# Category: Pipe fittings, fittings - [As if we hadn’t got a single “pipe-farthing”?!](https://menet-trend.hu/en/nonox-world/as-if-we-hadnt-got-a-single-pipe-farthing.md) — NONOX stainless and acid-resistant pipe fittings hold together the systems that run across wide temperature ranges and in corrosive media. From the base grades 1.4301 to 1.4404, through ball valves, elbows, press bends, reducers, sockets, unions and flanges, to Kamlok quick couplings and the thread types that join them all. - [Wastewater never stops](https://menet-trend.hu/en/nonox-world/wastewater-never-stops.md) — A conversation with the technical director of a partner that designs and builds industrial and municipal wastewater treatment systems: why carbon steel is banned around food, what OKS-250 paste solved, and why the non-return valve is all but forbidden in industry. - [Pipe clamp](https://menet-trend.hu/en/nonox-world/pipe-clamp.md) — A pipe clamp is a pipe clamp – or is it? Galvanised clamps are fine for heating, gas and water pipes, but food, chemical and energy plants demand stainless. NONOX A2 clamps are made from 1,8-1,9 mm stainless steel with stiffening ribs and bear up to 150 kg – plain or rubber-lined, in many sizes. - [Pipe fittings, fittings](https://menet-trend.hu/en/nonox-world/pipe-fittings-fittings.md) — How does water flow from the tap? A pipeline network criss-crosses our walls and the depths of the earth, and its elements are the pipe fittings. Elbows, T pieces, unions, flanges, quick couplings and ball valves, in cast iron, A2 stainless or A4 acid-resistant steel. --- HTML:
