Spacer Spools are essential components commonly used in the oilfield for wellhead extensions, choke and kill manifolds, and other critical systems. Designed and manufactured according to the API 6A standard, these spools typically feature identical nominal end connections, ensuring compatibility and reliability in high-pressure environments.
Jianhu Jielin Petrochemical Machinery Co., Ltd. is located in the Jianhu Industrial Park in Jiangsu Province, a region known as "the land flowing with milk and honey." As a modern, large-scale enterprise, we specialize in the research, development, manufacturing, and sale of various oilfield equipment and spare parts. Our products are certified by the China Classification Society and hold API-6A, API-16A, and API-16C certifications.
We primarily produce high- and medium-pressure API 6A valves, with working pressures ranging from PN2.5 to 105MPa and nominal diameters from DN3 to DN1000mm. In addition, we manufacture a wide range of API 6A wellhead equipment, including choke and kill manifolds, mud manifolds, drilling accessories, and blowout preventers.
Our company follows the philosophy of "management improvement, quality focus, market expansion, and brand building." With high-quality products, competitive pricing, and excellent customer service, we sincerely seek long-term cooperation with clients both domestically and internationally.
Below is a detailed specification table:
| Working Pressure | 2000PSI - 20000PSI |

These spacer spools are designed for durability and performance in demanding oil and gas environments. Whether for onshore or offshore applications, our products meet the highest industry standards and are trusted by professionals around the world.
Wear Resistant Steel Plate
1.Wear-resisting Steel Plate is composed of low Carbon Steel Plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
2.Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.
3.The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
4.The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.
