ASTM A333 Gr6 Double Threaded Nipples Delivered to Singapore

Low-temperature piping projects in Singapore often require compact threaded connectors that maintain toughness under cold operating conditions. Haihao Group has finished fabrication and shipment of ASTM A333 Gr6 double threaded nipples for a local industrial piping system. This batch of seamless fittings follows ASME B36.10M dimensional rules, with full marking and surface treatment carried out according to the client’s technical requirements.

ASTM A333 Gr6 double threaded nipple, SCH80 galvanized seamless TBE pipe nipple with NACE green and white color band for Singapore piping project

Product Specification Table

The ASTM A333 Gr6 double threaded nipple is sized at 0.75 inch, 4-inch length with SCH80 wall thickness. As a low-temperature carbon steel fitting, it is made from seamless pipe stock, machined with threads on both ends (TBE). The fittings are galvanized for extra rust resistance, and marked with NACE color bands in green and white, matching RAL 6021 and RAL 9010 color codes. The color marking helps site engineers quickly identify material grade and service specification during installation.

Many end users in Southeast Asia select ASTM A333 Gr6 double threaded nipple for cold service pipelines, because ASTM A333 Grade 6 carbon steel retains reliable impact toughness at sub-zero temperature. The seamless base eliminates weld seam risks, while SCH80 heavy wall offers stable pressure capacity. Haihao Group controls thread machining precision strictly to ensure tight, leak-free assembly with matching threaded fittings on site.

Before packing and dispatch, each ASTM A333 Gr6 double threaded nipple went through dimensional inspection and thread check. Our team applied the specified NACE colour band marking after galvanizing treatment. We can adjust marking schemes, coating types and thread forms to meet different regional and project specifications for threaded pipe nipples.

If you are sourcing low-temperature seamless threaded nipples for oil, gas or process piping, send your specifications to our engineering team. Haihao Group can produce custom threaded pipe nipples, provide material test certificates and arrange export packaging for Singapore and other Southeast Asian markets.
