These bottom loading arms are particularly designed for the transfer of cryogenic media such as liquefied natural gas (LNG), ethylene, etc.

Specifications

Transfer medium: liquefied natural gas (LNG), cryogenic ethylene, liquid oxygen, and other cryogenic media
Nominal diameter: DN50～DN80
Design pressure: -0.06MPa～2.0MPa
Design temperature: -196℃～ 60℃
Pipeline material: 304L/316L stainless steel

Features

Gaseous phase arm for vapor recovery, liquid phase arm for liquid transfer;
Cryogenic swivel joint is designed with double ball race, and provided with nitrogen purging system to keep raceway dry and prevent the swivel joint from freezing in cryogenic applications;
Swivel joints are precisely processed and assembled, providing the loading arm with great reliability and low resistance, therefore allowing for one-person operation;
Each loading arm is put through rigorous strength testing, air tightness testing, cryogenic testing and leakage testing to guarantee the high quality and reliable performance;
Pressurized pipeline can be added to speed up tanker loading and unloading;
