Kufotokozera Kwachidule:

Gawo ili la European Standard limatchula zaukadaulo woperekera magawo oziziritsa opangidwa ndi welds, magawo opanda dzenje a mawonekedwe ozungulira, masikweya kapena amakona anayi ndipo amagwira ntchito ku magawo amphako omwe amapangidwa ozizira popanda kutenthedwa pambuyo pake.

Cangzhou Spiral Steel Pipes Group Co., Ltd imapereka gawo lopanda kanthu la mipope yachitsulo yozungulira.

Kuyesedwa kwa Hydrostatic

Utali uliwonse wa chitoliro uyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe idzapangitse mukhoma wa chitoliro kupsinjika kosachepera 60% ya mphamvu zokolola zosachepera zomwe zafotokozedwa kutentha.Kupanikizika kumatsimikiziridwa ndi equation yotsatirayi:
