Hastelloy Buttweld Fittings Manufacturer and Supplier in India
Home > Hastelloy Products > Hastelloy Buttweld Fittings
Hastelloy Buttweld Fittings are high-performance piping parts that are used to join, redirect, reduce or terminate pipelines in high-temperature and highly corrosive environments. These are fabricated by forming and machining Hastelloy alloy pipe or plate, then precisely beveling, heat treating and dimension checking to ASME B16.9 standards. These buttweld fittings are commonly made up of nickel, molybdenum, chromium and other materials that help to provide high resistance and corrosion resistance in harsh chemical environments. They are made in many different grades according to industry requirements; some of the most common, which are used, are known as Hastelloy C22, C276, C2000, B2 and B3 and in different configurations such as elbows, tees, reducers, caps, stub ends and crosses. Kalpataru Piping is a renowned manufacturer and exporter of Hastelloy Buttweld Fittings in India, offering the best products at low prices.

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.
