2.5 Base materials / Ancillary materials Base materialsThe base material for manufacturing hot-rolled coils as a preliminary material for steel pipe for oil and gas pipelines is iron (percentage by mass >= 99.5%). Other primary components include carbon, silicon and manganese. Chemical composition varies depending on the type of steel. The detailed percentages by mass are indicated in Part 3183 of the /DIN EN ISO 3183/.Polyethylene or polypropylene is used as an anti-corrosion coating.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 in Siegen and Hamm. Pipe manufactureThe process is divided into three phases: forming connected strips to an open V-shaped pipe, welding and annealing 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 required length. Processing (coating)The pipes are blasted and heated to the required application temperature prior to coating. Polyethylene and polypropylene are applied by means of sleeve extrusion. The coated pipe string is then quenched in a cooling line. Both Mannesmann Line Pipe GmbH sites are certified according 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/InstallationWeldingThe steels can be welded manually or automatically after each of these procedures. At outdoor temperatures of less than +5 °C, preheating of a sufficiently wide zone to 80 to 200 °C is recommended.

In any case, the surface should be moisture-free. Stress-relief heat treatment (see heat treatment) is not generally necessary and should only be carried out if demanded by a construction regulation or when welded constructions and/or operating conditions recommend a reduction of internal welding stresses. Appropriate welding consumables shall be used for arc welding; basic electrodes shall be used for grades with specified minimum yield strength of 360 N / mm² or more. If necessary, corrosion protection should be supplemented in the pipe connecting area. Industrial health and safety protection measures:No health protection measures over and beyond the standard industrial safety measures (e.g. protective gloves) are required during processing/installation of the pipes. Environmental protection measures:No 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:Residual packaging material at the construction site must be collected separately. The specifications of local waste authorities must be maintained during processing.

2.9 PackagingSteel pipe for oil and gas pipelines is bundled using steel bands and/or shipped on wooden beams, secured with wooden wedges (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 use:The material composition during the use phase corresponds to that at the time of production. Steel pipe for oil and gas pipelines is manufactured from unalloyed and low-alloyed structural steel and fine-grained steel. Please refer to section 2.6.

2.11 Environment and health during useGeneral health and environmental aspects:There are no health risks for users of steel pipe for oil and gas pipelines or for persons manufacturing or processing steel pipe for oil and gas pipelines. From an environmental perspective, there are no restrictions governing the use of steel pipe for oil and gas pipelines.

2.12 Reference service lifeThe life cycle of steel pipe for oil and gas pipelines is dependent on the respective structural design, use and maintenance. The use phase for steel pipe for oil and gas pipelines is not depicted as they involve maintenance-free and generally durable products.

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 also considered. As pipelines for oil and gas involve composite pipes, the individual materials are separated in Module C3 and then directed to their designated purposes in Modules C4 and/or D, respectively. The material and energy expenses required for Module C3 and the ensuing emissions are ignored. In accordance with the selected scenario, thermal utilisation of the plastic coating takes place in Module C4, whereas emissions generated are allocated to this module, and the generated thermal and electric energy is credited to Module D.

3.3 Estimates and assumptionsThe basic material for manufacturing “pipelines for oil and gas” is low-alloyed hot-rolled strips produced 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 criteriaThe end-of-life stage involves 1% product losses. Possible landfilling is ignored. Likewise, the manufacture and utilisation of packaging material (steel bands, wooden beams) are not considered. The use of lubricants and national transports of raw materials excluding the hot-rolled coil used are also ignored.Nevertheless, in total these unconsidered 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 is 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 pipelines for oil and gas 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.

5 Environmental Product Declaration Mannesmann Line Pipe GmbH – Oil and Gas Pipelines

Allocations in the use of recycled materialsThe use of steel scrap for the production of hot-rolled strips is regarded as unencumbered for Modules A1-A3. However, a large percentage of scrap requirements is already covered by 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 recycled (see section based on /ECSC/). Recycling credits are allocated in line with the “theoretically 100% primary blast furnace route” approach /Worldsteel 2011/. Credits from thermal utilisation of calorific waste materialsCalorific waste during the end-of-life stage (polyolefins as PE and PP) is directed to thermal utilisation,

whereby the waste incineration processes applied are based on partial-flow analyses of the respective materials (PE and PP) with an energy efficiency factor of less than 0.6. Accordingly, all ensuing emissions and waste are allocated to Module C4 while the credits for thermal and electric energy generated are considered in Module D. Credits are allocated via the power mix used and the steam generation based on natural gas.

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 consideration of the results of the environmental impacts according to various Life Cycle Inventory Analysis categories for “pipelines for oil and gas” indicates the dominance of upstream steel production (“steel” category) in practically all environmental impacts. With the exception of the ADPe (Abiotic Depletion Potential for non-fossil resources) impact category, the relative percentage accounted for by the “steel” category is generally well over 60%. The ADPe environmental category is characterised by the “auxiliaries” Life Cycle Inventory Analysis category and in particular by the use of epoxy resin here. Accounting for approx. 20%, electricity generation represents the next largest share here while steel production and preparation/provision of the cooling and

process water each account for a share of just over 5%. All in all, “auxiliaries” can be classified as the second most important category, especially since it accounts for 35% of the ODP (Ozone Depletion Potential) where consumption of the requisite polyolefin (PE/PP) is decisive. Electricity generation (“electricity” category) is attributed a subordinate significance, generally accounting for shares of less than 5%. 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 “natural gas” category.

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. Consideration of the individual product stages of the declared modules in relation to the production stage (= 100%) indicates that waste processing (C4) only accounts for a relevant share of around 5% in the environmental category of Global Warming Potential

(GWP); this accounts for less than 1% in the other categories. The “Module D” column represents the cumulative total of loads and credits for the selected scenarios in this product stage. In combination with high collection rates, this generally results in high credits for steel products during the end-of-life phase. Only the ODP (Ozone Depletion Potential) and ADPe (Abiotic Depletion Potential for non-fossil resources) categories are attributed additional loads through recycling which are caused by increased electricity consumption by the EAF. Environmental impacts, incl. Module D
