Sinochem Group Chemical Construction Standard · Central SOE Standards
Sinochem Holdings' Chemical Engineering Construction Standards (hereinafter referred to as "Sinochem Construction Standards") is a corporate-level engineering technology and management specification system developed by Sinochem Holdings Co., Ltd. through its domestic and international chemical engineering project practices, covering the entire lifecycle of design, procurement, construction, commissioning, and operations & maintenance. It is not a single document, but rather a "standards family" comprising a series of corporate standards, management manuals, technical guidelines, and operating procedures, serving the construction activities of Sinochem Holdings and its subsidiary engineering companies and general contractors on refining & petrochemical, fertilizer, fluorochemical, fine chemical, and new energy materials projects both domestically and overseas.
The background behind its formulation can be understood from three perspectives. First, business drivers: Sinochem Holdings' business spans petrochemicals, agrochemicals, fluorochemicals, new materials, and other sectors, with highly diversified project types. In the early years, subsidiaries "operated independently," and inconsistent standards led to confusion in design interfaces, misaligned procurement specifications, and uneven construction quality. Second, internationalization needs: as projects along the "Belt and Road" increased, Sinochem needed to develop an intermediate-layer standard that is "adaptable and implementable" — one that satisfies Chinese national standards while remaining compatible with internationally accepted standards (such as ASME, API, IEC, EN) and the local codes of host countries. Third, safety and compliance pressure: chemical projects demand extremely high intrinsic safety requirements, compounded by overseas environmental, labor, and HSE compliance requirements, which compelled the company to establish internal control standards that exceed the minimum compliance line.
In terms of scope of application, Sinochem Construction Standards primarily apply to new construction, expansion, and modification chemical and energy engineering projects controlled or led by Sinochem Holdings, both domestically and overseas — particularly those adopting the EPC/EPCm general contracting model with participation from Sinochem-affiliated engineering companies (in coordination with relevant units of China Chemical Engineering). For equity-participation projects or pure technical consulting projects, they typically serve as reference documents rather than mandatory constraints. It should be noted that for specific standard numbers, version numbers, and mandatory clause lists, please refer to the officially published standard documents of Sinochem Holdings and the technical annexes of project contracts. This article focuses on a systematic interpretation and does not replace the original texts.

The core logic of Sinochem Construction Standards can be summarized as "one main thread, four pillars": with full-lifecycle quality and safety control as the main thread, and design, procurement, construction, and commissioning & O&M as the four pillars. The following expands on five key points.
Sinochem projects often face the coexistence of three systems: "Chinese national standards + international standards + local standards." The core handling principle of its design standards is:
| Scenario | Handling Principle |
|---|---|
| Chinese national standard is stricter than local standard | Apply Chinese national standard |
| Local standard is stricter than Chinese national standard | Apply local standard |
| Owner specifies international standard | Apply the standard stipulated in the contract |
| None of the three systems covers the issue | Determined by special review of the project technical committee |
This "apply the higher standard" principle is the key that distinguishes Sinochem Construction Standards from simply adopting national standards. The design phase also emphasizes an interface management matrix, which clearly defines the condition delivery milestones among process, piping, electrical, instrumentation, and civil disciplines, reducing the "design rework" commonly seen in overseas projects.
The core of the procurement phase is the Approved Vendor List (AVL) and material equivalence substitution rules. Overseas projects often require substitute materials due to local procurement difficulties or long logistics cycles. Sinochem Standards establish a clear equivalence determination process for this:
This process prevents safety hazards caused by "arbitrary substitution" and addresses overseas owners' concerns about material traceability.
The most prominent feature of the construction standards is HSE (Health, Safety, and Environment) front-loading — safety is not an appendage to construction but a precondition for commencing work. Typical requirements include:
Sinochem Standards emphasize that "construction serves commissioning." The commissioning phase is divided into three stages: single-unit commissioning, integrated commissioning, and feed-in commissioning, each with a clear acceptance checklist. At the O&M handover stage, four sets of documents are required: As-Built models, equipment registers, spare parts lists, and operating procedures, ensuring the owner can "take over smoothly and operate steadily."
In recent years, Sinochem Construction Standards have progressively incorporated digital delivery requirements, including 3D model delivery, intelligent P&IDs, and Electronic Document Management Systems (EDMS). Overseas projects particularly emphasize bilingual documentation and local regulatory compliance statements to facilitate host country approvals.

| Comparison Dimension | Sinochem Construction Standards | Chinese National Standards (GB/SH/HG) | International Standards (ASME/API/IEC/EN) | Local Standards (e.g., Middle East, Southeast Asia) |
|---|---|---|---|---|
| Nature | Corporate internal control standards family | National/industry mandatory or recommended | Internationally accepted technical codes | Host country regulations/codes |
| Coverage | Full lifecycle + management | Technology-focused, design & construction-oriented | Equipment, materials, process-oriented | Approval, environmental, labor-oriented |
| Strictness | Generally "apply the higher standard" | Moderately strict | High (especially pressure equipment) | Varies widely |
| Overseas applicability | Requires grafting with local standards | Requires transformation | High acceptance | Mandatory application |
| Flexibility | Relatively high (project-customizable) | Relatively low | Moderate | Low |
In short, Sinochem Construction Standards represent an integration layer that is "national standards as the foundation, international standards as reference, and local standards as constraints." Their value lies in reducing conflicts and duplication among the three sets of standards.

Scenario 1: Sinochem Quanzhou Petrochemical Refining & Chemical Integration Project. This is a publicly reported large-scale refining and chemical project involving multiple units such as atmospheric and vacuum distillation, catalytic cracking, and ethylene. In such projects, Sinochem Construction Standards are used to unify design interfaces and construction quality control across all units. Particularly during multi-unit parallel construction, standardized hold points and document systems significantly reduce coordination costs.
Scenario 2: Sinochem's fertilizer/chemical projects in "Belt and Road" countries. Public reports indicate that Sinochem has participated in fertilizer and chemical engineering construction in Southeast Asia, the Middle East, Africa, and other regions. These projects often face incomplete local standards and owners specifying European or American standards. The "apply the higher standard" principle and equivalence substitution process of Sinochem Construction Standards become key tools for balancing cost and compliance.
Scenario 3: Sinochem's new energy materials projects (e.g., lithium battery materials, fluorochemical new materials). Such projects involve new processes and rapid iteration. Public reports show Sinochem's continued investment in fluorochemicals and new energy materials. The role of Sinochem Construction Standards in these projects is more about rapid replication of construction experience and standardization of commissioning and O&M.

Q1: Are Sinochem Construction Standards mandatory?
For projects controlled or led by Sinochem Holdings, they are typically mandatory constraints stipulated in contracts; for equity-participation or cooperative projects, they are mostly for reference. The specific terms are subject to the technical annexes of the contract.
Q2: For overseas projects, should Chinese or international standards be used?
It depends on contract stipulations and host country regulations. The principle of Sinochem Standards is "apply the higher standard," but ultimately the owner's and local approval requirements prevail.
Q3: Who has the final say on material equivalence substitution?
Joint sign-off by design, procurement, and quality departments is required. For special equipment, confirmation from a third-party inspection agency is also needed. The construction contractor cannot make unilateral decisions.
Q4: What is the relationship between Sinochem Standards and China Chemical Engineering's standards?
Both belong to the chemical engineering construction field, with overlap and synergy. However, Sinochem Construction Standards focus more on the internal control requirements of Sinochem Holdings as the owner/general contractor. For specific relationships, please refer to official documents from both parties.
Q5: Is digital delivery a mandatory requirement?
In recent years, most new projects have incorporated it as a requirement, but older or smaller projects may be exempted. The project contract shall prevail.

1. Conduct a "standards gap matrix" before project kickoff: Compare Chinese national standards, international standards, and local standards clause by clause, identifying conflict items and "higher standard" items to avoid discovering problems during the construction phase.
2. Establish a project-level AVL and equivalence substitution register: Overseas procurement cycles are long. Locking in approved vendors and substitute material lists in advance can save substantial schedule time.
3. Front-load HSE and hold points: Incorporate JSA, HAZOP briefings, and hold point plans as pre-commencement conditions. Do not wait until the construction crew arrives to catch up.
4. Start bilingual documentation from day one: Document rework costs for overseas projects are extremely high. It is recommended to generate bilingual versions simultaneously during the design phase.
5. Synchronize commissioning and O&M documents with construction: Do not wait until completion to compile As-Built documents and equipment registers — archive them as construction progresses.
6. Standardize localized workforce training: Make safety training into replicable modules to reduce dependence on Chinese personnel.
7. Leverage third-party inspection: Introduce agencies such as TÜV, BV, and SGS for special equipment and critical materials to satisfy owners and reduce risk.
8. Maintain traceability in standard version management: Sinochem Standards are updated periodically. Projects should lock in the applicable version to avoid disputes arising from "mid-project standard changes."
