2. Product

2.1 Product description / Product definitionSteel Oil Country Tubular Goods (OCTG) involve pipes made of unalloyed and low-alloyed structural steel and fine-grade steel. This Environmental Product Declaration refers to products recorded in the /API 5CT/ (Casings and Tubings), for example.

2.2 ApplicationOCTG are used for oil and gas wells conveying hydrocarbons but are also used in other areas of applications such as geothermics, CCS, oil and gas caverns, for example.

2.3 Technical DataThe mechanical and technological properties of Oil Country Tubular Goods are listed in Table C.5 of /API 5 CT/ and/or API SPEC 5CT + ERTA 1 + ERTA 2:2016-10, for example.

Technical construction data (API 5 CT as an example)

Name Value UnitYield strength Pipe /ASTM A370/ 276 - 759 N/mm2

Tensile strength Pipe /ASTM A370/ 414 - 862 N/mm2

Notched-bar impact value /ASTM A370/ 27 Joule

Hardness /ASTM E110/ (for areas > 50 mm) max. 30 HRC

2.4 Delivery statusOCTG steel grades are in accordance with /API 5 CT/ and/or API SPEC 5CT + ERTA 1 + ERTA 2:2016-10 are specified in groups 1 to 4.

2.5 Base materials / Ancillary materials Base materialsThe base material for manufacturing hot-rolled coils as a preliminary material for Oil Country Tubular Goods is iron (percentage by mass >= 99.5%). Other primary components are carbon, silicon and manganese. Chemical composition varies depending on the steel


grade. The detailed percentages by mass are indicated in the /API 5 CT/, for example. Ancillary materials:Various lubricants depending on the respective rolling process

2.6 ManufactureHot-rolled strips of appropriate width and thickness, wound as coils, serve as the preliminary material for manufacturing longitudinal welded steel pipes at the pipe manufacturer, Mannesmann Line Pipe.

There are two production facilities with identical manufacturing methods located in Siegen and Hamm. Pipe manufactureThe process is divided into three phases: forming connected strips to an open V-shaped pipe, welding and normalised annealing of the seam in order to achieve the appropriate micro structure. The heated strip edges are welded together by pressing. The pipes are rounded and straightened followed by non-destructive testing of the HFI seam. The pipe string is then cut to the requisite length. Processing (hot-finished OCTG)Using inductors, the cold-finished pipes referred to above are heated to more than 870 °C. Pipes are normalised or quench-and-tempered (QT) for manufacturing hot-finished OCTG. Production speed ranges from 0.5 to 4.0 m/min. Both sites are certified to /DIN EN ISO 9001/ and /API Q1/ for product manufacturing and quality assurance.

2.7 Environment and health during manufacturing

During the entire manufacturing process, no other health protection measures are required extending beyond the legally specified industrial protection measures for commercial enterprises. Certification of industrial safety and health protection in accordance with OHSAS 18001 is in place for both sites. Via regular analyses of the environmental impacts and permanent improvement measures and action within the framework of TQM (Total Quality Management), the environmental impacts attributable to the manufacturing process are continuously minimised. Both Mannesmann Line Pipe GmbH production facilities are certified according to /DIN EN ISO 14001/ and /DIN EN 50001/ in terms of environmental and energy Management.

2.8 Product processing/InstallationPipe connectionJ55 and N80Q pipe grades are weldable and can be ordered accordingly. But oil field pipes are usually connected using so-called API circular threads, BTC or premium threads. Usually OCTG are threaded and coupled (API round or BTC threads) or connected by Premium Threads. Threading is sub-contracted. Industrial health and safety protection measuresNo health protection measures over and beyond the standard industrial safety measures (e.g. protective gloves) are required during processing/installation of the OCTG.

Environmental protection measuresNo noteworthy environmental pollution is triggered by processing/assembling the products in question. No special measures need to be taken to protect the environment. Residual material incurredResidual material and packaging incurred on the building site must be collected separately. The specifications of local waste authorities must be maintained during processing.

2.9 PackagingOCTG with O.D. of up to 168.3 mm (6 5/8”) can be bundled using steel bands and/or shipped on wooden beams, secured with wooden wedges, which may even be suitable for larger dimensions (waste code numbers: 150103 packaging made of wood, 150104 packaging made of metal). All packaging can be re-used.

2.10 Condition of useContents in condition of useThe material composition during the utilisation phase corresponds to that at the time of production. OCTG are manufactured from unalloyed or low-alloyed structural steel and fine-grained steel. Please refer to section 2.6.

2.11 Environment and health during useGeneral health and environmental aspectsThere are no health risks for users of OCTG or for persons manufacturing or processing OCTG. From an environmental perspective, there are no restrictions governing the use of OCTG.

2.12 Reference service lifeOCTG life cycles are dependent on the respective structure design, use and maintenance. The use phase for OCTG is not depicted as they involve maintenance-free and generally durable products.

2.13 Extraordinary effects

FireOCTG comply with the requirements of construction product class A1 “non-flammable” in accordance with /DIN 4102, Part 1/ and /DIN EN 13501-1/. No smoke gas develops. Fire protectionName ValueBuilding material class A1

WaterThe effects of flooding on OCTG neither lead to any changes in product reliability nor to any other negative environmental Impact.

Mechanical destructionIn the event of extraordinary mechanical impact, steel components display very good characteristics thanks to the high degree of ductility (plastic deformation) of the material. In general, no chips, breaking edges or similar exist.

2.14 Re-use phaseSteel pipe for oil and gas pipelines is 100% recyclable.


Steel pipe for oil and gas pipelines can be directed to electro-steel plants as scrap at the EoL.

2.15 DisposalAs steel is 100% recyclable, this material does not require disposal. Waste code in accordance with the European List of Wastes (EWC), as per the European List of Wastes Ordinance /AVV/: 17 04 05 Iron and steel.

3. LCA: Calculation rules

3.1 Declared UnitAs a representative of the group of cold- and hot-finished Oil Country Tubular Goods (OCTG), 1 metric tonne of hot-finished Oil Country Tubular Goods serves as the declared unit.

Conversion factor to 1 kg 0.001 -

3.2 System boundaryType of EPD: cradle to plant gate – with options

The EPD comprises the following life cycle phases: Product stage (Modules A1-A3) End-of-life stage (Modules C3-C4) Benefits and loads beyond the system

boundary (Module D)

Modules A1-A3 comprise both the upstream chain of production and provision of raw materials, ancillary materials and energy resources as well as transport thereof to the plant and the energy expenses incurred there. Furthermore, waste water treatment is considered.It is assumed for Module C3 that there are no further material or energetic expenses for waste processing and that the decommissioned pipes are directed to the scenario in Module D. Accordingly, there is also no scenario necessary for Module C4, waste processing.

3.3 Estimates and assumptionsThe basic material for manufacturing the Oil Country Tubular Goods (OCTG) is low-alloyed hot-rolled steel strips via the blast furnace route with production facilities in Germany. The production of hot-rolled strips is represented by a generic and EN15804-conformant GaBi data set /GaBi ts/.

3.4 Cut-off criteriaend-of-life scenario involves product losses of 1%. Possible landfilling is ignored. Likewise, the manufacture and utilisation of packaging material (steel bands, wooden beams) are not considered. Nor is the use of lubricants taken into consideration. Nevertheless, in total these neglected flows significantly comply with the cut-off criterion of max. 5% of energy and mass expenditure while also adhering to the criterion of 1% in relation to individual processes, /PCR, Part A/.

3.5 Background dataThe LCA results of the declared product are based on modelling in the GaBi ts software environment. Modelling depends on primary production data and the energy and media consumption values for an entire year.This was supplemented by basic materials in the GaBi data base. The respective documentation can be reviewed online, /GaBi ts/.

3.6 Data qualityThe primary background data used refers to fiscal 2012. The annual volumes have been examined for representativity in relation to previous years.The GaBi data base (DB version 6.115, SP 29) /GaBi ts/ with the corresponding basic material data sets was last updated in 2016.

3.7 Period under reviewThe period under review is fiscal 2012. The volumes of hot-finished Oil Country Tubular Goods (OCTG) produced in 2012 serve as averages for the Declaration.

3.8 AllocationAllocations in productionBy using the “Steel hot-rolled coil /EN15804 A1-A3/” /GaBi ts/ data set, indirect allocations are applied by mass, market value, calorific value and exergy in Module A1. Allocations in the use of recycled materialsThe use of steel scrap for the production of hot-rolled coil is regarded as unencumbered for Modules A1-A3. However, a large percentage of scrap requirements is already covered by the cutting losses incurred during pipe production.In a consideration of the end-of-life scenario, the remaining requirements are initially covered by scrap volumes incurred after the use phase. The net scrap volume is calculated from the difference between the two. Credits from recyclingThe net scrap volume is then recycled (see section based on /ECSC/). Recycling credits are allocated in line with the “theoretically 100% primary blast furnace route” approach, /Worldsteel 2011/.

3.9 ComparabilityBasically, a comparison or an evaluation of EPD data is only possible if all the data sets to be compared were created according to /EN 15804/ and the building context, respectively the product-specific characteristics of performance, are taken into account. The used background database has to be mentioned.

6. LCA: Interpretation

A detailed analysis of the environmental impacts in terms of the LCA of the product under review by classifying the Life Cycle Inventory Analysis flows indicates the strong influence of hot-rolled steel strip production (A1) on the production stage as a whole (A1-A3, see graphic). Apart from ADPe (Abiotic Depletion Potential for non-fossil resources), the remaining environmental impacts are dominated by more than 85% by steel production. With the exception of electricity consumption, the remaining categories play an insignificant role. With a share of more than 75% of electricity required for production (in relation to the declared product), these environmental impacts can be largely allocated to processing (heat treatment + reforming).

Around 80% of the ADPe impact category is determined by electricity consumption and in equal parts by upstream steel production and the provision/treatment of cooling and process water. Transport, both to the plant site (“transport” category) and within the plant (“diesel” category), has practically no influence on the LCA results. The same also applies for the “auxiliaries” and “natural gas” categories.


Environmental impacts of Modules A1-A3

Steel – as a material with inherent properties – is infinitely recyclable. Therefore, the aim when analysing steel products is to consider end-of-life scenarios in particular and analyse them comprehensively across all life cycle phases. Recycling is carried out in an established electric arc furnace (EAF) process. The substitution of primary steel production gives rise to LCA advantages as the loads incurred by the expenses associated with primary steel production are offset against relatively low loads incurred during

recycling. The Global Warming Potential (GWP) result in Module D, for example, represents the total loads and benefits. In combination with very high collection rates, this generally results in high credits for steel products during the end-of-life phase. Only the ODP (Ozone Depletion Potential) category is attributed additional loads by recycling. These can be attributed to the increased use of electricity by the EAF route compared to the furnace route. Environmental impacts, incl. Module D
