Quality
To ensure the safe installation of your piping system, we provide a strict quality assurance for the pipes we manufacture.Having undergone extensive testing,our pipes are guaranteed to operate reliably for many years.We never ship defective or non-conforming products,as this would have a significant impact on our reputation.
why choose us
Comprehensive quality inspection
Chemical composition analysis is performed to confirm the grade.
Physical and mechanical property testing includes tensile strength,hardness,bending,and flattening tests.
Surface appearance inspection includes checks for scratches,black spots,and flatness.
Non-destructive testing includes RT (radiographic testing),UT (ultrasonic testing),ET (eddy current testing),and PT (penetrant testing).
Corrosion resistance tests,such as intergranular corrosion testing.
Hydrostatic testing is conducted to check for leaks or deformation under high pressure.

Test Equipments & What We Test
Manual polishing of the pipes
Workers use hand tools or handheld machines to grind and polish the surfaces of metal pipes.It is typically used for small-batch production,custom designs,or complex geometries that automated systems cannot handle.
Manual polishing of the inside of pipes
Polishing the inner walls of pipes is a highly specialized process, typically performed to meet hygiene standards in the food, pharmaceutical, and medical industries and prevent bacterial growth.
Air Blowing
Air blowing of steel pipes is a critical step in the pre-commissioning and maintenance of industrial piping systems,designed to remove weld slag, rust, dust, and construction debris from the interior of the pipes.
High Pressure Water Jetting
High-pressure water jetting is a technique that involves pressurizing ordinary water and propelling it through a specialized nozzle as a high-speed jet to clean the inner and outer walls of pipes,remove blockages,or perform surface treatment.
YSSM R&D Test Lab
Our laboratory utilizes state-of-the-art equipment to detect hidden defects in pipe products and conducts tests such as chemical composition analysis,physical and mechanical property testing,surface appearance inspection,non-destructive testing,corrosion resistance testing and hydrostatic testing.
A recording operation is in progress
Our staff accurately records the data after each test.This is done with precision down to each individual steel pipe to facilitate subsequent inspections.

what we do for
Quality Assurance
Chemical composition analysis
Chemical composition analysis is a scientific process used to identify and quantify the chemical elements and compounds within a material.
In industries like piping and manufacturing,it acts as a critical quality assurance tool to verify that raw materials meet specific grade standards.
Physical & mechanical property testing
Physical & Mechanical Property Testing is a critical evaluation process used to determine how a material performs under real-world conditions.
While chemical analysis identifies what a material is made of,these tests measure its physical behavior and structural integrity.
Surface appearance inspection
Surface appearance inspection is a critical quality assurance process used to evaluate the exterior condition and visual integrity of a product.
It identifies surface-level defects that could compromise performance or longevity,such as cracks, scratches, pitting, corrosion,or uneven coatings.
Non-destructive testing
Non-destructive testing (NDT) is a sophisticated quality assurance technique used to evaluate the integrity and properties of a material without causing any permanent damage.
Unlike mechanical testing,NDT allows components to remain fully functional after inspection,making it ideal for high-stakes industries like piping and aerospace.
Corrosion resistance tests
Corrosion resistance tests are essential quality assurance procedures designed to evaluate how a material withstands chemical or environmental deterioration over time.
In industries like piping and marine engineering,these tests simulate harsh conditions—such as exposure to salt spray,acids,or high humidity—to predict a product’s service life and durability.
Hydrostatic
testing
Hydrostatic testing is a critical quality assurance method used to evaluate the structural integrity and leak-tightness of pressurized systems,such as pipes,tanks,and boilers.
The process involves filling the component with a liquid—usually water—and increasing the pressure to a level higher than its maximum operating limit for a specific duration.
