As an important category of modern engineering plastic pipes, HDPE (high-density polyethylene) pipes have been widely used in municipal administration, construction, agriculture, industry and other fields due to their excellent physical and chemical properties. Among them, 160mm diameter HDPE pipes occupy an important position in various engineering projects due to their moderate pipe diameter specifications. This specification of pipes can not only meet the needs of medium flow transportation, but also have good economy and construction convenience, becoming one of the mainstream products in the market.
Strong corrosion resistance: can resist the erosion of most chemical substances, with a service life of more than 50 years
Good flexibility: can adapt to a certain degree of foundation settlement, excellent seismic performance
Good hydraulic characteristics: smooth inner wall, small friction coefficient, stable conveying capacity
Reliable connection: hot-melt connection is adopted to form an overall pipeline system without leakage risks
Light weight: only 1/8 of the same specification steel pipe, convenient transportation and installation
Environmental protection and safety: non-toxic and odorless, in line with the sanitation standards for drinking water transportation
Municipal engineering: urban water supply network, drainage system, reclaimed water reuse, etc.
Agricultural irrigation: large and medium-sized farmland irrigation systems, water-saving irrigation projects
Industrial use: chemical medium transportation, mine tailings discharge, cable protection, etc.
Construction engineering: building water supply and drainage, ground source heat pump system, etc.
The price of 160mm HDPE pipe is affected by multiple factors, forming a complex market pricing mechanism. Understanding these influencing factors will help buyers make more reasonable decisions.
1. Raw material cost factors
Raw materials are the basic factor that determines the price of HDPE pipes, accounting for about 60-70% of the total cost:
Polyethylene resin price: closely related to the fluctuation of international crude oil prices, PE100 grade raw materials are about 10-15% higher than PE80 grade
Additive cost: including antioxidants, UV absorbers, masterbatches, etc. High-quality additives can improve product performance but increase costs
Differences in raw material sources: There is a price gap between imported raw materials and domestic raw materials, usually 5-8%
2. Influence of production process
Different production processes lead to differences in product quality, which in turn affects prices:
Extrusion equipment: The price of pipes produced by imported production lines is 10-20% higher than that of pipes produced by domestic equipment
Process control: The quality of products using online monitoring and automatic control systems is more stable, and the price is increased accordingly
Structural design: Double-wall corrugated pipes save materials but have complex processes compared to solid wall pipes, and the price difference is between 5-10%
Technological innovation: Products using new technologies such as nano-modification have performance advantages, and the price can be 15-25% higher
3. Market supply and demand relationship
Market supply and demand directly affect price fluctuations:
Regional differences: Prices in areas surrounding production bases are usually lower, and transportation costs increase by 5-8%
Seasonal changes: Demand is strong during the construction peak season (March-June, September-November), and prices may rise by 3-5%
Project scale effect: Centralized procurement of large-scale projects can obtain a 3-10% price discount
Competitive landscape: Price competition is fierce in areas with dense manufacturers, and the price difference can reach 8-12%
4. Brand and service added value
Brand value and service content constitute an important part of the price:
Premium for well-known brands: First-line brands are 15-30% higher than ordinary brands
Certification qualifications: Products with ISO, CE and other certifications are 5-15% more expensive
Technical services: Suppliers who provide value-added services such as design and installation will have their quotations increased accordingly
1. Classification by product type
Ordinary solid wall pipe: basic price, widely used in general water supply and drainage projects
Double wall corrugated pipe: 5-15% higher price than solid wall pipe, mainly used in drainage system
Wire mesh skeleton pipe: 20-40% higher price, suitable for high pressure transmission scene
Special purpose pipe: such as gas pipe, chemical pipe, etc., the price is 25-50% higher than ordinary pipe
2. Classification by quality grade
National standard products: meet national standards, moderate price, market mainstream
Enterprise standard high quality products: higher internal control standards of enterprises, 10-20% higher price than national standard products
Imported brands: internationally renowned brands, 30-60% higher price than similar domestic products
Recycled material products: use some recycled materials, 15-25% lower price, but performance is limited
3. Classification by application field
Pipes for municipal engineering: higher requirements, 10-15% higher price than ordinary pipes
Pipes for agricultural irrigation: focus on economy, relatively low price
Pipes for building water supply and drainage: various specifications, large price range
Pipes for industrial use: special requirements, generally higher prices
As an important engineering material, the price formation mechanism of 160mm HDPE pipes reflects the complexity of the market economy and the stage characteristics of industry development.
