Introduction
Kalpataru Piping is one of the leading Manufacturer, Supplier and Exporter of Super Duplex Steel UNS S32550 Plates & Super Duplex Steel UNS S32550 Sheets that are using high quality raw materials. Super Duplex UNS S32550 Plates & Super Duplex UNS S32550 Sheets plates contains generally elevated amounts of chromium (somewhere around 18% and 28%) and low to direct measures of nickel (somewhere around 1.5% and 8%). The high erosion resistance and phenomenal mechanical properties of duplex stainless steels can be ascribed to their substance organization and adjusted (duplex) microstructure of roughly equivalent volume rates of ferrite and austenite. Duplex Steel UNS S32550 Plates Excellent corrosion resistance in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids, High resistance to abrasion, erosion and cavitation erosion, Tested to the highest degree using tests designed to guarantee that the trade-marked product possesses high integrity, a correct phase balance and the absence of sigma and other deleterious phases.

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.
