Guide Helps Avoid Conduit Damage

US-based Plastics Pipe Institute (PPI) says that a new guide will help installers to calculate safe pulling loads – and avoid damaging HDPE conduit. The technical note, TN-63, provides the equations needed to calculate the Safe Pull Strength (SPS) for HDPE conduit, plus tables of pre-calculated SP......

Understanding the AWWA C900-16 Standard for PVC Pressure Pipe

AWWA published its new C900 standard in August 2016. C900-16 now includes all of the AWWA PVC pipe sizes, rendering the AWWA C905 standard obsolete. The Uni-Bell PVC Pipe Association has prepared a guide to the new standard that explains the changes from the previous standards and provides other per......

Precautions for Operation of Plastic Pipe Production Equipment

Here we prepared to introduce the key points of pipe extrusion are as follows:

Process Flow of PE Pipe Equipment

The process flow of HDPE pipe is basically the same as that of LDPE pipe, except that HDPE pipe is hard pipe, so it is fixed length sawing, while LDPE is semi-hard pipe, which can be coiled. Generally, it is coiled into a roll of 200-300m. Now take LDPE as an example to introduce its process flow:

Selection of Raw Materials for PVC Pipe Production Equipment

Polyvinyl chloride (PVC) plastic is a multi-component plastic. Different additives can be added according to different uses, and the products also show different physical properties. PVC pipe is divided into soft and hard. UPVC pipe is made by mixing PVC resin with stabilizer, lubricant and other ad......

Type of Haul-Off

In the process of extruding pipe, the pipe diameter and wall thickness can generally be adjusted by changing the traction speed. Therefore, in production, the traction of pipe is required to be uniform and stable, and the traction speed adjustment is convenient and sensitive, so as to ensure the uni......
