The ASTM A733 standard applies to carbon steel and stainless steel nipples of connections used for pressure pipes. It stipulates material demand, dimensional tolerance, mechanic properties, and test demand, and it is especially suitable for environments that need high strength and anti-corrosion performance.

1. Product Name1-inch × Schedule 40 seamless nipple
ASTM A733
Nominal Pipe Size (NPS): 1-inch nipple
Wall Thickness: Schedule 40 and conforms to ME B36.10/B36.19 standard.
Length: 1/2 to 8 inches, and customized size.
Thread Type: male thread on both ends or one male thread and one unthreaded end.
304/304L or 316/316L stainless steel.
304/304L stainless steel nipple has excellent corrosion resistance performance, suitable for most neutral or weakly acidic environments.
The 316/316L stainless steel nipple has molybdenum to enhance its anti-corrosion properties, making it suitable for harsh chemical or marine environments.
Seamless pipe nipples use the seamless pipe as original materials, precision cutting, and mechanic processing.
Seamless steel pipe ensures uniform mechanical properties and higher pressure resistance.
Precision machined threads, conforming to ANSI/ME B1.20.1 (NPT) or ISO 7/1 (BSPT) standards, ensure a tight connection with no risk of leakage.
Smooth surface or passivation treatment that enhances corrosion resistance and durability.
