（2） Peryòd popilarite 60-70s 20yèm syèk la

Endistri asye tiyo Lachin nan te vulgarize ak devlope nan yon sèten limit pandan peryòd sa a. Premye a tout, sou Me 1, 1960, Shanghai Non . 1 fè ak plant asye bati yon Φ100mm otomatik tiyo woule moulen ki fèt ak manifaktire pa teknisyen Chinwa ak referans a fè Anshan ak asye Φ140mm otomatik tiyo woule moulen.
Nan 1963, Beijing Shijingshan Iron ak Steel Plant (kounye a Shougang) jijman - pwodwi yon φ89mmx2.5mm otomobil transmisyon tib arbr pou Changchun otomobil faktori sou Φ102mm rezistans a soude inite tiyo, ki fòtman sipòte devlopman nan peyi Lachin nan otomobil. Depi lè sa a, Shanghai asye tiyo faktori ak lòt inite yo te itilize pwòp yo segondè {{6} An 1970, yo te elimine soude gaz manyèl Lachin nan ak altène machin aktyèl tiyo soude yo te elimine.
Imedyatman, konsepsyon an jeneral nan Φ76mm atelye tiyo asye san pwoblèm ak Φ76mm atelye tiyo soude te konpile pa òganizasyon eta a ak ankouraje nan tout peyi a. Estrikti a nan ekipman yo itilize nan konsepsyon an se relativman senp, ak jeneral mekanik ak elektrik ekipman manifakti plant yo ka manifaktire, ak mwens envestisman, ki se apwopriye pou sitiyasyon aktyèl la nan peyi Lachin nan tan sa a. Kòm yon rezilta, Anyang, Wuxi, Changzhou, Beijing, Tianjin, Jinxi, Guangzhou, Qingdao, Zhangjiakou ak lòt kote yo te pwodwi successivman rezistans tiyo soude ak tiyo asye san pwoblèm. Teknoloji pwodiksyon tiyo an asye orijinal prezante nan Inyon Sovyetik la te lajman ankouraje nan peyi Lachin. Although these equipment are not so advanced in technology and lag behind the international level at that time, the popularization of these steel pipe manufacturing technologies and equipment in various parts of the country has provided much-needed pipes for China's national economic development and production and construction, and at the same time, it has also improved the technical quality of China's steel pipe manufacturing employees, which has laid a solid foundation for technological progress and production development since then.
