Mukugadzirwa kwepombi kureba, nemitsara yesimbi inoverengera chikamu chikuru, mumamiriro ezvinhu akajairika, 35% kusvika 40% yekudyara kwepombi yemutsara inoverengera huwandu hwemari yeprojekiti.Nzira yekusarudza mutengo unonzwisisika, kushanda kwakanakisisa kwepombi kunonyanya kukosha, chisarudzo chakanaka chekuchengetedza pombi yekuvaka mari, kufambisa kuvaka uye kushanda kwakachengeteka kwepombi yepombi ine simba rinokosha zvikuru.LSAW simbi pombi mukana inoita kuti inogona kushandiswa zvakanyanya kune yayo yakasarudzika kureba-kure oiri uye gasi mapaipi.

Zvakanakira LSAW simbi pombi ndeiyi:

(1) pasina iyo unwind maitiro, base base zvinhu indentation, kukwenya zvishoma.

(2) iro divi risiri iro, rakatsvetwa, uye zvimwe zviri nyore-ku-diameter perimeter control, yakanakisa welding mhando.

(3) kubviswa kwekupisa hakupo nekusarira kunetseka mushure mekushushikana.

(4) nekuti iri tambo yakatsetseka, weld ipfupi, njodzi shoma yekuremara.

(5) mushure mekuwedzera, kurongeka kwepombi geometry inovandudzwa zvakanyanya kufambisa pa-saiti welding.

(6) yemusono wakatwasuka, kushomeka kunokanganisa kunaka kweanopesana necorrosion coating materials.
