I loko o kēia wā, ua hoʻokumu ʻia kahi hoʻonohonoho o nā lako hana a me nā pono hana nānā, e kū nei i nā kūlana honua o ka Vacuum Insulation Piping System. ʻO ka hopena, ua ʻike ʻia ʻo Chengdu Holy e kekahi mau ʻoihana kinoea honua nui loa (me Linde, Air Liquide, Messer, Air Products, Praxair, BOC etc.).

Ua loaʻa iā Chengdu Holy ka palapala hōʻoia ISO9001 no ka manawa mua ma 2001, a ua nānā hou i ka palapala hōʻoia i ka manawa kūpono e like me ka mea e pono ai.
