7 pipes canfill a water tank in 6 hours Find the time required for 9 pipes to fill up the tank?

If 7 pipes can fill a water tank in 6 hours, then 1 pipe would take 7 times 6 or 42 hours. Take 42 and divide by 9, and you get 4 2/3 hours. That is the time it would take for 9 pipes to fill the tank.


How do you differentiate different types of pipes?

1.If we divide the pipes according to the production method, the main types of pipes include seamless pipes, extruded pipes, top pipes and so on. Seamless pipes also include hot-rolled and cold-rolled, which are different from each other. 2.If divided according to the shape, can also be divided into simple and complex, simple steel pipe is mainly round, square, triangular, etc., complex is mainly a variety of shaped, mainly double convex steel pipe, double concave steel pipe, melon... 3.If divided according to the wall thickness, can be divided into thin-walled and thick-walled, the naked eye will be able to see the difference between thin-walled and thick-walled. If we divide it according to the usage, it can be divided into pipe, mechanical pipe, chemical pipe, equipment pipe, etc. Different types of pipes are used in different situations, so you need to choose the right pipe according to the situation.

Municipal Construction​ HDPE Double Wall Corrugated Pipe, Steel Reinforced HDPE Spiral Corrugated Pipe, Polyurethane Insulated Pipe HDPE, Steel-Plastic Composite, Polyurethane Insulation HDPE Corrugated: Varies by spec; Insulated Pipe: DN50-100: RMB 50-150, DN150-300: RMB 150-300 HDPE: 50+; Insulated Pipe: 30-50 Good drainage, high ring stiffness, thermal insulation/energy-saving, easy installation. District Heating​ Prefabricated Polyurethane Insulated Pipe, Steel-Sleeve-Steam Insulated Pipe Steel Carrier Pipe + PU Foam Insulation + HDPE Outer Casing DN50-100: RMB 50-150; DN150-300: RMB 150-300 30-50 Very low heat loss (~25% of traditional pipes), direct burial, saves space. Notes: Material Comparison: HDPE/PE Pipes:​ Flexible, corrosion-resistant, lightweight, easy jointing. Suitable for trenchless installation. Steel Pipes:​ High strength, high pressure capacity, but require anti-corrosion treatment. Heavier. Galvanized Pipes:​ Zinc layer provides cathodic protection, good corrosion resistance, but poorer weldability. Insulated Pipes:​ 3-layer structure (carrier, insulation, casing). Excellent thermal insulation and energy efficiency. Cost Factors:​ Prices are market references. Final cost depends on specifications, wall thickness, order quantity, and logistics. HDPE pipes are typically priced per meter, while galvanized pipes are often priced per ton (e.g., ~RMB 3,965/ton for DN100). Service Life:​ Actual lifespan depends on installation quality, environmental conditions, medium characteristics, and maintenance level. Anti-corrosion steel pipes and HDPE pipes perform better in corrosive environments. Qingdao Haodeboer Products:​ The company manufactures a wide range, including Plastic-Coated Composite Steel Pipes, Steel-Plastic Composite Pipes, 3PE Anti-Corrosion Steel Pipes, Insulated Pipes, and HDPE/PE Pipes, allowing for optimal selection based on specific project requirements.
