High-density polyethylene (HDPE) pipes are widely used in municipal engineering, agricultural irrigation, mining, chemical industry and other fields due to their excellent physical properties and corrosion resistance. This article will mainly discuss 18 HDPE pipe dimensions and prices to help practitioners in related industries to better purchase and use them.
Basic Overview of HDPE Pipes
HDPE pipes are made of high-density polyethylene materials and have excellent toughness and impact resistance. Its main advantages include:
1. Corrosion resistance: Not easily corroded by chemicals, suitable for a variety of harsh environments.
2. Lightweight: Compared with traditional materials, HDPE pipes are lighter and easier to transport and install.
3. Various connection methods: It can be connected by hot melt, electric melt and flange, etc. to meet different construction needs.
18 hdpe pipe dimensions
The actual outer diameter of 18-inch HDPE pipe is usually 460 mm (18.1 inches), and the inner diameter varies according to the thickness of the pipe wall. There are generally multiple options for the wall thickness of HDPE pipes, and common wall thickness standards include:
SDR 11: inner diameter is about 400 mm, wall thickness is about 55 mm
SDR 13.5: inner diameter is about 415 mm, wall thickness is about 45 mm
SDR 17: inner diameter is about 430 mm, wall thickness is about 38 mm
18 inch hdpe pipe price
Price is an important consideration when choosing a pipe. 18 inch hdpe pipe price is affected by many factors, including raw material costs, production processes, market demand and supply conditions. Generally speaking, the market price range of HDPE pipes is as follows:
1. Price per meter: According to market research, the price of 18 inch HDPE pipe is roughly between RMB 200 and RMB 400 per meter, and the specific price varies depending on the region, manufacturer and purchase volume. Bulk purchases usually enjoy more favorable prices. The specific price depends on the wall thickness of the pipe, the manufacturer and the purchase quantity.
2. Bulk purchase discount: Generally, bulk purchases will enjoy certain discounts and the price will be more competitive.
Factors Affecting Prices
When selecting and purchasing 18 inch HDPE pipe, the following factors that affect prices need to be considered:
1. Raw material cost
The cost of HDPE directly affects the price of the pipe. Fluctuations in crude oil prices can cause changes in the price of polyethylene resin, which in turn affects the market price of the pipe.
2. Production process
Different production technologies and equipment will affect production efficiency and production costs, which in turn affect the final market price. Although high-tech production lines have higher initial investments, they often provide advantages in production efficiency and product quality.
3. Market demand
During certain seasons or peak periods of specific projects, the market demand for HDPE pipes increases and prices may rise. Conversely, in the off-season or when there is an oversupply in the market, prices may fall.
4. Pipeline specifications
The specifications of the pipe (such as wall thickness, length, etc.) will affect its unit price. Generally speaking, the thicker the wall and the larger the diameter of the pipe, the higher the production cost and material consumption, so the price will be relatively high.
5. Supply chain factors
Transportation costs, inventory management, and the stability of the supply chain will also affect the final market price. Reasonable logistics and supply chain management can effectively reduce costs.
Application fields
18 inch HDPE pipe is widely used in:
Municipal engineering: used for water supply and drainage systems to ensure urban infrastructure construction.
Agricultural irrigation: suitable for drip irrigation and sprinkler irrigation systems to improve the utilization efficiency of water resources.
Chemical industry: suitable for conveying various chemical media, especially corrosive substances.
Mining industry: used for conveying slurry and wastewater, with good wear resistance.
In summary, 18 inch HDPE pipe has been widely used in many industries due to its excellent physical properties and applicability. Understanding its size and price is an important prerequisite for procurement and use. With the continuous development of the market, the technology and application fields of HDPE pipes are also expanding, and there will be more innovation and development opportunities in the future.
It is hoped that through the analysis of this article, it can provide valuable information for practitioners in related industries to help them make more informed decisions when choosing high-density polyethylene pipes.
