Frequently Asked Questions about Arc-Shaped Nano Microporous Insulation

Quick answers to common technical and commercial questions engineers and procurement teams ask about our Arc-Shaped Nano Microporous Insulation. For specifications not covered here, please contact our technical team.

Can you provide samples before I place an order?

Yes. Just share a few basics about your project – where the material will be used, the operating temperature, and the target thickness and size – and we will recommend the most suitable grade and specification for you to evaluate. The information is used purely for material selection. We treat every enquiry as confidential and never disclose your project details to any third party.

Can I still request samples if I am not allowed to disclose any project information?

Unfortunately not. Preparing each sample set takes dedicated effort from our team – cutting, packing, labelling and export documentation – and without knowing where the material will be applied we cannot judge whether our product actually suits your project. We fully respect your confidentiality requirements; even a general description of the application and its temperature range is enough for us to help you select the right material.

Are the samples free of charge, and how many pieces can I request?

Samples are free of charge. The standard sample set is two A4-size pieces of board, which is enough to evaluate handling, machinability and thermal behaviour. If you need larger pieces or a greater quantity for a trial lining, please explain the purpose and we will gladly support you. If you have never worked with microporous insulation before, we suggest starting with the standard set first: please confirm the material is likely to fit your project before requesting additional pieces, because every set we prepare takes real time and effort from our technicians.

Who pays the shipping cost for samples?

Freight is borne by the customer. Please provide your FedEx (or DHL/UPS) courier account number together with the full consignee details – contact name, company name, street address, postcode, telephone number and email – and we will arrange shipment on your account. If your company does not hold a courier account, tell us and we will quote the freight charge and arrange prepaid shipment for you.

How long does it take to prepare samples?

If the requested size is in stock, preparation normally takes 3 to 7 working days. If it is out of stock and the boards have to be produced to order, please allow 1 to 2 weeks. In both cases we work to the shortest possible lead time and notify you as soon as the shipment leaves our factory.

What is arc-shaped nano microporous insulation used for?

Arc-shaped nano microporous insulation panels are pre-formed rigid segments used for pipe insulation, particularly on large diameter lines where wrapping flat boards on site would lead to gaps, misalignments, and cold bridges. The arc geometry matches the curvature of standard pipe outer diameters, allowing the panels to sit flush against the pipe wall with consistent joint lines. Common applications include district heating main steam lines, petrochemical process pipes, power generation high-pressure piping, and marine engine room pipework. Arc panels are also used on tank and vessel heads where the curvature is concentric. The pre-formed geometry reduces installation time by up to 60 percent compared with cutting flat boards on site, and the tight factory tolerances deliver consistent insulating performance across the full pipe circumference.

What arc radius range is available?

Our standard arc-shaped nano microporous insulation range covers inner diameters from DN 50 to DN 1200. For each nominal pipe size the arc panels are pressed to the standard pipe outer diameter, including the standard insulation tolerance on pipe wall thickness. Common configurations include single-pane arc segments covering 90 or 180 degrees of circumference for fast pipe installation, and full 360 degree kits for vessel and tank heads. The standard thickness range is 20 to 100 millimeters; thinner panels are not typically supplied in arc form because the cost of forming exceeds the material savings. For diameters outside our standard list, our engineering team can produce tooling for custom radii on a project basis. Share your line list and we will confirm which standard configurations cover your pipes and which require custom tooling.

Can custom arc shapes be ordered?

Yes, we produce custom arc-shaped nano microporous insulation panels for projects that fall outside our standard radius and thickness range. The minimum order quantity for custom arc tooling is typically 20 cubic meters, which amortizes the tooling cost; for smaller quantities we recommend using our formed-shape service or wrapping flat boards on site. Once tooling is established, repeat orders carry only the per-piece cost and lead time. Typical lead time for custom tooling and first delivery is 6 to 8 weeks; repeat orders are 3 to 4 weeks from drawing confirmation. To place a custom arc order we need the inner diameter, thickness, segment angle, and quantity, plus any special requirements such as facings or facing combinations. We will return a CAD drawing for your approval before tooling release.

How is arc-shaped insulation installed in pipes and tanks?

Arc-shaped nano microporous insulation panels are installed using a simple alignment-and-secure process. The two halves of the arc (typically 180 degree each) are positioned around the pipe with the joint line vertical or at 45 degrees for clean visual finish. Stainless steel banding or high-temperature wire is wrapped around the panels at 200 to 300 millimeter centers to secure them against the pipe wall. For multi-layer arc insulation the inner layer is bonded with inorganic adhesive to the pipe and the outer layer is mechanically secured with through-bolts or welded pins. Joints between adjacent panels are filled with ceramic fiber strip and sealed with aluminum foil tape or PE tape as appropriate. The outer cladding is fitted last, providing weather and mechanical protection. Full installation drawings and pin schedules are available on request.

What is the typical thickness range for arc panels?

Our standard arc-shaped panels are produced in thicknesses from 20 to 100 millimeters. The most common project thicknesses are 30, 40, 50, 60, 80, and 100 millimeters, corresponding to typical pipe insulation duty at temperatures of 200 to 1000 degrees Celsius. Thinner panels below 20 millimeters are not normally supplied in pre-formed arc geometry because the geometry cannot be held to tight tolerance during forming; for thin insulation on small pipes we recommend flat boards with on-site cutting. Thicker panels above 100 millimeters are produced as multi-layer assemblies with staggered joints to minimize thermal bridging through seams. For heat-loss calculations against specific duty profiles, our engineering team can run ISO 12241 or ASTM C680 calculations on receipt of your pipe data and recommend the optimal thickness.

How does arc insulation compare to cutting flat boards on site?

Pre-formed arc insulation offers three advantages over cutting flat boards on site. First, the geometry is consistent, which means consistent insulating performance across the full pipe circumference with no cold bridges at poorly-fitting joints. Second, installation time is reduced by 40 to 60 percent because the panels are simply positioned and banded rather than measured, cut, and trimmed on site. Third, material waste is reduced because we optimize the blank size during pressing; on-site cutting typically generates 10 to 15 percent scrap. The trade-off is a unit cost premium of typically 15 to 25 percent over flat boards of equivalent thermal performance. For high-spec projects where thermal performance, install quality, and reduced labor cost matter, the arc premium is recovered within the first few cycles of installation.

Why Engineers Choose Arc-Shaped Microporous Insulation

Arc-shaped nano microporous insulation is the factory-pre-formed variant of our microporous insulation panel range — single-curve segments cut to your pipe diameter in 90° or 180° arcs for pipe diameters DN 50 to DN 1200.

Each arc is cut from the same fumed silica microporous board stock, maintaining the 0.020 W/(m·K) thermal performance of microporous thermal insulation installations while eliminating on-site cutting waste.

For thermal-insulation contractors installing hundreds of metres of lined pipework, pre-formed arcs halve the on-site labour cost of a comparable high temperature insulation panel installation built from flat board.
