-rêveber” digire, “rêveberiya yekitiyê, xîret û pragmatîzm, rêveberiya zanistî” wekî ruhê pargîdaniyê, konsepta kirrûbirrê-bazirganî, xerîdar-navendî digire. Ew pejirandina pergala rêveberiya kalîteyê ISO9001-2008 derbas kiriye, û ji hêla Wezareta Avakirinê ve wekî hilberek pêşniyarkirî ji bo projeyên avakirina endezyariyê hatî navnîş kirin. Ew wekî pargîdaniyek hilberînê ya destnîşankirî ji hêla Komeleya Drainage ve hatî pejirandin. Di heman demê de wê gelek xelatên wekî “Belgeya Hilbera Nû ya Klavyeya Neteweyî” ku ji hêla pênc wezaret û komîsyonên neteweyî ve li devera Chengdu hatî weşandin, bi dest xistiye. Berhemên pargîdaniyê qalîteya bilind, pêbawer û hawîrdorparêz in, û bi berfirehî di dabînkirina avê û avdanê de, sprinklerên agir, tunelên otobanê, veguheztina rêwîtiya sivik, navendên trênê yên bilez, kanên komirê, kîmyewî, hêza elektrîkê, neft, gaza sirûştî, ava gerîdeya pîşesazî û pîşesaziyên din. Pargîdanî bala xwe dide lêkolîn, pêşkeftin û hilberîna pîşesaziya kincê, da ku hilber ji bo qadên cihêreng maqûl bin. Performansa hilber, kalîte û nîşaneyên teknîkî li hundur û derveyî welêt gihîştine asta asta bilind, û dikarin li gorî hewcedariyên xerîdar karûbarên piştevaniya birêkûpêk peyda bikin.
