Is PVC pipe in New York city legal?
I work in industrial HVAC for over 35 years in New York City. I was informed by an engineer that all plastic pipe is illegal in New York City because the Fire Department deemed that plastic pipe gives off toxic fumes when exposed to fire.
Do you have any recommendations on water supply pipes?
Pipeline Selection Guide for Different Applications qdhaodeboer com APPLICATION SCENARIO RECOMMENDED PIPELINE TYPE PRIMARY MATERIAL COST REFERENCE (PER METER) SERVICE LIFE (YEARS) KEY CHARACTERISTICS Mining Plastic-Coated Composite Steel Pipe, Mining Pipe Steel Pipe + Epoxy Resin/PE Coating Plastic-Coated: RMB 35-120 20-30 Abrasion-resistant, corrosion-resistant, impact-resistant. Suitable for mine drainage, ventilation, etc. Water Supply HDPE/PE Water Supply Pipe, Plastic-Coated Composite Steel Pipe HDPE (PE100/PE80), Steel-Plastic Composite HDPE: ~RMB 10 (DN20), ~RMB 50 (DN100); Plastic-Coated: RMB 35-120 HDPE/PE: 50+; Plastic-Coated: 20-30 Corrosion-resistant, smooth inner wall (prevents scaling), meets drinking water hygiene standards. Gas Transmission PE Gas Pipe, 3PE Anti-Corrosion Steel Pipe Special PE Compound, 3-Layer Polyethylene Coated Steel 3PE Steel Pipe: RMB 20-56 PE Gas Pipe: 50+; 3PE Steel Pipe: 20+ Resists slow crack growth, low permeability, corrosion-resistant, high safety. Oil Pipeline 3PE Anti-Corrosion Steel Pipe, Plastic-Coated Composite Steel Pipe 3-Layer PE Coating, Steel-Plastic Composite 3PE: RMB 20-56; Plastic-Coated: RMB 35-120 20-30 High pressure resistance, corrosion-resistant, impact-resistant.

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.
How can we measure density of PVC compound?

Are pipes measured on the inside?
both ID inside diameter and OD outside wall thickness is determined by sch 40 ect the higher the number the thicker the wall pressure pipe should be a higher rating c900 PVC can go to 200 psi ductile and steel up to 600 psi non pressure pipe is a sch 35 usually
Does hcl acid react with PVC?
Depends on what king of PVC and what's the concentration of the acid. For example the 35% HCl damages the flexible PVC on 50°C, but the rigid PVC not... (The flexible PVC become rigid I think.)

What is flow of water through a half inch copper pipe at 35 psi?
The flow of water through a half-inch copper pipe at 35 psi can be estimated using the Hazen-Williams equation or similar hydraulic formulas. Generally, a half-inch pipe can deliver approximately 5 to 10 gallons per minute (GPM) at that pressure, depending on factors like pipe length, fittings, and flow conditions. For a more precise calculation, additional parameters such as the specific setup and any friction losses would need to be considered.
