Solid (regarding the material used in equipment manufacturing)?

Based on the context, I think the meaning here is: to make it firm or stable.

Solid? Is the device covered with metal or is it solid (metal)? ) It depends on the design pressure. I don’t know whether it’s solid metal or some other solid material. I guess it’s solid metal. If the pressure requirements are low, a metal coating on another material can be used; if the pressure requirements are high, a solid metal material is employed.

SOLID, CLAD OR LINED CONSTRUCTION A variety of process equipment has been fabricated from solid titanium, titanium-clad steel, and with titanium linings. The choice between one construction method and another depends on several factors, including the operating environment, manufacturing feasibility, and cost. Consulting with experienced titanium fabricators can help in making the right selection. Solid titanium: pure titanium; Titanium-clad steel: titanium/steel composite plates; Titanium linings: coatings made of titanium. Recommendation: Solid refers to materials that are pure, homogeneous, and consisting of a single element

It seems to mean “homogeneous,” similar to the meaning of homogenous. “Clad” refers to layers or multi-layer structures, but I’m not entirely sure about the exact meaning. Just offering my opinion. This post was last edited by RainWolf on 2009-2-16 at 12:27.]

Clad means it has a metal coating or alloy. If it refers to an alloy, then it means “alloyed or homogeneous”.

The equipment is clad or solid depending on the design pressure. Depending on the design pressure, the equipment can have a composite lining or be solid. Generally, for equipment operating in corrosive environments, high-quality materials are required. However, in the case of high-pressure equipment, the wall thickness must be greater, which increases the cost of the equipment. Using a solid structure results in high costs; in such situations, composite panels can be an alternative – a layer of high-quality material is applied over a carbon steel core, thereby providing both high strength and corrosion resistance while keeping the cost of the equipment low.

It should refer to the physical entity (the base layer of the composite panel)

The equipment is clad or solid depending on the design pressure. Whether the equipment is made of composite material or a single material depends on the design pressure. Reason 7 explains this, but translating it as \"solid\" is incorrect. Reason 4’s understanding is correct; \"solid\" should be translated as \"single material,\" with the original meaning being \"pure.\" In contrast to solid, \"clad\" refers to composite material, including various types of composite panels

It should be either a solid object, or one with a hole in it; perhaps “integral” would be a more appropriate term. Those who have seen high-pressure ethylene polymerization reactors will think that the reactor is simply a piece of steel with a hole cut in it.

Both clad and solid represent different construction methods for pressure vessels; these various structures correspond to multi-layer rolling and solid forging respectively. During a technical exchange some time ago, a manufacturer mentioned this, and at that time I didn’t know the corresponding English terms. I just remembered them now. Since I’m not an engineer, I had to look it up to find out the answers. You can refer to the following link: http://www.chinabaike.com/article/baike/1000/2008/200805111455659.html. Here’s an excerpt from that article: Pressure vessels are mainly cylindrical in shape, with a few being spherical or of other shapes. Cylindrical pressure vessels are typically composed of components such as the cylinder body, end caps, nozzles, and flanges. Its cylinder is generally formed by rolling a single layer of steel plate into a cylindrical shape and then welding it together. The higher the operating pressure of a pressure vessel, the thicker its wall should be. For thick-walled pressure vessels with smaller diameters, a thick-walled cylinder forged as a single piece is often used. The wall thickness of pressure vessels with large diameters can reach 100–400 millimeters. Pressure vessels come in various structural forms, such as multi-layer type, wound-plate type, grooved-wound-band type, heat-shrink type, thick-plate rolled-welded type, and forged-welded type. Multi-layer pressure vessels began to be used in industry as early as the 1930s. Pressure vessels of this structure are welded together from several multi-layer tube sections. Each tube section consists of an inner tube and laminates wrapped around it. The thickness of the inner cylinder is generally 12 to 25 millimeters, while the thickness of the outer layer plates is generally 6 to 12 millimeters. After the inner cylinder is manufactured, the laminates are wrapped concentrically around the outside of the inner cylinder, with steel wires used to secure the laminates to the inner cylinder. Then, the longitudinal welds of the laminates are welded; the wrapping force together with the contraction force resulting from welding these longitudinal welds ensures that the laminates adhere tightly to the inner cylinder, thereby applying a pre-compressive stress to the inner cylinder. After the first layer of laminates is wrapped and welded, each subsequent layer of laminates is wrapped and welded in the same manner until the desired thickness of the cylinder is achieved. The advantage of this structure is that the manufacturing equipment is relatively simple, and there is great flexibility in material selection; an appropriate inner cylinder material can be chosen based on the corrosivity of the medium, while the layer plates are typically made of steel used in ordinary pressure vessels. With this structure, even if a crack appears in one layer of steel plate, the crack can only spread within that layer and will not extend to other layers. Vent holes are provided in the plates of each cylinder section, which can be used to monitor for leaks in the inner cylinder in order to prevent accidents.

http://www.caci.org.cn/3asmeforum/2fy/TRAN2002-11.htm It seems that the approach may vary slightly depending on the context. But for the echo problem, I think my conclusion above is correct

More original text: The currently preferred materials of construction used for most of the equipment in this process is zirconium 702. The equipment is either clad or solid depending on the design pressure. In the equipment table, under the \"construction material\" column, it is listed as \"cladding: zirconium 702\", but \"solid\" has never been mentioned. I think \"solid\" and \"cladding\" here also refer to the manufacturing materials. A direct translation: Whether the device is lined or solid depends on its design pressure. It feels a bit awkward; it should be handled properly: whether the equipment is made of composite material or a single material depends on its design pressure.

Clad is a composite material; generally, it consists of two different materials to form a certain thickness. Solid is made up of the same material to form a certain thickness.

solid: pure, referring to a single material here
