Full title and description

RD 26-02-80-2004 — "Змеевики сварные для трубчатых печей. Требования к проектированию, изготовлению и поставке" (English: "Welded coils for tubular furnaces. Requirements for design, manufacture and supply"). This industry guidance covers technical requirements for radiant and convective welded coils and their elements used in tubular process furnaces in oil‑refining, petrochemical, chemical and gas industries.

Abstract

This RD establishes design, material, manufacturing, welding, inspection and delivery requirements for welded heat‑exchange coils (radiant and convective coils) used in tubular furnaces. It specifies allowable operating conditions (wall temperature and working pressure), acceptance and testing procedures (including mandatory non‑destructive testing), marking, packaging, transport, storage and manufacturer guarantees. The document is intended to ensure safe, reliable and repeatable manufacture and supply of furnace coils for heavy process industries.

Scope

The RD applies to welded radiant and convective coils and their components for tubular furnaces used in oil‑refining, petrochemical, chemical and gas industries. It covers equipment designed for coil wall temperatures up to 760 °C and working pressures up to 16 MPa (160 kgf/cm²). The document sets requirements for design, materials, fabrication, welding, heat treatment, non‑destructive inspection, acceptance testing, documentation, marking, packaging, transport, storage and operation; it excludes coils for pressure vessels and radiant coils for reaction furnaces.

Key topics and requirements

• Types, main parameters and dimensional limits for coils (tube diameters, lengths, heat‑exchange surface, etc.).
• Design requirements to ensure manufacturability, assembly and serviceability (including recommendations for transportable prefabricated blocks).
• Material selection and material condition specifications for tubes, sheet parts and castings (with references to relevant GOST/TU standards).
• Welding requirements and welding consumables; general welding rules, preheat/post‑weld heat treatment where applicable.
• Mandatory quality control of welds: 100% ultrasonic or radiographic inspection of welded joints (method selected to best detect unacceptable defects), plus procedures for repeated testing and acceptance criteria.
• Fabrication controls, thermal treatment regimes, and time limits between welding and heat treatment for specific steel grades.
• Acceptance tests and manufacturer acceptance procedures: dimensional checks, NDT, hydraulic (or acoustic‑monitored pneumatic) tests, surface quality, completeness, marking and packaging.
• Documentation, marking, conservations/temporary corrosion protection, packaging, transport and storage requirements; required contents of the product passport and delivery documentation.
• Operational requirements, commissioning (including winter start/stop and leak testing regulations in an annex), and manufacturer guarantees (minimum warranty provisions).

Typical use and users

Primary users are design and mechanical engineers, fabrication shops and welders producing furnace coils, NDT and quality control specialists, procurement and inspection teams at refineries and petrochemical plants, and regulatory/oversight personnel responsible for pressure‑equipment and furnace safety. The RD is used when specifying coil design and procurement, developing fabrication and inspection plans, and preparing technical documentation (passports, test reports, packing lists).

Related standards

The RD references a number of national and industry standards and rules that are normative for materials, welding, NDT and safety. Examples include: GOST 12.3.009‑76 (safety for lifting/transport operations), GOST 9.014‑78 (temporary corrosion protection), GOST 550‑75 (seamless steel tubes for petrochemical industry), PB 09‑563‑03 and PB 09‑540‑03 (industrial safety rules for oil‑refining and petrochemical plants), RDI/sectoral instructions on ultrasonic and radiographic control, and RD 3688‑. . (requirements for tubular heating furnaces). These normative references are listed in the RD's bibliography.

FAQ

Q: What is this standard?

A: RD 26‑02‑80‑2004 is an industry guidance document that sets technical requirements for welded coils used in tubular process furnaces (design, manufacture, testing and supply). It was developed and published by OAO VNIINEFTEMASH and is intended for the oil‑refining, petrochemical, chemical and gas industries.

Q: What does it cover?

A: It covers coil types and parameters, materials, tubes and sheet parts, castings, welding materials and procedures, manufacturing practices, heat treatment, weld quality requirements including 100% ultrasonic or radiographic inspection, acceptance tests (including hydraulic/pneumatic options), documentation, marking, packaging, transport, storage and operational guidance (including an annex for winter commissioning).

Q: Who typically uses it?

A: Design and process engineers, fabrication and welding shops, quality assurance and NDT inspectors, procurement/specification authors at refineries and petrochemical plants, and inspection/regulatory bodies responsible for process‑furnace equipment.

Q: Is it current or superseded?

A: Public records list RD 26‑02‑80‑2004 as active (действует). The document was introduced on 06 May 2004 and the revised/printed edition was issued in 2007; amendments (including one dated 20 Dec 2013) have been recorded. It replaces RD 26‑02‑80‑88.
