5:Inspection Procedures 

Butt-welding fittings are subjected to strict in-process inspection at each stage of the production process –from starting materials handling to finished product shipping. We are visually examined for conformity to company specifications and tested under the applicable ASTM, ASME, MSS and JIS codes and standards. We are also tested to make sure we conform to our intended use. Upon request, we call in officially certified test agents to witness the inspection procedures. Butt-welding fitting are manufactured in conformity with the following standard.

Applicable standards

ASTM A234 Pipe Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperatures Service

ASTM A403 Wrought Austenitic Stainless Steel Piping Fittings

ASTM A420 Piping Fittings of Wrought Carbon Steel and Alloy Steel for Low- Temperatures Service

.
STARTING MATERIAL RECEIVING INSPECTION

Butt-welding fittings are made of materials which meet ASTM and intracompany specifications.

Starting material inspection is carried out at follows:

1) Dimensional Inspection

Dimensions are inspected at each end of the purchased material.

2) Visual Inspection

Inspected is performed according to OK Fitting . “acceptable surface condition” standard.

3) Collating

Judgement is made as to whether is worthy of the inspection by computorised collating the described items with the materials certificates.

The following other inspections are performed if necessary.

- Ultrasonic Examination  - Magnetic Particle Examination  - Liquid Penetrant Examination

- Ultrasonic Thickness Inspection  - Mechanical Test

- Others


IN-PROCESS INSPECTION


Butt-welding fittings are manufactured with carefully selected materials of the finest metallurgical quality on well-controlled jigs, tools or molds based on ok fitting  Various working standards. Meeting quality specifications is a key feature of ok fitting  butt-welding fittings.

The following are the major in-process inspection items.

- Visual Inspection  - Dimensional Inspection  - Shape Inspection  - Hardness Test

- Temperature Check  - Processing Conditions Check  - Material Identification ( by marking )

- Others

FINAL INSPECTION

The final inspection of ok fitting butt-welding fitting is performed as follows:

1) Standard Product Inspection

Applicable for ok fitting butt-welding fittings produced under ASME B16.9 and other specifications

VISUAL INSPECTION

Butt-welding fittings are visually inspected to confirm that both internal and external surfaces are smooth and without harmful defects. ok fitting . “acceptable surface condition” standard is used as the standard for visual tests.

DIMENSIONAL INSPECTION

Butt-welding fittings are inspected for conformity with ASME or MSS and JIS dimensional tolerances


2) Special Product Inspection

Applicable for every products manufactured to meet specifications requested by customers.


VISUAL INSPECTION

Butt-welding fittings are visually inspected. Criteria are based on those of the standard product.

Special specifications are determined by agreement between the customer and ok fitting 

DIMENSIONAL INSPECTION

The inspection is usually based on specifications stipulated by the customer.

SPECIAL INSPECTION

In the case of special requirements specified by the customer, nondestructive examinations and mechanical tests are performed.
