The SAE J356 specification covers electric resistance welded, flash-controlled, normalized, single-wall, and low-carbon steel pressure tubes.
These SAE J356 Hydraulic Tubing are specifically designed for applications involving pressure lines and situations where tubing quality is crucial for processes such as bending, double flaring, beading, shaping, and brazing. It’s important to note that due to the potential leak route introduced by the inner diameter (ID) weld bead, this material is not recommended for single flare applications.
SAE J356 Type-A, a subset of this specification, refers to smaller diameter, light-wall tubing, typically with an outer diameter (OD) of 5/8″ or less and 18 gauge or thinner. Type-A tubing is annealed “in line,” in contrast to the standard SAE J356 where normalization is conducted separately. The performance criteria for Type-A tubes align with those of J356 tubes, although the chemical composition ranges for carbon and manganese are more comprehensive. Type-A tubes are often produced in coil form, although they can be cut and straightened using secondary processes.
SA179 Tubes is a prominent supplier, exporter, and stockist of SAE J356 Hydraulic Tubing, based in Mumbai, India. We produce these SAE J356 Hydraulic Tubes using high-quality raw materials and the latest technology, adhering to global quality standards.
To ensure the quality and reliability of SAE J356 Hydraulic Tubing, these tubes undergo thorough evaluation following SAE J1677 standards. The tests include the Flattening Test, Flaring Test, Reverse Flattening Test, Expansion Test, Hardness Test, Tensile Test, Pressure Proof Test, and a Nondestructive Electronic Test.
This meticulous testing ensures that SAE J356 Hydraulic Tubing meets the stringent requirements of hydraulic and pressure applications, guaranteeing their performance and safety in demanding conditions.
