Acid Resistance Epoxy Coated Ductile Iron Pipe For Underground Coal Mine
Mine pipe refers to a product specially developed for special underground environmental conditions, which has the advantages of flame retardant, antistatic, corrosion resistance, long service life and strong safety. It is mainly used in five systems: mine drainage pipe (KS), mine grouting pipe (KJ), mine positive pressure air pipe (KFZ), mine negative pressure air pipe (KFF), mine gas drainage pipe (KW).

Chemical corrosion resistance, weathering resistance and aging resistance are very high: the coating can prevent metal oxidation, and has the corrosion resistance of acid, alkali and salt. The product has excellent anti-aging performance, and its service life is much higher than other pipes. The product can be painted with flange to ensure the anticorrosion effect of the whole pipeline.
Flame retardant and antistatic performance is good: flame retardant and antistatic indicators meet the requirements of underground gas drainage pipe indicators. Flame retardant: The arithmetic average of flameless combustion time is less than 3S and the maximum is less than 10s; the arithmetic average of flameless combustion time is less than 20s and the maximum is less than 60s. Antistatic: internal and external surface resistance ≤1.0×106Ω.
Connection modes are diversified and easy to construct: Flange connection, fast joint connection, socket connection, bimetal connection and butt welding connection can be adopted for the products. Connection modes are diversified and installation is convenient.
Internal and external coatings can be made of different materials or colors according to customer's environment and requirements.
