Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service
ASTM A234/A234M – 15
Scope
This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. The M in the designation stands for metric.
Materials
The starting material for fittings shall be fully killed steel, consisting of forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added and shall conform to the chemical requirements. Unless otherwise specified for carbon steel plates and sheet, the steel may be made to either coarse grain or fine grain practice. Grade WP9 shall be made to fine grain practice.
Chemical Requirements
NOTE 1: All requirements are maximum unless otherwise indicated.
NOTE 2: Where an ellipsis (...) appears in this table, there is no requirement and analysis for the element need not be determined or reported.
Quality Control
Whilst providing a quality, trusted service, we also place a high premium on quality craftsmanship. Our steel products are long-lasting, and always meet our clients exact specifications.

Testing:
The production and inspection technological process of our company is arranged according to production standards, and we also establishes professional inspection organization which takes charge of the quality inspection of all process from raw material into the company to the final product store up. Inspections including destructive testing and non-destructive testing.
Our range of steel pipe testing equipment is among the most expansive in the seamless tube manufacturing industry. This equipment is essential for testing both the chemical and physical properties of each seamless pipe and the material used to make it. It also allows us to detect hidden steel tube defects, ensuring the pipe quality. Listed below is our primary range of testing equipment currently in operation.
1. Eddy current flaw detector
2. Ultrasonic flaw detector
3. Optical spectrum analyzer
4. Universal testing machine
5. Tensile strength tester, impact tester, hydrostatic test equipment, length measuring and weighing instruments.
