Pipeline System has an attractive option for consideration, we are proud to offer mechanically lined pipe manufactured to API 5LD that offers corrosion resistance at a fraction of the price of previous materials.


Our patented manufacturing process produces superior finished products. Our process eliminates distortion of the CRA liner. There is significantly less variation of the inner layer when compared to traditionally manufactured lined pipes that are hydrostatically formed. Our process yields significant benefits to the customer: principally allowing uniform circumferential welds, limiting dilution with superior weld strength. En outre, our manufacturing process produces exceptional grip strength between base metal and CRA liner.

Today's competitive environment compels businesses to seek every possible advantage. Les entreprises intelligentes examinent toutes les possibilités, y compris les avantages matériels. Les nouvelles technologies des matériaux et les nouveaux procédés de fabrication résolvent des problèmes qui avaient auparavant des cycles de vie des produits limités et créé une exposition à des défaillances coûteuses sur le terrain. Secteurs dont Pétrole & gaz, Chimique, Power and Construction for example, are encountering applications where corrosion, high temperatures and pressures, and wear are limiting the lifespan or capabilities of their products and projects.

Previously, solid alloy or weld clad products have been the best options available, but those are both costly and can have extremely long lead times.




Nos tuyaux et tubes sont constitués d'un matériau de support en acier au carbone fabriqué selon l'API, Spécifications ASTM et ASME actuellement reconnues et acceptées par l'industrie dans le monde entier, marié à des alliages résistants à la corrosion (CRA's) sélectionné par le client pour le besoin de projet individuel. The number of CRA options available is large, y compris 300 series stainless steels and many other UNS alloys with the ability to deter corrosion and cracking. Our patented manufacturing process offers both technical and economic advantage.

We also offer several end finishes, manufactured to facilitate on-site welding, among which the overlay welding is the most prevailing solution. Incorrect or non-uniform end finishes take additional time to install in the field and can mitigate the benefit of the CRA liner. We work with each customer to ensure they are provided with the best end finish solution to assist in rapid and cost effective installation. en outre, we manufacture each piece to the customer's specified length, reducing required installation resources by providing a factory finished end exactly where it is needed.

Solution : Overlay welding

Boring on the ID of pipe ends, then overlay weld on the backing steel ID, last lathe on the overlay weld layer and bevel the pipe ends.

Processus de fabrication : 

Traditionally lined pipe has been manufactured a couple of ways. One method places a CRA liner on a base metal plate and explosively welds the two, and then the plate is traditionally rolled and welded, resulting in an ERW pipe with a bimetal construction, Or the CRA liner was fabricated, slid into the pipe and then hydrostatically stretched to fit the outed base metal. We have developed and patented a different and superior solution. We insert a CRA liner and compress the two materials together. Our process results in the higher grip strengths and unparalleled liner uniformity.
