Dingyang seam pipe ngu ai gaw, pipe galu ai hte maren sha, seam langai mi hkawm ai weld galaw da ai steel pipe re. Steel plate (sh) strip hpe grup yin hku galaw nna, dai hpang lahkawng maga de shinggrup da ai. Ndai pipe hpe lata la ai madang hte chyam dinglik ai madang gaw bungli hte htap htuk ai shaloi, n-gun n law ai hka htung ni, npawt nhpang npawt nhpang ni, nta gap ai pipe bungli ni, sau (sh) wan sau bungli masing ni a matu lang ai.
Dai zawn re ai n-gun rawng ai pipe hpe galaw shapraw ai lam gaw, n-gun rawng ai size law law a matu lajang na matu asan sha rai nga ai. Pipe kaji hte kaba ai pipe ni a matu high-frequency welding hpe lang chye ai, n-gun kaba ai pipe ni a matu gaw submerged arc welding hpe lang ai. Weld line hpe n sa shi yang, jep yu, trim galaw, chyam yu mai ai. Ndai arai hpe coating, beveled, expand, shing nrai, masat da ai galu de gang je kau mai ai. Site lang na matu, mari ai wa gaw diameter, bunghku n-gun, n-gang grade, weld ntsa, jahtum hkyen lajang ai lam ni hpe jep yu ra ai. Dai lam ni hpe asan sha chye lu ai shaloi, ndai arai gaw hka, gawgap ai lam, hte general steel pipe project law law hta hkrak nga ai.
