HDPE Silicon Core PipeSpecification and Model Issues: Generally, before procurement, there is a detailed procurement list that includes specifications, model, weight, material, color, and other detailed information of the required items.

If there is no detailed procurement description, you at least need to determine the specification of the required silicon core pipe. The common method to specify the HDPE silicon core pipe's specification and model is by using the inner diameter and outer diameter. For example, a silicon core pipe with an outer diameter of 40 and an inner diameter of 33 would be represented as 40/33 or 33/40. Another method uses the outer diameter and wall thickness. For instance, a silicon core pipe with an outer diameter of 40 and a wall thickness of 3.5 is represented as 40*3.5, which is essentially the same as the 40/33 silicon core pipe, as (outer diameter - inner diameter)/2 equals the theoretical wall thickness. The unit here is mm. This means that to scientifically determine the specification of a silicon core pipe, at least two of the following data are required: inner diameter, outer diameter, and wall thickness. Some might say they need a 40 silicon core pipe, and others would understand they mean the 40/33 type, as the 40/33 silicon core pipe is commonly used and people might refer to it that way. However, if you say you need a 50 silicon core pipe, would others know whether you need the 50/41 or the 50/60 type?
