Stainless steel flanges connect with pipe and fittings to form a piping system that delivers air, water, natural gas, oil, and steam in plumbing applications and food and dairy processing. Flanges provide easy access for cleaning, inspection, and modification. Flange types including blind, butt weld, lap joint, slip-on, socket weld, and threaded, are available in a variety of sizes and shapes. Stainless steel is durable, resists corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures.

A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.
HSS members can be circular, square, or rectangular sections, although other shapes such as elliptical are also available. HSS is only composed of structural steel per code.
HSS is sometimes mistakenly referenced as hollow structural steel. Rectangular and square HSS are also commonly called tube steel or box section. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimension and classed differently from HSS. (HSS dimensions are based on exterior dimensions of the profile; pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.
In the UK, or other countries which follow British construction or engineering terminology, the term HSS is not used. Rather, the three basic shapes are referenced as CHS, SHS, and RHS, being circular, square, and rectangular hollow sections. Typically, these designations will also relate to metric sizes, thus the dimensions and tolerances differ slightly from HSS.

Across several industries, a hydraulic cylinder tube is referred to as a Honed tube. One of the most important materials of manufacturing hydraulic cylinders are Honed Tubes. This type of tubing is ordinarily honed in the inside diameter of a Ready to Honed Tube. Which is why it is also known as honed ID tubing. Honing is an abrasive or a grinding machining process that delivers a precision surface on a metal workpiece for e.g. Hydraulic Tubes. During this process, an abrasive grinding stone or grinding wheel is scrubbed against a Pre Honed Tube along a hegemonized path. Honing is a process which is fundamentally used to enhance the geometric form of a surface.
