Schedule 40 galvanized steel pipe

Schedule 40 galvanized steel pipe

1. What is Schedule 40 galvanized steel pipe?

Schedule 40 galvanized steel pipe is a common type of carbon steel pipe, which is treated with hot-dip galvanizing or cold galvanizing on the surface of ordinary carbon steel pipes. Form a uniform zinc layer, thereby enhancing corrosion resistance and service life. Among them, Schedule 40 (SCH 40) refers to the wall thickness grade of the pipeline. Among numerous wall thickness grades, Schedule 40 is the most common specification and is widely used in water supply, gas, building structures and industrial transportation systems.

2.Schedule 40 galvanized steel pipe dimensions and specifications

SCH 40 complies with ANSI B36.10 standard and it has multiple wall thickness grades: Sch10, Sch20, Sch30, Sch40, Sch60, Sch80, Sch100, Sch120, Sch140 and Sch160, Schedule 40 galvanized steel pipe size details are as follows:

Specification (inches)	Outer diameter (in/mm)	Wall thickness (in/mm)
1/2″	0.840″ (21.3 mm)	0.109″ (2.77 mm)
1″	1.315″ (33.4 mm)	0.133″ (3.38 mm)
2″	2.375″ (60.3 mm)	0.154″ (3.91 mm)

Common execution standards for Schedule 40 galvanized steel pipes include: ASTM A500/A501, EN10219/10210, JIS, ASTM A53, BS 1387, EN 10255, etc.

Compared with Schedule 20 and Schedule 80 galvanized steel pipes, Schedule 40 achieves a better balance among pressure resistance, economy and applicability - its wall thickness is thicker and stronger (capable of withstanding higher pressure) than Schedule 20. However, it is lighter and more cost-effective than Schedule 80, and is particularly suitable for pipeline applications in medium-pressure scenarios where both cost and installation difficulty need to be considered while ensuring reliability.

3.Schedule 40 Advantages of Galvanized Steel Pipes

Strong corrosion resistance: The galvanized coating can effectively prevent the steel pipe from direct contact with air and moisture, thus prolonging its service life.
High cost performance: Compared with stainless steel pipes, it is cheaper, but still has good anti-rust and anti-corrosion capabilities.
Reliable strength: The wall thickness of Schedule 40 pipes meets the requirements of most medium and low pressure systems.
Wide application range: It is widely used in both civilian and industrial scenarios.

4. Common application fields

The application fields of Schedule 40 galvanized steel pipes are very extensive, mainly including:

Water treatment: It is mostly used for urban water supply and internal pipe networks of buildings, and can also be used for wastewater treatment.
Gas pipeline: Low-pressure gas transmission.
Fire protection system: Fire sprinkler pipes and related supports.
Architecture and Structure: Commonly used in structural applications; Such as steel structure supports, scaffolding, guardrails, and railings.
Agriculture and machinery: It can be used in irrigation systems, greenhouse frames, mechanical supports, fences, etc.
