Quality Control Throughout Production

TORICH applies quality control from incoming material verification to final inspection, packing and shipment. Material identity, production batches and inspection results are recorded to support product consistency and traceability.

During production, dimensions, surface condition and key process results are checked according to the applicable standard, drawing and customer requirements. Final testing is selected according to the material, product type and intended application.

Material identity verified before production
Inspection points arranged throughout processing
Testing selected according to standards and orders
Batch records maintained for product traceability
Quality Workflow

Inspection From Material Entry to Shipment

Quality control is integrated into the production route rather than relying only on a final inspection.

STEP 01

Incoming Material

Material grade, batch identity, dimensions and documentation are reviewed.

STEP 02

Process Control

Key results are checked during forming, heat treatment and finishing.

STEP 03

Final Inspection

Dimensions, straightness, surface condition and marking are verified.

STEP 04

Testing

Chemical, mechanical or non-destructive tests are arranged where required.

STEP 05

Release & Shipment

Inspection records, product identification and packing are checked before dispatch.

Inspection Capabilities

Core Quality-Control Areas

Inspection methods are selected according to the applicable product standard, drawing and confirmed customer specification.

01 / MATERIAL CONTROL

Incoming Material Verification

Material certificates, heat or batch identification, grade, size and visible condition are reviewed before production.

02 / PROCESS CONTROL

In-Process Inspection

Dimensions, surface condition and process results are checked at selected stages during cold forming, heat treatment and finishing.

03 / DIMENSIONAL CONTROL

Dimensional Inspection

OD, ID, wall thickness, length, straightness, ovality and other specified dimensions are measured as applicable.

04 / SURFACE CONTROL

Visual & Surface Examination

Inner and outer surfaces are inspected for visible defects, contamination and conditions that may affect downstream use.

05 / LABORATORY TESTING

Chemical & Mechanical Testing

Testing may include chemical composition, tensile strength, yield strength, elongation, hardness, impact and metallographic examination.

06 / NDT

Non-Destructive Testing

Eddy current, ultrasonic and other non-destructive tests are performed when required by the standard or customer specification.

Testing Overview

Typical Tests and Their Purpose

The final test plan depends on the steel grade, tube type, delivery condition and contractual requirements.

Inspection Category Typical Items Main Purpose
Dimensional Inspection OD, ID, wall thickness, length, straightness and ovality Confirms compliance with the drawing, standard and ordered tolerance.
Surface Examination Inner and outer visual inspection, surface condition and cleanliness Identifies visible defects or conditions that may affect use or processing.
Chemical Analysis Material composition and grade verification Confirms that the material chemistry meets the applicable requirement.
Mechanical Testing Tensile, yield, elongation, hardness and impact where applicable Verifies mechanical properties and the specified delivery condition.
Metallographic Examination Microstructure, grain condition or decarburization where required Evaluates structural characteristics related to processing and performance.
Non-Destructive Testing Eddy current, ultrasonic or other agreed methods Detects relevant surface or internal discontinuities without damaging the tube.
Laboratory & Testing

Inspection Equipment and Test Areas

Replace the images below with photographs of your actual laboratory, dimensional inspection and non-destructive testing equipment.

Chemical composition analysis

Chemical Composition Analysis

Material chemistry is verified according to the applicable grade and order requirements.

Mechanical testing

Mechanical Property Testing

Tensile, yield, elongation, hardness and other properties are tested where required.

Dimensional inspection

Dimensional Inspection

Precision measuring equipment is used to verify critical dimensions and geometric requirements.

Non-destructive testing

Non-Destructive Testing

Eddy current, ultrasonic or other agreed methods are applied according to the inspection plan.

Traceability & Documentation

Records That Support Every Batch

Product identification and inspection records connect the delivered tubes with their material, production batch and applicable test results.

Documentation is prepared according to the product standard and confirmed customer requirements.

  • Heat or Batch Identification
  • Material Test Certificate
  • Chemical Test Results
  • Mechanical Test Results
  • Dimensional Inspection Records
  • NDT Reports When Required
  • Product Marking & Labels
  • Customer-Specified Documents
TORICH combines incoming material control, in-process inspection, laboratory testing, final verification and traceable documentation to support consistent steel tube quality from production to shipment.
