Square Hollow Carbon Steel Tube | Custom Length, ASTM Specification and Oil Pipe Requirements
Square hollow carbon steel tube is listed with 0.4–16mm wall or required thickness. The body records 6m, 6.4m and 12m lengths, alongside a 6–12m customized length description. There are no actual dimensional selectors.
The outside side dimensions and steel grade designation are absent. Define width, height, wall and finished length together, then request the applicable ASTM hollow-section specification. Non-alloy carbon steel is a material category rather than evidence of a particular grade or strength.
For cutting or bending, provide the drawing and finished dimensional limits. The source also mentions oil, hydraulic, boiler and other pipe uses, but those application names do not establish pressure suitability or API certification for this square section. Material documentation and service-specific requirements are needed before judging a fluid or structural application.
