Technical details and manufacturing context for Chock Body

Definition
The Chock Body is a cast steel component used in basic metal manufacturing, primarily serving as a structural support and alignment element for piping systems. It is designed to accommodate pipes with nominal diameters ranging from 50 to 600 mm (per GB/T 1047) and to withstand nominal pressures from 1.6 to 4.0 MPa (per GB/T 1048). The component is manufactured from cast steel grade ZG270-500 (per GB/T 11352), which provides a balance of strength and weldability. Mechanical properties include a tensile strength of 500–650 MPa, yield strength of 270–350 MPa, elongation of 18–22%, and impact toughness of 27–40 J at -20°C (per GB/T 228.1 and GB/T 229). Hardness ranges from 140 to 200 HBW (per GB/T 231.1). The operating temperature range is -29°C to 300°C, limited by the seal material. Surface roughness on sealing faces is 3.2–6.3 μm (per GB/T 1031), and dimensional tolerance is ±0.5 mm (per GB/T 1804). Weight varies from 10 to 500 kg depending on size and pressure class. These parameters are reference ranges; actual values must be confirmed for the specific model and application. The Chock Body is a component, not a standalone product, and its suitability depends on the piping system design, flange ratings, and service conditions. Verification of material grade, dimensions, and compliance with applicable standards should be performed with the legal manufacturer or supplier before procurement.
Working Principle
The Chock Body functions as a rigid support that transfers mechanical loads from piping to a foundation or structure, maintaining alignment and preventing excessive stress on flanges and joints. It accommodates thermal expansion and contraction within the operating temperature range, while its cast steel construction provides structural integrity under pressure. The component interfaces with flanges and pipe sections, and its sealing surface finish ensures proper gasket seating. Selection requires consideration of nominal diameter, pressure class, temperature, and material compatibility. Maintenance signals include visible deformation, cracking, or corrosion, which may indicate overloading or material degradation. Failure boundaries are defined by yield strength and impact toughness; exceeding these limits can lead to permanent deformation or fracture.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive erosion
Cause: High-velocity flow of drilling fluids containing solid particles (cuttings, proppant) wearing away the internal surfaces, especially in high-pressure zones.
Cavitation
Cause: Rapid pressure drops across the chock body during flow control, causing vapor bubble formation and implosion that pits and erodes the material, often due to improper valve throttling or design mismatch.
Maintenance Indicators
  • Visible external leakage of hydraulic fluid or wellbore fluids around seals or body connections
  • Unusual high-frequency vibration or hammering noise during operation indicating flow instability or internal damage
Engineering Tips
  • Implement regular ultrasonic thickness testing on critical internal surfaces to monitor erosion rates and schedule replacements before failure
  • Optimize flow control procedures to avoid prolonged throttling at low openings, and use hardened or coated materials (e.g., tungsten carbide) in erosion-prone areas

Frequently Asked Questions

What is the material grade of the Chock Body?

The material grade is ZG270-500 per GB/T 11352, which is a cast steel grade. This grade provides a tensile strength of 500-650 MPa and yield strength of 270-350 MPa, as listed in the directory. Always confirm the actual material grade with the supplier for your specific order.

What are the available size and pressure ranges?

The nominal diameter ranges from 50 to 600 mm (per GB/T 1047), and the nominal pressure ranges from 1.6 to 4.0 MPa (per GB/T 1048). These are reference ranges; the exact size and pressure rating must be selected based on your piping system requirements and verified with the manufacturer.

What is the operating temperature limit?

The operating temperature range is -29°C to 300°C, as limited by the seal material. This range is a reference; actual limits depend on the specific seal and application. Verify with the supplier for your intended service conditions.
