KMK 2.04.10-97 PDF

Full title and description

KMK 2.04.10-97 — "Instructions for design of process steel pipelines with Pn up to 10 MPa" (Russian: Инструкция по проектированию технологических стальных трубопроводов Ру до 10 МПа). The document provides normative guidance for design, materials, joining, supports and testing of technological (process) steel piping used in industrial plants where nominal pressure does not exceed 10 MPa.

Abstract

This instruction specifies practical rules and requirements for the engineering design of steel process pipelines used to transport liquids and gases in industrial technological systems at nominal pressures up to 10 MPa. Topics include design limits (pressure and temperature ranges), material and wall-thickness selection, strength calculation principles, supports and expansion arrangements, welding and jointing requirements, pressure testing and inspection, and measures for corrosion protection and insulation. The document served as a national KMK-series design guidance and has later been superseded by an updated SHNK edition.

Scope

Applies to the design of technological steel pipelines (process piping) with nominal pressure up to 10 MPa used inside industrial sites and installations. Typical applicability covers a broad range of process fluids (liquids and gases), pipe diameters commonly treated by the instruction (historically up to around 1,400 mm in related national rules), and extended temperature ranges encountered in plant piping. The instruction is targeted at design-phase requirements (strength, allowable stresses, wall thickness, routing and supports), fabrication/joining quality (welding and inspection) and pre-commissioning pressure testing.

Key topics and requirements

• Design pressure and temperature limits (nominal pressure up to 10 MPa; guidance for low and high temperature ranges).
• Material selection and allowable stresses for steel pipes and fittings.
• Strength and thickness calculation methods for pipe walls and fittings.
• Routing, supports, anchors, and expansion/compensation arrangements (expansion loops, anchors, guides).
• Welding, jointing, nondestructive testing and acceptance criteria for welded connections.
• Hydrostatic and pneumatic testing procedures and inspection before commissioning.
• Corrosion protection, coatings, insulation and protection of buried or exposed pipelines.
• Requirements for documentation, drawings, and as-built records for safe operation and maintenance.

Typical use and users

Used by mechanical/process engineers, piping designers, project engineers, EPC contractors, plant owners/operators and inspection bodies responsible for design, fabrication and commissioning of industrial process piping systems (chemical, petrochemical, oil & gas processing units, utility piping in industrial plants). It serves as a design and verification reference for engineering offices and construction organizations operating under the national KMK framework.

Related standards

Commonly referenced or related documents include earlier Soviet-era instructions (e.g., СН 527-80 / SN 527-80 covering design of steel process pipelines), regional and international piping standards such as EN 13480 (metallic industrial piping), ISO 3183 (steel pipe for pipelines) and the later national replacement SHNK 2.04.10-22 (which updates the KMK 2.04.10-97 content).

FAQ

Q: What is this standard?

A: KMK 2.04.10-97 is a national instruction (KMK-series) that provides design guidance for technological steel pipelines with nominal pressure up to 10 MPa. It was issued in the KMK collection as the 1997 edition.

Q: What does it cover?

A: It covers design principles for process piping: allowable stresses and wall-thickness decisions, material selection, welding and jointing requirements, supports and expansion arrangements, testing and inspection procedures, and protective measures such as coatings and insulation. The scope is typical for industrial process piping within the stated pressure and temperature ranges.

Q: Who typically uses it?

A: Mechanical and piping engineers, EPC contractors, plant designers, inspection and commissioning personnel, and facility owners/operators who need national-design-rule guidance for process piping in industrial plants under the KMK framework.

Q: Is it current or superseded?

A: KMK 2.04.10-97 has been listed as replaced by SHNK 2.04.10-22. Users planning new designs should consult the SHNK 2.04.10-22 edition (the active replacement) and confirm applicability with the current national regulatory body.

Q: Is it part of a series?

A: Yes — it is part of the KMK series (national construction/design norms and instructions). KMK includes multiple related KMK/SHNK items addressing piping, equipment, insulation, boilers, and other building/industrial design topics; some KMK items have been updated or reissued under SHNK identifiers.

Q: What are the key keywords?

A: Process piping, steel pipelines, design instruction, nominal pressure 10 MPa, piping supports, welding, hydrostatic testing, corrosion protection, KMK, SHNK.
