Schedule 20 Steel Pipe
SCH 20 Steel Pipe
SCH 20 steel pipes are a reliable and economical choice for various industrial and commercial applications. Known for their lighter wall thickness compared to higher schedule pipes, SCH 20 pipes are ideal for systems where pressure and temperature requirements are moderate. These pipes conform to international standards, ensuring durability, performance, and compatibility with a wide range of applications.

Logistics
By Sea
By Air
By Land
Alloyxpert provides three transportation options: sea, land, and air. Sea transportation is the most commonly chosen method for most orders and is therefore regarded as the default transportation mode. Quotations are typically based on terms such as FOB, CFR, or CIF. For urgent requirements, we also offer air transportation, while land transportation is available for specific regional needs.
