1. mud pump premium chromium  liners

premium chromium liners;
Outer #45 forge steel, inner- 27% Cr.
All items made by API 7K standard

Liners have Four types: premium chromium liners/ceramicliners/chromium-plated liners/ hardened liners

All items are manufactured to API 7K quality standards.

Premium Liners: made witha high chrome/iron sleeve or bi-metal sleeve into a forged steel hull.

Ceramic Liners: combinethe strength of a forged steel outer shell with the abrasion andcorrosion resistance of a ceramic inner sleeve.provide zirconia sleeves as wellas alumina sleeves.

Chromium-Plated Liners: made from premium forged steel with the core plated by chrome.

Hardened Liners: these liners are hardened and heat treated under strict quality control to a minimum of 60RChardness. Each liner is honed to amirror-like finish for smooth.

The HRC can be from 60-64.

All liners are used for mud pump of long life.

2. Features of Mud pump Liners:

Liners are the main damageable parts in mud pumps for development drilling. The ceramic liner (zirconium and other compound materials) has the features of long service life time, wear-resistance and erosion-resistance. Its average life time ismore 5 times longer than the metal cylinder. Honestly, its own weak point is that there could be some fracture when the ceramic cylinder is impacted violently by other object. To guarantee the safe operation of the components and avoid breaking the ceramic liners, the following safety guidelines should be noted before installation:

(1) When installing the cylinder, it is better to use the special tool or follow the instruction below;

(2)Strictly prohibit flinging knocking or impacting the cylinder, if you need to put down, you shouldmove it as slowly and careful as you can;

(3) Strictly prohibit hitting ceramic cylinder with hammer or other heavy objects (including the metal shuck of the cylinder). When hitting, wood or other materials should be used asbuffer cushion;

(4) When you use hammer orother heavy objects to hit or strike the cylinder (especially for pressure cap,piston crown, piston rod), you should control the appreciated angle and force.Otherwise, the impact force which has been transferred to the cylinder willpossible fracture the ceramic liner of cylinder;

(5) Before the installationofpiston, you should check whether there is any damage on the metal shuck ofpiston crown. There should be at least 0.20mm installation clearance between themaximum outer diameter of the piston and inner diameter of ceramic liner,otherwise, ceramic liner could possible be damaged;

(6) After the installation,the side-friction between the metal part of piston and ceramic wall of thecylinder should be avoided. If it does happen, you should rectify as quickly asyou can;
