2)Appearance quality: cracks ,folding, rolling, folding, scarring, bed separation and hair pattern are not allowed.
3)Performance:high durable strength ,high Anti-oxidation corrosion ,good organizational stability . High-pressure boiler tubes often used in high temperature and high pressure conditions, under the effect of the high temperature flue gas and steam ,the oxidation and corrosion will occur ,so the pipe must have those performances.
4) High Pressure Boiler Tube is mainly used to manufacture high-pressure and high pressure boiler super-heater tubes, re-heater tube, airway, the main steam pipe, etc.
