1. Gnéithe teicniúla 1.1 Sonraíocht ábhair: 304 (cosúil le 0Cr18Ni9) 1.2 Meán oibre: uisce, uisce bog 1.3 Brú deartha: 1.4 Brú oibre: 5Kg/CM2 1.5 Brú tástála: 7.5Kg/CM2
2. The preparation of this project is based on 2.1 F43C technical documents. 2.2 National Standard GB50236-98 "Code for Construction and Acceptance of Welding Engineering for Field Equipment and Industrial Pipelines" 2.3 National Standard GB50235-97 "Code for Construction and Acceptance of Industrial Metal Pipelines" 2.4 Welding Procedure Evaluation Report of the Company :HG1
3. Welders 3.1 Welders should have the qualification certificate of welder examination stipulated in "Rules for Welder Examination of Boiler and Pressure Vessel Pressure Pipeline Welders". 3.2 After entering the site, the welder shall first pass the actual welding operation examination according to the provisions of GB50236-98, and can only undertake the welding work of this project after being approved and issued by the general contractor.
4. Cigireacht táthú 4.1 Ba cheart go mbeadh cigirí táthú eolach ar dhoiciméid theicniúla F43C agus ar chaighdeáin náisiúnta ábhartha agus ar an bpróiseas seo. 4.2 Cigireacht, líonadh agus glacadh le hábhair inchaite táthú píopa de réir na rialachán. 4.3 Maoirseacht agus iniúchadh cuimsitheach a dhéanamh ar cibé an gcuireann an welder an próiseas seo i bhfeidhm, agus oideachas a chur ar na sáraitheoirí agus cabhrú leo.
1. Help to be corrected. For serious violators or those who do not change their education, they have the right to stop the welding work. to ensure welding quality. 4.4 Do a good job in Article 7 "post-welding inspection and management" of this process. 4.5 Invite and welcome inspectors from the general contractor and the supervisor to inspect the welding quality.
5. Preparations before welding 5.1.1 Pipes and welding materials must have qualified certificates that meet the regulations, and be checked with the physical objects. 5.1.2 The type of pipe material is grade 304, which is equivalent to my country's 0Cr18Ni9 specification standard. As specified in the project drawings. 5.1.3 Model and specification of stainless steel welding wire: H{{20}}Cr20Ni10Ti φ2.5mm φ2.0mm 5.1.4 Model and specification of stainless steel electrode: A132 φ3.2mm φ2.5mm 5.1.5 Model and specification of cerium tungsten electrode: WCe-20 φ2.0mm 5.1.6 The argon gas was 99.99 percent pure. 5.2 Preparation of Weldments 5.2.1 The distribution of welding ports must comply with the national standards GB50235-97 and GB50236-98
Rialacháin lucht leanúna. 5.2.2 Is groove múnlaithe V- é an píopa, agus comhfhreagraíonn na hailt agus na grúpaí butt do na ceanglais i bhFíor 1: Nóta: Is é an bearna de 3.54mm na sonraí le linn táthú. Nuair a ghrúpáil-chun-táthú soladach a phointeáil, ba cheart go mbeadh sé níos mó ná na sonraí seo mar chúiteamh ar an gcrapadh.
