It can also supply cement, monitor & control well s sinking, and inject balance liquids etc by the two side outlets on the casing head housing. The casing head manufactured by our company is a standard structure, the casing hanger produced fits well with the casing housing, and the casing hanger of different sizes are available according to the casing procedure and the change of well head conditions. The standard casing head s top connection is API 6B or API 6BX flange.The options of the casing head as followsThe bottom connection of the casing head is either API round box thread and API buttress box thread; it can also be slip type connection. It can be provided with weld supporting base plate. Side outlets could be pipe line thread or studded, studded side outlet is machined with female thread for connecting R1.1/2 reversing valve. Tubing Spool 1.spool and adapter can be designed according to customer's all kinds of models and sizes to meet the requirements in work site. there are three kinds of connecting models for bop 2 connection and outlets. including flanged,studded and clamped-in style.gasket groove is line welded by stainless steel according to API Spec 6A . so as to prolong the using period and decrease the maintaining cost. Structure of Tubing Head Tubing head is usually a spool with both flanged ends, which is set on the top flange of casing head to hang tubing hanger and seal the annular space between the tubing string and oil-layer casing and which consists of tubing head spool and tubing hanger.Functions: 1) Hang the tubing string inside well; 2) Seal the annular space between tubing and casing; 3) Give a crossover to connect casing head downwards and to connect Christmas tree upwards; 4)Provide both side outlets in tubing head spool body through which to execute injection and wellwash operation. Tubing hanger Tubing hanger is an assembly to support tubing string and seal the annular space between tubing and casing, which is connected with tubing and seated into tubing hanger spool by tubing gravity. It is convenient to operate and replace wellhead so that it is widely used for intermediate depth well and common well.Design features1 Fabricated with BT secondary seal, and could be field mounted by cutting casing pipe to accommodate the seal height.2 Tubing hanger and top flange are designed to run cable through.3 Several control ports are available for connecting pipeline. tubing head spool in full accordance with API 6A, the body is made of forged or special smelt steel, providing high bearing strength, safety and reliability. Side outlets could be pipe line thread or studded, studded side outlet is machined with 1.1/2 female thread.Working Pressure2,000psi ~ 15,000psiNominal Bore Size: 2.1/16" ~ 4.1/16"Working MediumCrude oil (gas), mud, drilling fluid, gas (H2S)Temperature LevelL, P, UMaterial GradeEE, FF, HHManufacturing LevelPSL2, PSL3, PSL3G, PSL4StandardsAPI SPEC 6A , API SPEC 16C, NACE MR-0175Hebei Xinhuafa Petroleum Machinery Co., Ltd. is a high-tech enterprise and manufacturer that integrates product design, production and sales and service for oil drilling equipment..
