Here are some lubricants that typically work well for lubricating pipe processing machine:

Food-grade grease:

Greases made for incidental food contact, such as H1 food-grade grease, are safe for lubricating parts on machinery that processes food pipes. They provide good water resistance.

NLGI grade 2 lithium grease:

Lithium grease is tolerant of water washout and resists softening at high temperatures. The NLGI grade 2 variety has a smooth texture suitable for rolling and sliding components.

Synthetic oil:

Synthetic oils like polyalkylene glycol (PAG) oil are non-toxic and quite viscous, making them good lubricants for gears, chains, and other parts with high loads. They withstand wide temperature ranges.

HT 250 grease:

A semi-fluid, extreme pressure grease that adheres well to parts. It is capable of handling heavy loads and damp or wet environments commonly found in pipe production facilities.

Barium complex grease:

This thick, tacky grease contains solid lubricants that provide protection in boundary and mixed lubrication conditions. It is corrosion inhibiting and suitable for slow to medium speed applications.

I’d recommend verifying the machinery manufacturer’s recommendations as well, as they will have specific application and temperature range details for the machine models. Proper lubrication is important for optimal performance and part life.
