SDR11 and SDR17 Gas Pipe

SDR11 and SDR17 are two common pressure ratings used for PE gas pipes.

SDR stands for Standard Dimension Ratio, which is the ratio of pipe wall thickness to pipe diameter. The smaller the SDR value, the thicker the pipe wall and the higher the pressure resistance of the pipe.

SDR11 PE gas pipe

SDR11 means that the wall thickness is 1/11 of the pipe diameter.

SDR11 PE gas pipe is usually used in high-pressure gas transmission system and can withstand high working pressure.

This type of piping is suitable for long-distance gas transmission, urban gas supply and industrial gas applications.

SDR17 PE gas pipe

SDR17 means that the wall thickness is 1/17 of the pipe diameter.

SDR17 PE gas pipe is suitable for medium pressure gas transmission system and can withstand moderate working pressure.

This type of pipe is suitable for gas transmission over shorter distances, low pressure gas supply and domestic, commercial and industrial gas applications.

When selecting SDR11 and SDR17 PE gas pipes, the following factors need to be considered:

Working pressure requirements: According to the specific gas transmission system requirements and design pressure, select the appropriate SDR grade to ensure that the pipeline can safely withstand the working pressure.

Pipeline length and transmission distance: Long-distance gas transmission usually requires a higher SDR grade to ensure the stability and safety of the pipeline during the entire transmission process.

Environmental conditions: Consider the special conditions of the pipeline installation environment, such as soil type, temperature changes, and groundwater levels. These factors can affect piping selection and installation requirements.

SDR11 and SDR17 PE gas pipes advantage

SDR11 and SDR17 PE gas pipes are pipe materials widely used in the field of gas transmission and supply, they have the following characteristics and advantages:

SDR11 PE gas pipe

High pressure bearing capacity: due to the smaller SDR value, SDR11 PE gas pipe has a thicker pipe wall and can withstand higher working pressure. This makes it ideal for use in high pressure gas transmission systems.

Excellent chemical resistance: SDR11 PE gas pipe has good corrosion resistance to many chemicals and solvents. This enables it to be used in a wide variety of environmental conditions, including some aggressive gas media.

Long Life and Durability: SDR11 PE gas pipe is made of high-density polyethylene material, which has excellent durability and crack resistance. It can withstand extreme temperature changes, subsurface stresses, and other environmental factors for long-term reliability and stability.

SDR17 PE gas pipe

Moderate pressure bearing capacity: The wall of SDR17 PE gas pipe is slightly thinner than that of SDR11 pipe, but still has sufficient pressure bearing capacity, suitable for medium pressure gas transmission system. It is commonly used for low and medium pressure gas transmission and supply, including domestic, commercial and industrial applications.

Flexibility and easy installation: Due to the lighter pipe wall and larger bending radius, SDR17 PE gas pipe has good flexibility and easy installation. It can adapt to different construction conditions and pipeline layout requirements, reducing installation time and labor costs.

Economical: Compared with pipes with higher SDR grades, SDR17 PE gas pipes usually have a lower cost. This makes it an economical and reliable choice for projects on a tight budget.

When selecting SDR11 or SDR17 PE gas pipe, a comprehensive evaluation is required based on specific application requirements, working pressure requirements and budgetary considerations. At the same time, ensure compliance with relevant regulations and standards to ensure the safety and reliability of the gas transmission system.

What is the difference between SDR11 and SDR17 PE Gas Pipe？

There are some differences between SDR11 and SDR17 PE gas pipes in the following aspects:

SDR11 and SDR17 represent two different standard dimension ratios (Standard Dimension Ratio). The tube wall thickness of SDR11 is relatively small, while the tube wall thickness of SDR17 is relatively large. Therefore, SDR11 PE gas pipe generally has a higher pressure rating and can withstand higher working pressure, while SDR17 PE gas pipe is suitable for medium pressure gas transmission.

SDR11 and SDR17 PE gas pipes have different pressure holding capacity due to different pipe wall thickness. SDR11 PE gas pipe has a higher pressure holding capacity and is suitable for gas transmission systems that require higher pressure, while SDR17 PE gas pipe is suitable for medium pressure applications.

The relatively thin wall of the SDR11 PE gas pipe gives it a smaller bending radius, so it is more suitable for use in piping arrangements that require a smaller bending radius. In contrast, the thicker pipe wall of SDR17 PE gas pipe may require a larger bend radius.

Due to their different pressure ratings, SDR11 and SDR17 PE gas pipes are suitable for different construction applications. SDR11 PE gas pipe is usually used in high pressure gas transmission system, while SDR17 PE gas pipe is suitable for medium pressure gas transmission and supply.

It is necessary to select the appropriate pipeline according to the specific gas transmission system requirements and design pressure to ensure safe and reliable gas transmission. When selecting and installing PE gas pipes, please follow relevant regulations, standards and recommendations, and consult professional engineers or cooperate with relevant industry organizations to obtain accurate design and construction guidance.
