Fokas long ol rot bilong testim, makim ol rot bilong mekim insulation leia tiknes, ol tes bilong win-taitnes, na ol thermal konduktiviti mesamen, i nidim wanpela random sekim bilong klostu-sel reit Gutpela moa o wankain olsem 88%, na insulesen leit tiknes tolerans ±3 mm{4}}
2. Straksel Disain na ol samting bilong wokim ol samting
Komposit Straksa Leya Rikwaemen
Wok stiel paip: DN800 paip i mas yusim Q235B spiral weldim paip (SY/T5037-2000) o 20# ol stiel stiel paip (GB/T8163-2018), wantaim anti-korosen tritmen i kamap long Sa2.5 gret na kotim wantaim 3PE leia;
Insulesen leja: Polyurethane densiti Bikpela moa long o wankain olsem 55 kg/m3 (nesenel standet daunbilo limit), wantaim silikon karbaid filing o airgel intaleia ol i nidim long ol hai-temperesa senario, tiknes 50–100 mm (ol i stretim bihainim ol operesen kondisen);
Kasing bilong HDPE ausait i mas winim 15 kV spak tes, na faiberglas ausait kesing i mekim klorait ion permeabiliti i kamap gutpela long 30%.
Spesel Scenario Adaptesen Stendet
Oil/Gas Fil: Ol paip bilong ain i wok i mas bihainim GB/T 9711-2017 (standet bilong spiral sim i stap aninit long ol stiel paip);
High-Temperature Pipes (>140 digri ): Yusim ol steel-klad stiel ausait straksa, wantaim galvanais steel tep tiknes Gutpela moa o wankain olsem 0{{3}5 mm.
