Everyone knows the flange route: weld a flange onto the pipe end, bring the two flanges together underground, run up the bolts. The grooved coupling takes a different process route

Backfill and slurry lines may carry tailings, paste, water, or other process materials containing solid particles. The operating conditions vary by project, so equipment should be

Choosing a piping system for a mine is never a one-size-fits-all decision. An underground coal mine and an open-pit mine may both need to move water, slurry, and hydraulic fluid —

Victaulic Style 995N is a mechanical coupling designed for joining plain-end high-density polyethylene (HDPE) pipes. It provides a mechanical connection without requiring conventio

This guide summarizes the main types of pipeline systems used in underground and open-pit mines worldwide, and compares the six connection methods most commonly used to join them —

Mine piping is not one duty. Three service families cover most of the underground network, and each one punishes a joint differently.

“DN100” is not a physical measurement. Depending on applicable standards, DN100 may correspond to 108 mm, 110 mm or 114.3 mm outside diameter (OD). A gap up to 6.3 mm cannot be com

Choosing the right joining method directly determines installation efficiency, system reliability and longterm maintenance cost.

It looked simple enough at first. The client listed the pipe sizes and lengths, and asked for a quotation. But attached to the enquiry was a full specification: the pipe was to com

The remaining question is stiffness. Should that joint be rigid or flexible?

Geological subsidence, as well as thermal expansion and contraction of the pipe, can cause pipeline deflection and misalignment,

After years of on-site installation, commissioning and maintenance at coal mine roadways, filling working faces and hydraulic support sites, the picture is consistent. Static overpressure is rarely the cause of a pipeline failure. What kills underground pipework is the gap between what the spec sheet says and what the roadway does to it.
