LSAW Steel Pipe

LSAW steel pipes which are Large-diameter straight seam double-sided submerged arc welded steel pipes, are widely used in oil and gas pipelines, sour service pipelines and submarine pipelines, refining and chemical pipelines, high-end structures and coating steel pipelines and other market fields.
In order to meet the needs of customers and ensure the quality of products, we got ISO quality, safety and environmental management system, and has obtained the A/B pressure pipeline production license and many world-class product certifications such as API 5L,CE PED&CPR etc.
our LSAW steel pipe has been approved by most Chinese large domestic enterprises such as Petro China, Sinopec, CNooc, China Aviation Oil, China Gas, China Communications Group, China State Construction, China National Chemical Corporation and XinAo Gas, HSPC has obtained access qualifications for oil and gas company owners and EPCs from multiple countries and regions, such as ADNOC, KOC, Sonatrach, GASCO, PTTEP, Petrofac, TechnipFMC, Technimont, Larsen&Toubro, Samsung Egineering etc.

LSAW Carbon Pipes Quality Control

It is our responsibility and mission to provide customers with stable quality, safe and reliable products. Our factory has a national CNAS laboratory, with perfect testing methods, and implements traceability quality inspection from raw material procurement to manufacturing and finished products leaving the factory to ensure that products meet national standards and meet customer needs.
✔ Raw material inspection
✔ Process inspection
✔ Finished products inspection
✔ Final inspection and document filing
lsaw pipe test
We fully implement effective product quality control, and runs the nine "100% controls" through every part of the production inspection process.
● 100% recheck rate of physical and chemical analysis of raw materials
● 100% ultrasonic flaw detection rate of all welding seam
● 100% detection rate of steel pipe size
● 100% ultrasonic flaw detection rate of steel plate
● 100% x-ray inspection of all welding seam
● 100% detection rate of steel pipe appearance quality
● 100% hydrostatic test rate of steel pipe
● 100% physical and chemical detection rate of steel pipe and welding seam
● 100% detection rate of steel pipe packaging

LSAW Pipes Certificates

We have established a complete quality, safety, environment and management certification system, and won many international product certifications such as American petroleum institute API, EU CE-CPR, EU CE-PED and Russian EAC. From R&D, design, production and processing to testing and delivery of products, we implement a traceability management system and adopts 100% quality control for all key processes, so that everything can be traced. 
API 5L LSAW PIPE
API 5L cetificate
API Specification 5L Certification is a highly authoritative and recognized certification in the global oil and gas industry, specifically designed for pipeline pipes used for transporting oil and gas media. It proves that our lsaw steel pipe manufacturing plant not only has the ability to produce steel pipes that meet the requirements of API 5l specifications, but also its entire quality management system has passed the strict audit of API and continues to accept API supervision. For oil and gas projects (especially cross-border projects), purchasing steel pipes with API 5l certification is usually a mandatory prerequisite. It is the "passport" for products to enter the international market.
