Product introduction

Product Overview

219mm ERW Carbon Steel Pipe is medium-caliber high-frequency electric resistance welded straight seam steel pipe, also known as DN200 standard pipeline pipe, produced via advanced high-frequency ERW forming & welding technology. Uniform wall thickness, smooth inner & outer pipe wall, compact weld structure, zero internal welding burr after inner scarving, stable pressure resistance and outstanding airtight performance. Widely applied for municipal water/gas trunk pipeline, industrial fluid delivery, building structure piling, fire-fighting main pipe, sewage drainage and petrochemical medium conveying, one of the most mainstream medium-diameter ERW pipe specifications for domestic and overseas engineering procurement. All products strictly comply with global mainstream pipeline standards, full-process factory inspection including hydrostatic test & weld NDT flaw detection, available for hot-dip galvanized, 3PE/2PE anti-corrosion, internal epoxy coating customized processing to adapt buried, exposed and underground complex laying environments.

Five Core Product Advantages

High-Integrity Weld Performance, Anti-Leakage

Automated high-frequency solid-state welding, weld metallurgical fusion with base steel as a whole, no crack, inclusion or pinhole defect. Every single pipe undergoes 100% online hydrostatic pressure test + weld ultrasonic non-destructive inspection, completely eliminate pipeline leakage risk for long-term gas/water delivery engineering.

Smooth Inner Wall, Low Flow Resistance

Full automatic internal scarving to clear welding burr thoroughly, smooth bore effectively reduce fluid friction loss, avoid impurity sediment clogging inside pipeline, improve delivery efficiency and cut long-term pump energy consumption, perfect for large-flow trunk pipe network.

Standard Universal Size, Full Fitting Compatibility

219mm (DN200) is international general medium-caliber standard dimension, fully matched with standard elbow, tee, flange, valve and pipe fittings from global brands, convenient on-site welding & flange connection, shorten construction period and reduce accessory matching cost.

Excellent Mechanical Property for Complex Environment

Q235B/Q355B/L245 raw material with stable tensile & yield index, outstanding compression & bending resistance, resistant to external soil squeeze and construction impact, suitable for buried underground, overhead rack laying, swamp & mountain complex terrain pipeline engineering.

Superior Cost Performance vs Seamless Pipe

Compared with seamless steel pipe, ERW 219mm pipe owns lower procurement cost while fully meeting medium-pressure pipeline design standard, stable finished yield rate and low post-operation maintenance expense, preferred bulk purchase option for municipal, industrial and overseas EPC projects.
