沈阳瑞华自限温伴热带/电伴热 self regulating heating cable/heat tracing cable

防冻防护（低温储罐）

瑞华电伴热可以防止安装在地面的低温储罐（例如装有液化天然气、氨水或其他低温液体的罐体）下方的地面出现冻胀现象。 坚固、可靠的电缆系统可使罐体下面的地面免于因冻胀而造成罐底或罐壁磨损甚至破裂。

RUIHUA self regulating heating cable provides full design capabilities for the prevention of frost heave under grade mounted cryogenic tanks, tanks or vessels containing LNG, ammonia, or other low temperature liquids. Rugged, reliable cable systems prevent the ground below the tank from freezing and rising to cause the tank floor or wall to weaken and rupture.
