selection of high quality raw material processing, high hardness, strong compressive resistance, durable.
2. Smooth inside:
transparent, no scaling, dense, no water leakage, transparent pipe wall, smooth water flow.
3. Anti-cracking compressive:
not broken, long lifespan, corrosion resistance. 4. Thicken wall:
waterproof and explosion-proof, side thickening is more firm, quality is more assured.
