Brief Introduction
Our hot rolled seamless carbon steel pipes are manufactured through one-time hot piercing and rolling forming without any welding seam. Compared with welded pipes, they eliminate hidden risks such as welding cracks and air holes, featuring uniform wall thickness, stable mechanical properties and excellent pressure resistance.Comply with API 5L, ASTM A53 and other international pipeline standards, widely applied in crude oil gathering, natural gas long-distance transportation, wellhead connection and buried pipeline projects. Every pipe undergoes 100% hydrostatic test and non-destructive flaw detection before delivery, with complete test certificates to support global engineering bidding and customs clearance. Custom size, pipe end processing and anti-corrosion coating services are available to meet diverse project demands.

Core Advantages & Selling Points
1.Integral seamless forming, safe for high-pressure transportationOne-piece hot rolling molding without welding joints, no weak stress points. Burst resistance is 15%-20% higher than welded pipes, completely avoid leakage and pipe burst during long-term oil & gas delivery.
2.Refined metal grain, stable performance under extreme temperatureHigh-temperature hot rolling optimizes internal metal structure with uniform wall thickness and low ovality. Outstanding low-temperature impact toughness, no brittle fracture in cold oilfield areas, and stable service at high-temperature wellheads.
3.Low-impurity raw material, good medium corrosion resistanceAdopt low S&P qualified steel billets via spectral inspection. Effectively resist corrosion from sulfide, formation water and weak acid mixed in crude oil and natural gas, extending pipeline service life.
4.Full strict inspection system, zero internal defectsComplete production inspection flow: raw material chemical test → dimensional inspection → straightening → 100% UT/MT non-destructive testing → independent hydrostatic pressure test → finished product recheck. Each batch has complete records for full traceability.
5.Full customization service to match different construction needsSupport custom OD, wall thickness, fixed length, welding bevel, thread processing and multi-layer anti-corrosion coating. Laser marking of heat number, grade, standard and specifications on each pipe for easy identification.
6.Cost-effective mass production solutionHigh production efficiency for large-diameter and heavy-wall pipes that cold-drawn tubes cannot produce. Easy to weld, cut and bend on site, greatly reducing secondary processing costs for EPC projects.
7.Export-grade packaging for long ocean shipmentPipe ends covered by plastic caps to prevent scratch and rust; bundled by high-strength steel strips and wrapped with waterproof woven cloth, resisting collision and moisture during sea transportation.
