3. Ọ bụrụ na oge owuwu pipeline dị ogologo, weldable mgbochi nchara agba nwere ike na-ese na iferi metal nke ọkpọkọ ọgwụgwụ iji gbochie 3PE mgbochi corrosion oyi akwa si warping n'ihi corrosion n'oge nchekwa.

4. Jikwaa nke ọma na-egweri àgwà nke ịgbado ọkụ nke echekwara na njedebe ọkpọkọ.N'èzí nke polyethylene groove na weld bụ otu ihe ahụ dị ka akụkụ ndị ọzọ nke ọkpọkọ ahụ.Debe ntụ ntụ epoxy ogologo karịa 20mm iji gbochie ala nke ntụ ntụ epoxy na weld ka ọ ghara ibu ụzọ mebie ya ma mee ka oyi akwa mgbochi corrosion 3PE.

Ekwesịrị ịṅa ntị na egweri ọkpọkọ ọkpọkọ:

1) Site na mmalite nke ịgbado ọkụ na-egweri na polyethylene chamfer, a ga-enwe akụkụ dị larịị nke polyethylene oyi akwa nke 10-20mm na-enweghị oke weld elu na otu ihe ahụ dị ka ọkpọkọ ahụ iji hụ na extrusion na njikọ nke polyethylene. uzo na ọkpọkọ njedebe àgwà.

2) Mkwado nke weld seam mgbe egweri kwesịrị ịdị na-ekpo ọkụ dị ka o kwere na ọkpọkọ ahụ, na e kwesịghị ịbụ ihe doro anya nkwado iji gbochie epoxy ntụ ntụ na-egbu maramara mgbe egweri chamfer nke polyethylene oyi akwa.

3) Chamfer nke elu na-eyighị akwa nke weld na akụkụ ntụgharị nke ebe a na-edozi kwesịrị ịdị ka chamfer nke oyi akwa polyethylene (≤30°) nke mere na ike mpịachi nke roller squeeze nwere ike ịpịa oyi akwa polyethylene iji gbochie oyi akwa polyethylene ka ọ ghara ịghagharị n'ihi nrapara na-adịghị mma nke oyi akwa mgbochi na-emebi emebi na uzo.
