ASTM A182 F316L Stainless Steel Cap Forged Threaded Pipe Fitting
TONG CHUANG is one of the leading manufacturers， traders， suppliers and exporters of ASTM A403 WP304 Socket Welded Pipe Fittings industry in China. Stainless steel A182 F316L contains higher chromium and lower carbon content. Lower carbon means less chromium carbide precipitation due to welding. The carbon content of this steel is as low as 0.03%， which reduces its susceptibility to intergranular corrosion. This steel can be continuously exposed to temperatures of about 1500°F without significant fouling.
它适用于各种应用，如汽车顶盖、机械部件、螺钉和食品处理设备。我们提供不同形式的 DIN 1.4404 不锈钢对焊管件，如三通、异径管、四通、短弯头、弯头和端盖。SS UNS S30400 对焊管弯头具有出色的成型和焊接性能。这种钢还具有出色的抗氧化性。我们在最先进的基础设施内按照国际标准开发所有产品，以实现最高质量。
The ASTM A182 F316L specification covers forged or rolled alloy and stainless steel pipe flanges， forged fittings， and valves and parts for high temperature service. After the forging is hot worked， it should be cooled to a specific temperature before heat treatment， and it should be carried out according to the requirements of the type of heat treatment， austenitization/solution temperature， cooling medium， quenching， etc. Materials should meet the required chemical composition of carbon， manganese， phosphorus， silicon， nickel， chromium， molybdenum， columbium， titanium. The material shall meet the mechanical property requirements of the grade ordered， such as tensile strength， yield strength， elongation， Brinell hardness. All grades H and F 63 shall be tested for average grain size.
A socket weld is a pipe connection detail in which the pipe is inserted into a recessed area of a valve， fitting or flange. Compared to butt weld fittings， socket weld fittings are primarily used for Small Bore Piping; typically for pipes with a nominal diameter of NPS 2 or less.
To connect pipes to valves and fittings or other parts of the pipe， angle seal welds can be used. Socket welded joint construction is a good choice because high leakage integrity and excellent structural strength are important design considerations.
由于使用角焊缝和突变的配合几何形状，抗疲劳性低于对接焊结构，但仍优于大多数机械连接方法。
SW fittings are a family of high pressure fittings used in a variety of industrial processes.
它们只用于 ASME 管，尺寸范围相同。
They are used in areas where plumbing is permanent and are designed to provide good flow characteristics.
They are produced to multiple ASTM standards and manufactured to ASME B16.11. The B16.11 standard covers pressure-temperature ratings， dimensions， tolerances， markings， and material requirements for wrought carbon and alloy steels. Acceptable material forms are forgings， bar，， and that meet ASTM A105， A182， or A350 for fitting chemistry， melting practices， and mechanical properties.
它们有三个压力等级：3000、6000 和 9000。
对齐不需要临时点焊，因为原则上配件可以确保正确对齐。
Weld metal must not penetrate the pipe hole.
它们可以代替螺纹接头，因此泄漏的风险大大降低。
对角焊缝进行射线照相并不现实，因此，正确的装配和焊接至关重要。角焊缝可通过表面检测、磁粉 (MP) 或液体渗透 (PT) 检测方法进行检测。
Construction costs are lower than butt-welded joints due to the lack of strict assembly requirements and the elimination of special machining for butt-weld end preparation.
ASTM A182 F316L Forged Socket Weld Fittings are a low carbon version of 316 and are not affected by sensitization (grain boundary carbide precipitation). Therefore， it is widely used for heavy-duty welded parts (about 6mm and more). There is usually no discernible price difference between 316 and 316L stainless steel.
ASTM A182 F316L 锻制承插焊管件是标准的钼等级，在奥氏体不锈钢中的重要性仅次于 304。
与 304 相比，钼为 316 带来了更好的整体耐腐蚀性，尤其是在氯化物环境中具有更高的耐点蚀和缝隙腐蚀性能。
奥氏体结构还赋予了这些牌号极佳的韧性，即使在低温条件下也是如此。
与铬镍奥氏体不锈钢相比，316L 不锈钢在高温下具有更高的蠕变、断裂应力和抗拉强度。
TONG CHUANG supplies a full line of ASTM A182 F316L Forged Socket Weld Fittings， including elbows， tees， reducers， end caps， joints， and more.
