Mcneil Alloys is a dependable manufacturer, supplier, exporter, distributor, and wholesaler of carbon steel pipe fittings manufactured in accordance with ASTM A105 and ASTM A234 grades including WPB, WP11, WP22, and WP91. These grades are widely specified for pressure piping systems where strength, durability, and temperature resistance are critical. ASTM A105 fittings are commonly used for forged components in ambient and moderate temperature service, while ASTM A234 grades are designed for seamless and welded butt welding pipe fittings used in high-pressure and elevated-temperature pipelines.
The combined range of ASTM A234 WPB, WP11, WP22, and WP91 pipe fittings provides flexibility across carbon steel and low-alloy steel applications, covering requirements from standard pressure service to high-temperature and creep-resistant environments. WPB is suitable for general carbon steel piping, whereas WP11, WP22, and WP91 contain alloying elements such as chromium and molybdenum to enhance strength, oxidation resistance, and long-term stability under thermal stress. As an experienced steel pipe distributor and pipe fitting distributor, Mcneil Alloys supplies these grades with consistent quality, precise dimensions, and reliable availability across Dubai, Abu Dhabi, Sharjah, Fujairah, and Ras Al Khaimah, along with export supply to Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain.
