Technical specifications for anchor pins
Thread Content
Anchoring bolts for refinery heating furnaces are generally manufactured by specialized manufacturers; I wonder what the manufacturing standards are? I heard there are two standards: \"Technical Requirements for Anchor Pins of Single-Layer Linings in Petrochemical Tubular Furnaces\" and \"Technical Requirements for Anchor Pins of Double-Layer Linings in Petrochemical Tubular Furnaces\". Does anyone know about these? If there is an electronic version, please share it so we can all learn together!*
Insulation nails for heating furnaces are made of carbon steel, stainless steel, or a combination of carbon steel and stainless steel. It’s just made by bending round steel or folding 2mm thick steel plates – what technical difficulty could there be? We used V-shaped insulation nails in the past, and we’ve been using them for many years; is there any need to make such a big deal out of them? It is necessary to focus on both technology and the economy. I’m not well-informed. This post was last edited by eddy-8280103 on 2009-2-26 at 16:54.]
Among the insulation studs used in refineries, I am aware of V-shaped, Y-shaped, and Ω-shaped ones. I heard for the first time that there are also insulation studs made by folding steel plates with a thickness of 6–8 mm. I wonder what the specific applications or conditions for these different types of insulation studs are. For example, on furnace walls – what kind of insulation studs are used when spraying fibers, and what kind are used when using cast materials? What about in the case of a furnace roof?
Insulation nails made by folding steel plates of 6–8 mm in thickness; the steel is stainless steel. Such insulation nails are used in lined equipment such as the auxiliary combustion chambers of catalytic units and catalyst storage tanks, and they are also Y-shaped in design
Most of the equipment that requires lining is secured using anchor bolts. For some of our catalytic cracking equipment, the anchor bolts are welded in place first, and then the lining is installed, so that the lining can be firmly fixed to the equipment! !
If fibers are used, use anchor pins. If it is a casting material, anchor bricks are required ； The anchoring bricks are suspended from the steel structure using angle iron or anchoring clamps.
\"Technical Requirements for Anchor Pins of Single-Layer Linings in Petrochemical Tubular Furnaces\" and \"Technical Requirements for Anchor Pins of Double-Layer Linings in Petrochemical Tubular Furnaces\" are standards set by Lopeik LPEC; it is quite difficult for people who are not part of the company to obtain them. . .
Generally, anchor bolts are used at low temperatures, while anchor bricks should be employed at high temperatures above 1100 degrees.
In my opinion, chemical processing equipment has high requirements, and strict standards are certainly necessary to guide and regulate its design. As for ordinary heating furnaces, Y-shaped pins made of standard heat-resistant steel plates should be sufficient. However, for equipment with high demands, heat dissipation in this area also needs to be taken into consideration; that’s why elements such as bricks for anchoring are used
