6 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. They are visually examined for conformity to company specifications and tested under the applicable ASTM, ASME, MSS and JIS codes and standards. They are also tested to make sure they conform to their intended use. Upon request, we call in officially certified test agents to witness the inspection procedures. butt-welding fittings are manufactured in conformity with the following standards. APPLICABLE STANDARDS ASTM A Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperatures Service ASTM A0 Wrought Austenitic Stainless Steel Piping Fittings ASTM A Piping Fittings of Wrought Carbon Steel and Alloy Steel for Low-Temperature Service ASME B.9 F actory-made Wrought Steel Butt-Welding Fittings ASME B. Wrought Steel Buttwelding Short Radius Elbows and Returns MSS SP- Wrought Stainless Steel Butt-Welding Fittings MSS SP-7 High Test Wrought Butt Welding Fittings JIS B9 Butt-Welding Pipe Fittings for Light Gauge Stainless Steel Tubes for Ordinary Use JIS B Steel Butt-Welding Pipe Fittings for Ordinary Use JIS B Steel Butt-Welding Pipe Fittings JIS B Steel Plate Butt-Welding Pipe Fittings JIS B Steel Socket-Welding Pipe Fittings JIS B Aluminum and Aluminum Alloy Butt-Welding Pipe Fittings STARTING MATERIAL RECEIVING INSPECTION butt-welding fittings are made of materials which meet ASTM and intracompany specifications. Starting material inspection is carried out as follows: ) Dimensional Inspection Dimensions are inspected at each end of the purchased material. ) Visual Inspection Inspection is performed according to BENKAN's "acceptable surface condition" standard. ) Collating Judgement is made as to whether it 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 Radiographic 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 BENKAN's various working standards. Meeting quality specifications is a key feature of 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 butt-welding fittings is performed as follows: ) Standard Product Inspection Applicable for butt-welding fittings produced under ASME B.9, B. 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. BENKAN's "acceptable surface condition" standard is used as the standard for visual tests.

7 DIMENSIONAL INSPECTION butt-welding fittings are inspected for conformity with ASME or MSS dimensional tolerances (see table on page -7). ) 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 BENKAN. 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. ) Inspection Certificates BENKAN certificates are issued in the following form unless otherwise requested by the customer. INSPECTION BY VARIOUS AUTHORITIES ) Inspection by a Bureau of Shipping Products subject to this inspection are made from starting materials stipulated by the regulations of the bureau. The starting materials and products are inspected for appearance, dimensions, and conformity to designated specifications. The Bureau of Shipping witnesses and certifies inspection, and certificates from them are forwarded to the customer. butt-welding fittings are inspected by the following Bureaus of Shipping: ABS (ABS PACIFIC DIVISION) B.V (Bureau Veritas) LRS (Lloyd's Register ASIA) NK (Nippon Kaiji Kyokai) DNV (Det Norske Veritas) ) Inspection by Other Organizations JIC (Japan Inspection Co.,Ltd.) SGS (SGS FAR EAST LTD.) MOODY INTERNATIONAL LTD.
