Incoloy 825 Perforated Sheets Supplier

Kalpataru Piping is a trusted supplier and exporter of Incoloy 825 perforated sheets to cater to industries all over the world with certified material and custom perforation solutions. Our UNS N08825 perforated sheet is made of high-quality Incoloy 825 bar and plate stock, and offers the exceptional corrosion resistance that this nickel-iron-chromium product is known for. Each perforated sheet is individually tested to ASTM B424 / ASME SB424 prior to dispatch, as part of our all-encompassing Incoloy perforated sheet range.

Incoloy 825 perforated sheets are a combination of the excellent resistance properties of the alloy against reducing and oxidising acid and the flexibility of perforated form. The nickel-iron-chromium base alloy combined with the added elements of molybdenum, copper, and titanium provides a high level of resistance to sulfuric and phosphoric acids, chloride-induced stress-corrosion cracking (SCC), and crevice corrosion, which other stainless steel perforated sheet can’t provide in harsh process environments.

FAQ’s About ASTM A106 Grade B Pipes

What is ASTM A106 Grade B pipe?

ASTM A106/A106M Grade B is a seamless carbon steel pipe specification intended for high-temperature service. The exact project suitability depends on the governing piping code, design conditions and purchase specification.

What is the difference between ASTM A106 Grade B and ASTM A53 Grade B?

ASTM A106 Grade B is a seamless high-temperature-service pipe specification. ASTM A53 Grade B covers welded and seamless pipe for mechanical and pressure applications and ordinary steam, water, gas and air service. Select the specification required by the project and design code.

What sizes does Kalpataru supply?

The current brief lists a Kalpataru supply range of 1/2 to 36 in NPS and Schedule 10 to XXS, subject to size and availability. ASTM A106/A106M itself has a wider standard scope.

What is the maximum temperature of ASTM A106 Grade B pipe?

Do not use one universal maximum temperature from the ASTM material specification. Allowable service depends on the design code, pressure, wall thickness, allowable stress and project conditions.

Is ASTM A106 Grade B seamless or welded?

ASTM A106/A106M is a seamless carbon steel pipe specification. Do not describe ERW, LSAW or other welded pipe as ASTM A106 product construction.

What tests are required for ASTM A106 Grade B pipe?

The specification includes mechanical testing and bend/flattening testing as applicable, together with hydrostatic and/or nondestructive electric testing requirements. The exact inspection package should match the current ASTM edition and purchase order.

What documents can be supplied?

Orders can be supplied with EN 10204 3.1 MTC and, where applicable and agreed, IBR documentation, third-party inspection and project-specific test reports.

How is ASTM A106 Grade B pipe priced?

Price depends on NPS, schedule or wall thickness, length, quantity, origin/mill, testing/certification, coating/end preparation and delivery destination. Send the full requirement for a size-wise quotation.
