2 Isulatig joit IK Mooblock isulatig joits are boltless, rigid pipelie compoets, factory-welded ad ready for istallatio a desig which has prove sucessful throughout the world eve for highest requiremets maiteace-free suitable for udergroud istallatio without the eed for special precautios or for above groud istallatio absolutely o impairmet due to exteral iflueces Mechaical properties the excellet mechaical properties are achieved by a rigid desig of statically favourable form, usig thermo-settig plastics free from cold flow as isulatig materials the welded uit provides a safe ad reliable coectio eve over extremely log period of operatio without the risk of the secured ad locked uit looseig or separatig coutless tests, prototype tests ad empirical data gaied durig the course of may years of practical operatio cofirm the soudess ad correctess of the complete welded desig Electrical properties the dimesioig ad practical arragemet of the isulatig sectios withi the overall desig i additio to techical productio factors, i cojuctio with isulatio materials of a suitable quality, result i the ideal overall electrical behaviour of the isulatig joits large exteral isulatig legth, thus elimiatig the possibility of sparkover very good dielectric stregth, substatially greater tha is the case with covetioal isulatig flages the average electrical resistace, measured at 1000 VDC, exceeds 40 Mohm a decisive factor i safe operatig behaviour, however, is lierarity betwee the voltage applied ad the resistive leakage curret Calculatio i accordace with Germa stadards such as DIN 240, TRBF, ASME code ad other iteratioal stadards, or i accordace with specific requiremets if o other regulatios are made, the RMA-compay stadards (DIN-stadards) are valid. Thus for the calculatio ad for the stregth characteristics of the desig the workig pressure, resp. the maximum test pressure is decisive additioal forces such as bedig momets ad tesile forces etc. must be specified by the customer basically, all compoets of forces ad force values occurig ca be take ito cosideratio durig desig calculatio a uiform assessmet, valid simultaeously for all applicatios ad requiremets is ot possible i practice Scope of maufacture urestricted, i.e. extedig beyod the data ad tables g i v e the umerical values specified i the brochure are based upo assumed stadard versios deviatios ad matchig to specific operatig coditios may be implemeted at ay time Materials pipes, e.g. i accordace with DIN, API, ASTM-A ad other stadards seamless rigs made of plate material or of forged quality, depedig upo requiremets ad desig calculatios seals of agig-resistat material, e.g. bua N, vito, EPDM ad other materials. isulatig materials made of tried ad tested materials with applicatio-specific properties Exteral coatig uless otherwise specified, we apply PUR (Polyurethae) acc. to DIN 3061 as a stadard other types of coatig are possible accordig to agreemet ad purpose Examples: bitume primer, coal tar epoxy resi ad others Iteral liig as per stadard without liig virtually all types of liig ca be applied upo agreemet, depedig upo iteded purpose electrically coductive media ad deposits require a appropriate iteral liig Tests/Ispectios accordig to the agreed requiremets, usually: - a stregth ad tightess test with water - a electrical breakdow test with 0 V/1 miute, AC, 50 Hz (both before ad after the hydrostatic pressure test) - a electrical resistace test, stadard V. I special cases 1000 V DC - checkig the material certificates - evaluatio of the destructive ad o destructive tests - dimesioal checks depedig upo the basis of the order, the tests are coducted either by our quality assurace departmet, by a official acceptace testig agecy, by the customer himself or by a acceptace testig compay authorized by the customer Qualificatios for isulatig joits compoet testig i accordace with Germa regulatios (VDTÜV 1066) stress tests ad bedig tests multifuctioal prototype tests i all rages up to 60 ad other quality assurace tests Techical modificatios reserved Scope of applicatio suitable for flow media such as mieral oil, crude oil, kerosie, gasolie, propae, butae, atural gas, coal gas, ethylee, itroge ad drikig water etc. Media such as sour gas ad oxyge ecessitate special materials ad desig bases please always specify the medium ad operatig coditios stadard versios up to maximum + C costat temperature special versios for district heatig pipelies up to +150 C 2
