An Incoloy 800 / 800H / 800HT lateral is a fitting with a 45° branch, made from Incoloy 800 / 800H / 800HT to ASTM B366 WPNIC. Laterals bring in a branch at 45°, reducing turbulence and pressure drop compared to a tee. Common in drainage, slurry and process lines.

FOB / CIF · Nhava Sheva (JNPT), MumbaiIncoloy 800 / 800H / 800HT Lateral — questions buyers ask
When is a lateral better than a tee?
Where lower turbulence matters — slurries, solids and gravity drainage.
Which standard covers Incoloy 800 / 800H / 800HT laterals?
The material is ASTM B366 WPNIC; dimensions follow MSS SP-43 / manufacturer standard. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Incoloy 800 / 800H / 800HT lateral?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
