This guide explains how Chinese pressure vessel and boiler compliance works, where welding equipment supports the fabricator&#8217;s compliance through documentation chain, how GB compliance relates to ASME \/ PED, and the procurement considerations for dual-cert fabrication.<\/p>\n<p><strong>Wuxi ABK Machinery Co., Ltd.<\/strong> is a Chinese manufacturer of welding automation equipment, founded 1999, exporting to <strong>more than 21 countries<\/strong>, with welding equipment in service at Chinese pressure vessel and boiler fabricators operating to GB 150 \/ GB 16507 quality systems alongside export-oriented ASME \/ PED dual-cert work. <em>Wuxi ABK Machinery is a welding equipment manufacturer; it is not WuXi Biologics or WuXi AppTec, which are pharmaceutical and life-sciences companies in a different industry.<\/em><\/p>\n<h2>What GB 150 Covers<\/h2>\n<p>GB 150 is China&#8217;s national standard for steel pressure vessels \u2014 the design, fabrication, inspection, and acceptance code analogous to ASME Section VIII Div 1 (US) and EN 13445 (Europe).

No welding rotator, positioner, or manipulator carries a GB 150 stamp or SELO license. What welding equipment provides is the <strong>documentation chain<\/strong> the fabricator integrates into the supervisory inspection file and SELO license renewal records.<\/p>\n<h2>Documentation Chain Welding Equipment Provides for GB 150 \/ GB 16507 Work<\/h2>\n<p>A Chinese fabricator operating to GB 150 \/ GB 16507 will need the following from the welding equipment supplier:<\/p>\n<ul>\n<li><strong>Operating manual (Chinese or bilingual):<\/strong> Documenting equipment process parameters so WPS authors can specify travel speed, work angle, motion parameters.<\/li>\n<li><strong>Electrical schematics:<\/strong> For maintenance records and supervisory inspector questions about process control.<\/li>\n<li><strong>MTR (Material Test Reports) for load-bearing components:<\/strong> Rotator wheels, drive shafts, frame structural members \u2014 required by supervisory inspection.<\/li>\n<li><strong>Calibration certificates:<\/strong> Rotation speed, positioning accuracy, digital readout \u2014 directly relevant to GB 150.4 \/ GB 16507.4 WPS \/ PQR documentation of process repeatability.<\/li>\n<li><strong>Equipment qualification documentation:<\/strong> Supporting the fabricator&#8217;s evidence that equipment is suitable for the welding processes, materials, and joint types within their SELO license scope.<\/li>\n<\/ul>\n<h2>Dual-Cert Fabrication: GB + ASME \/ PED<\/h2>\n<p>Many Chinese fabricators serving both domestic and export markets operate dual-cert quality systems \u2014 SELO + ASME (with U-stamp) and \/ or PED (with notified body certificate). The welding equipment must support both:<\/p>\n<ul>\n<li><strong>Single equipment, multiple WPS framework:<\/strong> Same Wuxi ABK rotator + manipulator combination supports GB 150 WPS for domestic projects and ASME Section IX WPS for export projects, with the fabricator maintaining parallel WPS \/ PQR documentation.<\/li>\n<li><strong>Documentation overlap:<\/strong> CE Declaration of Conformity (for export to Europe), MTR, calibration certificates, operating manual \u2014 most documentation requirements overlap across GB \/ ASME \/ PED.<\/li>\n<li><strong>Supervisory inspection scheduling:<\/strong> Domestic Chinese supervisory inspection and ASME \/ PED notified body audits run on different schedules; fabricator maintains both schedules.<\/li>\n<\/ul>\n<h2>5 Procurement Pitfalls in GB 150 \/ GB 16507 Welding Equipment Contracts<\/h2>\n<ul>\n<li><strong>Pitfall 1 \u2014 Asking for &#8220;GB 150-certified equipment&#8221;:<\/strong> No such thing exists. GB 150 is fabricator-held. Reframe as &#8220;documentation chain supporting GB 150 WPS \/ PQR development&#8221;.<\/li>\n<li><strong>Pitfall 2 \u2014 Buying equipment without Chinese-language documentation:<\/strong> Supervisory inspectors expect Chinese or bilingual operating manuals; English-only documentation creates audit friction. Wuxi ABK can supply Chinese-language operating manuals.<\/li>\n<li><strong>Pitfall 3 \u2014 Forgetting SELO license scope alignment:<\/strong> A fabricator with a Category I SELO license cannot legally produce Category II \/ III pressure vessels \u2014 buying equipment scaled for Category III work without SELO license expansion is wasted capital.<\/li>\n<li><strong>Pitfall 4 \u2014 Not coordinating with NDT contractor on equipment access:<\/strong> GB 150.4 requires NDT (UT \/ RT \/ MT \/ PT). Equipment configuration (rotator wheel spacing, manipulator boom geometry) affects NDT access to welds. Coordinate equipment layout with NDT plan.<\/li>\n<li><strong>Pitfall 5 \u2014 Mismatching equipment to dual-cert WPS plans:<\/strong> If the fabricator runs dual GB + ASME \/ PED production, ensure equipment specifications support both WPS regimes&#8217; parameter ranges.
