Tianjin Dalipu Oil Country Tubular Goods Co., Ltd supplies this 139.7mm outer diameter L80-13Cr plain end pipe, designed for use in oil and gas well environments where carbon dioxide corrosion is a primary concern. The L80 grade is an API 5CT specified material with a minimum yield strength of 552 MPa (80,000 psi) and a minimum tensile strength of 655 MPa (95,000 psi). The 13% chromium content provides significantly better resistance to CO2-induced corrosion than standard carbon steel grades like J55 or K55.
L80-13Cr is a martensitic stainless steel grade widely specified in the international OCTG market for sour service and mildly corrosive well conditions. Typical chemical composition includes 12-14% chromium, 0.15-0.22% carbon, and controlled levels of manganese, silicon, and molybdenum. The plain end (PE) design means the pipe ends are cut square and not threaded, giving the buyer flexibility to apply proprietary connection types or threading specifications at a later stage. Wall thickness for 139.7mm OCTG pipe commonly ranges from 6.98mm to 10.54mm depending on the weight class selected.
This pipe is sourced by upstream oil and gas operators, drilling contractors, and OCTG trading companies for casing and tubing programs in wells with moderate to high CO2 content. Tianjin Dalipu is based in Jinghai, Tianjin, a region with a concentration of steel pipe manufacturing. Buyers should confirm the exact weight per foot, wall thickness, and connection type required, as these vary by well design. Pricing, lead time, and minimum order quantity are not listed and must be negotiated directly with the supplier.

The profile does not include details on the company's manufacturing capabilities, API or ISO certifications, number of employees, or export history. The response rate is 0.00%, meaning there is no verified data on how quickly the supplier responds to enquiries. Buyers should request API monogram licensing details, mill test certificates for previous orders, and evidence of third-party inspection capabilities before proceeding with a purchase.
The 139.7 mm L80-13Cr PE pipe is a high-chromium OCTG plain end tubular designed for sour service and corrosive oil and gas environments. L80-13Cr offers superior corrosion resistance in CO2-rich well conditions, making it ideal for casing, tubing, and line pipe applications in upstream petroleum operations. This material grade is widely specified in international oilfield projects and traded globally as a certified OCTG commodity.

Before placing an order for L80-13Cr pipe from Tianjin Dalipu, verify that the supplier holds a valid API 5CT license for the L80 grade and that the mill can produce 13% chromium steel to the required chemical composition. Request mill test certificates from recent production runs and cross-check the mechanical properties against API 5CT Table C.6 or E.6 requirements. For critical well applications, consider engaging a third-party inspection agency to witness production and testing.
Confirm the exact shipping terms, port of export, and packaging method. OCTG pipe is typically shipped in bundles or loose, with thread protectors fitted to threaded ends. Since this is plain end pipe, confirm how the ends are protected during transit. Ask the supplier for a detailed packing list, estimated gross weight, and cubic measurement to plan your logistics. Tianjin port is the most likely export point for a Jinghai-based supplier, but confirm this directly.
Quality assurance for OCTG involves verifying chemical composition, tensile properties, hardness, impact toughness, and non-destructive test results. For L80-13Cr specifically, check that the heat treatment (quench and temper) is documented and that the hardness does not exceed 23 HRC as per API 5CT limits. Request the material test report (MTR) in EN 10204 3.1 format at minimum, and for high-specification projects, consider requiring 3.2 certification witnessed by an independent body.
